I am using CVS - It is possibly the nature of the refusal from Asterisk 
that is causing this unexpected state - I will try and reproduce it, and 
sent you details of the SIP exchange that occurs if that proves useful.

No, CVS it is, and this file does look interesting (I had not noticed it 
before) I'll see what I can provide for you. The only immediate item of 
interest is the attempts to use "SUBSCRIBE/NOTIFY" which asterisk is 
refusing (not yes implemented AFAIK).

Yes, I am on the LAN, and have disabled all the NAT features - When no 
audio was received, I saw 0Kb/s on the status line, and IIRC this was 
reflected on the "i" screen. I'll repeat the experiment for 
verification, and do network traces if possible.

This seemed only partially successful - I'll experiment further and 
report back. Perhaps an attempt to "ESC" out of MythPhone during a call 
could prompt for "hangup", "hangup and exit", or "cancel" ?

I might even be up to coding that one myself ;-)

Okay I confess - On-hold music is a usefult test of connectivity to 
asterisk, and of audio :)

Thanks for the pointers - I'll try and put a coherent package of results 
together for you and report back ASAP.
