[Blink] 0.18.1 Audio fail with log

Hi Dean,

I have a Gizmo account and a Nexus One with Sipdroid and I could  
reproduce the scenario.

A. I know why the call terminates which happens after 15 seconds  
actually. The reason is the Sipdroid ACK message is broken and does  
not reach Blink. As a result Blink terminates the session with BYE. I  
found your particular call here:

https://secure.dns-hosting.info/CDRTool/sip_trace.phtml?cdr_source=sip_trace_thor&callid=965472361855%4066.25.30.183&fromtag=z9hG4bK52005130&totag=8Xw-U.dm.gk20Oar6Js6y0oHuMm2G7e0&proxyIP=85.17.186.7&action=toggleVisibility&toggleVisibility=1&public=1

As you see at Packet 11/33 Blink sends OK with Contact Header:

Contact: <sip:iczuvkrx at 66.25.30.183:65315>

Sipdroid must sends its ACK back to the same contact but instead it  
sends it to the SIP Proxy address:

ACK sip:iczuvkrx at 85.17.186.7:5060

Which has nowhere to go further and is dropped in the SIP Proxy.

So either Gizmo 5 SBC or Sipdroid are broken, the ACK is wrong and  
Blink has not fault.

B. I could not reproduce the crash though. Can you send the Crash  
report please?

Adrian
