Database Info

how can i intercept a phone call?

what i want to do is to automatically add a specific prefix to all outgoing calls made, for the purpose of saving calling fee in my area. for instance, i want to add 1234 before any call number, whether it's from call history, contact, or any other sources.
im a .net developer, but i didn't find any managed library that can intercept a phone call and make modifications to it. i also explored the TAPI a little bit, it appeared to be able to do the work for me. but the problem is i've no idea of c++ programming.
so is there anybody here who can help me on how to wrap these native methods into managed counterparts?
any/other clue would be appreciated.

Take a look at Google Voice. Perhaps that might be simpler to use to save money on calls?

Hi,
try with Settings > Connections > Advanced > Dialing Rules
I think you can setup a profile that fit your needs.

doesn't work. and i don't think that setting is for phone connection.

actually i've changed my idea to developing a separate application to access call history and contact. and then when call button is clicked, use the managed Phone class to dial out. this still needs native dll as to accessing the call history. but this seems to be more practical than intercepting outgoing calls.

Not sure if this is exactly what you want, but I use this with my Googlevoice configuration to make free calls. Here's how I have it set up:
1. Installed iDialer
2. Installed configuration CAB that I built through the iDialer website
3. Click the phone icon within iDialer to set it to "Ask" which service to use.
4. I also have installed iContact, so I then go the contact I want through iContact.
5. I select the number for that contact that I want to dial (Home, Work, Mobile, etc.)
6. My phone brings up a pop-up asking:
-Alltel
-GoogleVoice Internet
-GoogleVoice CallingCard
7. I select what I want and it dials that instantly.
This works VERY well for me, and I am able to use my callingcard for out-of-network calls, and Alltel for quick in-network calls.
Hope this info helps!

thanks for the details.
i have 2 queries b4 actually trying it:
1. does the phone call get available via the network? if yes, then it's not applicable for me, cos i'm using gprs which is slow if i want to transfer voice.
2. i checked out google voice and found that it only supports numbers in US. true?

Moved as not software release or development.

sip2sip.info changing voicemail

I have successfully set up my Droid for Sip calls both in and out. I am using sip2sip.info as my provider. The voicemail messages states something like "Box number 1000000 is not avialable now" then allows for a message (though unless you know you can leave a message it is unclear. The instructions on the site say to dial *70 to find voicemail options (and I would think there I could change this) but when I try dialing *70 the call won't go through. Can someone help me with this - do I have to enter something before the *70? I am dialing it from the Droid. Oops forgot to mention I am using Sipdroid on the phone.
I am sorry if I am posting this question to the wrong place, but I found a posting on this site that was excellent in helping me set up my Droid to use sip2sip, pbxes and ipkall so hopefully someone can help with this.
Thanks

[Q] Stop incoming calls while tethering?

Is there a way to block or foward any incoming calls to voicemail so it won't drop my internet connection while tethering? Ive read about looking for DDTM mode in call settings but i dont seem to see anything like that in the Cyanogenmod. Maybe this for some other type of mod or even Sense. Any help would be appreciated. If this is the inappropriate thread to post this to, I appologize.

im tired of being nice...first READ THE FREAKIN RULES. DONT post in the wrong section. How does this qualify as a development thread??? look at the top of this forum and loook at the sticky threads!
QUIT BEING RETARDED AND LOOK AT THE ADMINS THREADS! THEY ARE PUT THERE FOR A REASON!

EDIT*****
My apologies i did see that you posted about the thread not being in the right section. This should be placed i nthe Q&A section i posted above at or the Cm6 thread. Sorry for being so harsh its just no one reads rules or follows and type of order around here and im tired of it.

i'm not aware of any way to stop the calls, because if u shut off the radio, it shuts off the data too (but u can shut off data but leave phone...)
I haven't seen any roms with a work around either. So i suggest you tell ur people just to text you first and u can call them back. haha.

Yep. DDTM is in the programming. Make sure your ROM has an HTC stock dialer and EPST (any simple Sprint ROM will work).
Dial ##3282#
Enter your MSL (you're responsible for retrieving this)
Go to "Advanced"
Scroll down to DDTM
By default, it's off. Enable it
This by default should block all calls when the data session is active. I'm not sure how it handles dormant data connections.

Help Me!!!!!!!

I have a problem with a nexus s .... The problem that shows up and hooking the 3G, but it does not receive incoming calls and outgoing ...... to point out that being a phone from a vodafone contract already closed .... and that can block the IMEI of the phone will block the calls. Let me know.
thank you.

This is in the wrong section, there is CLEARLY a forum called Q&A.
Post there instead, this is the development forum.

Post your questions in the Q&A sections in future please.
Also any talk of undoing a IMEI block or changing an IMEI will get your thread closed.
Changing IMEI's is illegal in most countries.

If a person wants to switch providers, they'll block the IMEI? It 's the first time in history

[Completed] Unwanted texting prefixes and "Yi Dialler" prompts before making calls.

Hello all,
I'm unsure about where to post this issue I am having with my handset. Let me explain a little about what is going on, and maybe someone can redirect me to where I should post the full details and hopefully get some answers
Have a Huawei C8813 Handset from China. It was payment for a computer job I did some time ago. I suspect it was a contract phone of some description, however it was completely wiped when I received it.
I had to perform some build prop edits in order to get it working on 2 Degrees here in New Zealand. These involved (ro.cdma.home.operator.numeric=53024) and other related lines.
The issue I am having at the moment is that when I receive calls from other cellphones in New Zealand, they come through with no International prefix (this is fine, and desired). However text messages I receive from NZ cellphones come through with the International prefix. So if I were to receive a call from 022022022, it would come through as such, but a text message from the same number would appear on my handset as +6422022022. This causes me to attempt to enter both the prefixed and non prefixed numbers into every entry in my address book. Text messages will send fine to either the prefixed or non-prefixed number, but this causes message thread separation (undesired).
Further to this, if I make calls to a non-International-prefixed number (a local New Zealand cellphone) eg 022022022, I get a dialog up titled ""Yi Dialer" (China +86)" with the following options: "Call China (International Roaming Call)", "Call China (**133 call back)", "Call other country", "Call local". Obviously the call goes through fine if I select "Call local". However, if I put the international prefix in front of the number for NZ (+64,) calling a number in NZ, it bypasses "Yi Dialer" altogether and just makes the call eg: +6422022022.
I have searched the internet far and wide and can find very little related to "Yi Dialier" (or "easy dialer" if translated from Chinese). I have checked out all of the stock applications that came with the phone and none appear to be related to dialing.
I am interested in perhaps a build.prop or similar setting that may erase this issue and make the phone believe it is based in New Zealand. As far as I can work out, the handset thinks it is roaming all of the time, when in fact it is not. There is no convincing it of this through regular Android settings with regards to the carrier or cellphone network.
Any help or direction with this would be greatly appreciated. I am happy to provide screenshots and exact build.prop edits I have done to make the phone operate here in NZ.
Thanks in advance,
Mike
