Android Question i can not hear remote ring using Sip library

Hi, I'm using your example to create a sip-client, I have a problem, I do not hear the remote ring or the operator's messages before sending to voicemail, but if the person answers the call, the audio is full, i ear the other person and i can to talk without problems. How can I get the audio before the call is answered? Thanks you.

Thanks for answering, I already tried that option and I get the following error:

CallError, ErrorCode=-4, ErrorMessage=mPeerSd = null

Then, the app stops working but the call continues until the other party hangs up.

 

I downloaded your example and replace the following:

'Register with the VOIP service
Sip.Initialize2("SIP", "sip:zzz@iptel.org", "xxx")

by: Sip.Initialize2("SIP", "sip:5003@192.168.10.110", "Rg123456")

and..

CurrentCall = Sip.MakeCall("sip:8355@ideasip.com", 30)

by: CurrentCall = Sip.MakeCall("sip:573108712160@192.168.10.110", 30)

and Runs, touch "Make Call", in few seconds my mobile phone rings, but in app not hear, then, if i don't answer my mobile, in the app NO hear "voice mail system, will have cost from this moment, please Leave your message after the tone" only hear when call is stablished (the tone has been played) and minute is billed and voice mail operator's play a message for i record a message.
