What would you like to see in future phone APIs

Article
04/02/2007

We are in the phone app team. The Phone app is the app that is used to make and manage voice calls.
We are trying to understand how the developers use the phone app or would like to use the phone as a platform. We would like you to answer the following questions.
1. What are the things you wanted to programmatically do on the phone system, that you weren’t able to do?
2. From the things that you were able to do, what were the pain points?
3. What kind of phone (dialer, makecall, incoming calls etc) related apps do you write, such as answering phone call and replying to sender with SMS when in a meeting ?
4. What kinds of phone UI extensibility are you interested in, such as changing the color of the text in the accumulator.
5. What kind of technology (managed/native) do you primarily use for writing your apps?
6. What type of phone related notifications (from the notification broker) does your app listen to, generally, such as signal strength notification?
7. What type of phone related notifications (from the notification broker) do you wish your app could receive?

Can you now also help us prioritize your requests?. If you had $100, how would you distribute it on your requests. (We are looking for inputs similar to here, but only for phone API related stuff)

Thanks,

JJ, Lakshmi.

Any sort of API to get the cell tower ID and other information for ghetto location-based services for the vast majority of people without unlimited data plans. How in the world is someone going to get their location information from a cell tower ID? Community databases. Other than that, the existing phone APIs are great.

Thanks for seeking the feedback. My top priority item would be the ability to plugin my own call control on top of the native dialer UI. I would like my app to get notified on various phone UI activities and want to be able to do control the call. Basically, I am asking for an API set for the UI alone, I can do the the call control part through TAPI. Thank you!

I would like to see an API, to make an datacall (GSMData). Now you have to use the complex TAPI, to get this done.

if you wish to make data calls, you can look into the connection manager APIs. Look up ConnMgrEstablishConnection.

Currently I'm using the RIL layer intensely (and Broker where possible). What's missing is broad device support (Operators tend to leave out many features) and better documentation for the implemented features. Also USSD on CDMA devices is not supported via API's (GSM is supported) Duplex sound control in call (for Answering machine type app.)

The ability to chose to run at 96 or 192dpi on VGA and bigger screens without having to reset the device. Is this possible. May I remind everyone that VGA based PPC or PPC phones have the poorest graphic performances. Yes ! Even the X51v and its graphic chip. When apps take the graphic chip into account, its fine, but otherwise, it is really really slow. Plus this VGA thing is mostly marketing, because it displays buttons and interface the QVGA way. And all VGA PPC don't have graphic chip, so writing an app just for one or 2 devices isn't really what I want. So I want the ability to get back to 96dpi from 192dpi without having to reboot the device. Thanks.

Hi! Better calling history and logging between the Outlook PIM and the Phone. Tighter integration with the Calendar as well. When a call comes in, it would be nice to have access to any stored information (Notes, Schedules, History, etc.) perhaps as icons on the screen. The ability to color-code the screen for incoming calls. In other words, allow the user to assign colors to contacts (similar to color-coding of contacts by category in Outlook 2007.) Thanks! Michael

$100 adding more controls to the Smart Phone API. Currently, I can not port my Windows Mobile 5 Pocket PC application to the Smart Phone because the Smart Phone API doesn't support tab pages or button controls. I realize Smart Phones do not have a touch screen to select between the different tabs, but a Smart Phone user could scroll to a Tab Page and then tap the Enter Button to select between the different tabs. Thanks, John

Definitly data calls. The ConnectionManager can be really improved. For me and my customers it would be very important to create specific connections (UMTS, GPRS etc.) and also to close them, hen I want them to close and not, like it is now that it get's closed when the ConnectionManager "thinks" when it is the best time for.

API for reading IMSI and IMEI from the radio module in some standard format. Currently OEM's return whatever they wish. It should also be possible to read IMSI and IMEI in offline mode. This is possible in Symbian phones. Zlib compression/decompression API. Simple API for handling menubar, which works identically in PPC and Smartphone. Status codes to HTML control (connecting, sending n%, receiving n%, error) without using the complicated COM interfaces. API for getting bitmaps used in MessageBoxes, menu/list background etc.

I know it might sound silly but I'd like the ability to adjust the size of the contact picture that I see when accepting an incoming call and on the call-in-progress screen. (As in making it bigger.) Right now the image is tiny and that really annoys me. Every other phone I've used, the contact picture is big so I can see it. I don't care much about playing a video but at least give the option to show a bigger image. People want to personalize their phone and make it easier to recognize who is calling. It's all about the little things that boost perception.

!!! PROPER WAY OF (PRIVILEGED) CODE SIGNING !!! If you want more phone applications your first step should be to change the rip off scheme for code signing. Just do it like EVERY other code signing is implemented on the market. Verify the developer/company (you even can ask for money for this process) and then give them the power to do as many signatures they want (even a time based model like developer can create signatures within one year only would be better than the current model). Just answer yourself this question: Why the developer wants to pay for every change/update the phone gets which make adaptations of the software necessary?

I would like to see better integration with the camera and audio recording. The managed APIs for photos, videos, audio and the gallery are an OK start, but overall do not provide for a smooth flow from app to these OS/device functions. Also, having device metadata in the media files for all new devices should be provided. Providing APIs to access and update this metadata would be useful too.

Why on earth were Notes removed from the mobile version of Outlook? This makes it impossible to sync desktop Outlook with a portable device. Many many people simply want a Razr-sized phone that can sync with Outlook. Period. Year after year, vendors ignore the fact that many people simply want their PDA-type information with them for reference, NOT for intensive updating. My Palm PDA has what, 8 megabytes of memory, and syncs perfectly with Outlook. Yet my Motorola phone, with half a gigabyte, doesn't even have ADDRESSES in the contact list! Nor does it have tasks. Or notes. Or any way even to sync the paltry data it supports with Outlook CORRECTLY. So here comes Windows Mobile, currently supported on a whopping ONE clamshell phone (Pantech PN-820 at Verizon) since Cingular discontinued its 3125. And what do we find? Microsoft has removed Notes. Come on, guys, this is a simple block of text. Why on earth remove it? And in case you can't envision scenarios that come up for things like Tasks and Notes on a phone, here a two real ones:

I keep my grocery list as a task category in Outlook. Under "Groceries", each item is a task. If I'm driving home from work and decide to stop at the grocery store, I have my list right on my phone.
I keep all my recipes as Notes. I'm on a ski trip in Tahoe, and we decide to cook in one night. No problem: I have my lasagna recipe right here on my phone, so we can pick up the ingredients at the store. Besides situations like these, the other obvious use for a Windows Mobile phone is a simple backup for your desktop Outlook. So why make that impossible?

Extension commands in the phone UI. Allow adding buttons to the dial pad. Allow adding menu commands in the call history. One missing feature in the call history which I can find in every phone around is to add the incoming phone number to an existing contact. I have to create a new contact, copy the phone number, delete the contact, and paste to the existing contact. This is a pain.

I'd like to see two things: First, an API call to get the current time from the cell network. This is useful for apps that want to sync with whatever timezone the phone finds itself in, i.e when I land in a new city and turn on the phone, I'd like to be able to get the current time in that city from the cell network. Second (peripherally related to the telephony API), higher performance access to the soundcard. Currently, I need to go through delegates to the native Wave API. On constrained machines, this can be too slow for doing sample read and writes every 20 ms for example. It would be good if the Wave API were exported through a managed API that had better performance.

$100:Phone service API! Encourage manufacturers to allow someone to mix and match the OS, phone parts, network service and the applications. Currently, phones (smart or PDA) are not available until after the phone company lag time. Once they deliver their phone with their service it seems it is 2 or more revisions behind current technology (how long did phone companies only deliver a rotary phone). Then if you want to upgrade your OS you have to wait until the next phone comes out (often a year after phone company lag time). I pay Phone company for their service and a card or code I can load on any phone. Some GSM is like this but it's the exception not the rule with major US carriers. Thanks, Stephen

Tighten what the cell providers can do to break the OS level operations. Having worked directly with providers I can say they have too much lee-way in ruining your OS and giving it a bad name. The separation between kernal space and user space needs to be cleaner i.e. bad Motorola apps. or versions coming out of platform builder shouldn't be crashing a phone. The OS needs to be tight with a light layer of customization. Windows Mobile is paying the price for this flexibility. No one says, "My Motorola [or Samsung] crashes" because they refer to it as Windows Mobile.

What are the things you wanted to programmatically do on the phone system, that you weren’t able to do? 40$ - I want to receive a notification when users make an outgoing call and I am able to allow or disallow the call before it is really dialed, and I can change the outgoing number before it is dialed. 30$ - I want to record the voice communication and I am able to play voice clips to remote party. 30$ - When a call is received, the Phone App does not dispaly its UI before I finish my processing.
From the things that you were able to do, what were the pain points? I have to do API hooks to prevent the Phone App from displaying its UI when a call is received.
What kind of phone (dialer, makecall, incoming calls etc) related apps do you write, such as answering phone call and replying to sender with SMS when in a meeting ? Calls and SMS firewall.
What kinds of phone UI extensibility are you interested in, such as changing the color of the text in the accumulator. I don't care.
What kind of technology (managed/native) do you primarily use for writing your apps? Native.
What type of phone related notifications (from the notification broker) do you wish your app could receive? Incoming calls, SMS and outgoing calls, SMS.

$ 50 - Make all APIs maanged. Irrespective of what API, make it managed $ 20 - Notifications for incoming and outgoing calls. Enable event hooks so that additional functionality can be integrated e.g. answering machine or voice mail $ 20 - Access to IMEI nos and cell tower information $ 10 - Access to broadcast information. Most Nokia models list the area one is in but WM phones don't seem to do that.

From the things that you were able to do, what were the pain points? Support a device that had broken TAPI support (for making calls). I wish the TAPI support were more complete among all manufacturers.
What kind of phone (dialer, makecall, incoming calls etc) related apps do you write, such as answering phone call and replying to sender with SMS when in a meeting ?

My suggestion is simple and frankly amazing that WM does not have it yet. Extension Dialing so those of us with extensions stored as "work" in the phone directory can easily call into our companies. Here's how it works: I am replacing a blackberry and my contacts for internal people within my company utilize an extension number for internal dialing. In order to reach someone directly one dials a long distance main number first and waits for a tone. At that point the extension is dialed to go straight to the person's desk. The blackberry has a setting where you tell it the main number for these types of calls along with the default length of extensions. THEN... whenever you dial a number of that length it automatically dials the main numer and waits for you to click the track wheel (for it to dial the extension). Also, any number in the phone book with an "x" infront of it is also handled as an extension (same way). Adding this in a global way into the phone would allow us to set the phone up for "what to do in the case of extensions" I would not want to have to go back and edit every person in my address book (within my company) and add the main number along with a pause. The better way is to just have this setting like blackberry does. Then anyone within your company can be reached by dialing the extension. People at other companies could just be stored with their main number along with a "x" followed by the extension. The phone would interpret the "x" to mean wait and prompt the person to click (or something) to have the phone dial the number following the "x"

My Absolute #1 Item is:
The ability to dial a corporate extension from the address book. Explanation: this would be of big benefit for people that work for companies where people are reached by dialing a main number and then (once getting through) dial an extension. My address book has many people stored with their extension in the "work" phone number field. In my blackberry I set the default extension length to be 6 digits. I also set up (in one place) the number to dial for accessing corporate extensions. This is VERY different from editing 400 phone records to insert the main number and a bunch of pauses. The phone knows that when I dial a 6 digit number - to dial the number stored for corporate extension dialing and then prompt me for when to send the extension. ADDITIONALLY - since not all extensions conform to 6 digits (either different length extensions at my company or others in my address book at different companies) the phone knows to do the same whenever you dial a number with an "x" in front of it. ADDITIONALLY - if you have anumber stored in your address book as say 555-555-5555 x123 the phone knows to dial the 555 number and wait until you tell it to then dial the 123 extension. This is not rocket science and I frankly cannot believe it has not been addressed thus far. Asside from having to edit every existing address book record to add the main work number and a pause or two, every new name I bring down from the corporate directory would need to be edited the same way. Today, all I do is bring them down on the fly and call them. Worst case I have to edit to add an "x" if they do not have a 6 digit extension. Hope to see this addition soon - or - perhaps some genius could write an add on program. I know I would buy it and frankly spend more than the typical short money for this one!

Mapi synch of sms/mms message - it is ridiculous to have to manually back-up these messages, when they should be visible and shareable like any other messages, both for businesses and personal usage. Proper synching of notes. Ability to add number from received SMS/MMS to new contact or merge with existing contact Ability to merge number from call history to an existing contact Ability to copy a number from call history so it can be pasted into other apps Multiple phone numbers and multiple mobile numbers - in the same manner as the existing ability to add multiple emails. Ability to store and dial extensions, without having to dial n main switchboard number (blackberry has this). (- as suggested by Paul above.)

First of all with VC++ 2005 SP1 and mobile sdk is impossible to debug a dll, error with PDB. Anyway for this post, for the future phone APIs, i'v found some bugs and problems:

Issue when Answer to an incoming call with TAPI (or RIL), add a missing call into the log and show a notification about that. (keybd_event is to limitated)
Manage call log (adding and deleting) improvments, Phone api permit only to read it.
Unlock screen can't have the related api
Switch from internal speaker to loud speaker (during a call) need the api,
Wi-fi enable/disable/find must need more msdn help
cprog.exe interface are needed, the 5+ dlg and the notification are undocumented.
Hooking are undocumented such as CallWndProc or CBTProc.
