One-way audio over VPN #1096

This relates to SipDroid not working well over VPN:

Using SipDroid version 2.9, and connectiong from Samsung Galaxy S3 (ICS 4.1.2) 
over VPN to Cisco Call Manager (CCM). 
It connects without problems, and it can place calls but have one-way audio, 
only from SGS3 to phone I called ... I can not hear audio from other phone.

We detected that SipDroid is sending to CCM wrong IP address - one from WAN 
interface rather than one from VPN interface. 

I guess that if in SIP audio stream is initiated from both sides, then other 
phone will try to use that (wrong, WAN) address from CCM and thats why audio 
from other phone to my SGS3 will not work, while audio from SGS3 to that phone 
works.

Again, this is not issue about SipDroid USING wrong address/interface (it use 
correct VPN interface to establish connection), it is about SipDroid SENDING 
wrong IP address to CCM:  it sends SGS3 WAN address instead of VPN interface 
address.
