@all, I have locked this thread, because this is an old post. The more recent thread where we announced the 1.0SDK port is still open for comments. All responses to comments will be posted there. Link for that thread: is here

Hi,
has anybody tried this on an actual device? I have been trying it on a G1, but an unable to get the G1 to register with the server. I have tried both via the 3G data transmission and via a wifi connection, I have also tried gateway solutions with my sip provider that support nat translation.

Any suggestions gratefully recieved and would be happy to post feedback on the setup once i get this working.

Regards

Mark

Hi everyone,

We are trying to incorporate instant messaging service in this UA. We are able to send messages successfully to the other end, but not able to receive any. I guess it’s because incoming messages are intended for the SIP UA running on the emulator, but they don’t get there, they get stuck on the machine as it doesn’t see any application running on that port because UA is not running on the machine, it’s actually running within the emulator (I see ‘Port Unreachable’ in the WireShark logs). I think for the same reason the UA doesn’t take incoming calls. I tried using adb for port forwarding, but it didn’t help.

I would really appreciate if you could provide any help on this.
Thanks in advance.

It looks like this program won’t work any more thanks to Google removing javax.sound.* in the 0.9 API core library:
http://code.google.com/android/migrating/m5-0.9/changes/changes-summary.html

The new release of this code that is works with the 1.0 API says:
“This release does not include the RTP stack as it is already a part of the released Android source code…”

There does not appear to be an RTP stack built in to Android; someone please correct me if I am wrong.

@Neo,
sure Registration and all non-voice related functions will work (IM included)

hi,
However, for basic SIP registration, I still have no idea why it is related
to audio capture. Without multimedia transmission, how come basic SIP function,
such as instant message (only text part) cannot be supported in emulator.

Any SIP command could be performing in Android or not without audio part?

many thanks

Hi Thomas!

For registering SipDroid on the Proxy, simply change the domain/realm from the configuration screen. Reload the client and you should be good to go. We have tested proxy based call routing using Brekeke and it was seamless.
