Instant hang up on Desire HD

[GoogleCodeExporter]

Calls are dropped instantly on Desire HD.
App work fine for some time and calls are OK, then suddenly call is made, but 
there is silence for both sides. After this any Sipdroid call is dropped 
immediately until device is rebooted. After reboot it works fine for a while...

What steps will reproduce the problem?

1.Make some calls, calls are OK
2.Sudenly call is made, but both sides cann not hear each other. Hang up 
manually
3.Next calls will hang up immediately after dial even if Sipdroid is restarted. 
Incoming calls are 'busy' for other party
4.Reboot device and calls are done normally again for a while

What is the expected output? What do you see instead?

-Expect to establish a call, but Sipdroid hang up immediately

What version of the product are you using? On what device/operating system?

-Sipdroid 2.0.1 beta revision 602. HTC Desire HD, Android 2.2.1 Froyo stock 
rom, kernel 2.6.32.21, update 1.72.405.3

Which SIP server are you using? What happens with PBXes?

-Used Asterisk ver 1.6, but the same happening on ekiga servers.

Which type of network are you using?

-WiFi

Please provide any additional information below.

-Codec used during call is G722 normally, but changing of codec  does not solve 
the problem. Asterisk logs are clear, no errors, just like client side normally 
ends the call. When debugged this issue, I found that hang up happening in 
RtpStreamSender.java line 343:

if (record.getState() != AudioRecord.STATE_INITIALIZED) {
Receiver.engine(Receiver.mContext).rejectcall();
...
}

Seems to me that by some reason AudioRecord object can not initialize MIC 
resources.. I hope I could help to solve this issue. Thanks.

I am having the same problems, it works just fine for some time but then stops 
to do so. The first call simply doesn't get established and everyone after that 
gets hung up instantly. Last time even a reboot didn't fix it.
Using 1und1 and pbxes via wifi.
