Thanks Tony. Its possible that the phone stops sending RTP stream (but it certainly is receiving some!). How do I get Asterisk to stop caring whether it receives RTP or not?
Yes there is a NAT between the phone the the Internet. The Asterisk server doesn't have NAT though. I'll try to find out what I can from my limited RTP expertise. I appreciate the response and the hints.

Can you user Ethereal or similar to find out whether the phone stops sending the RTP stream to Asterisk when it is muted? Is there any kind of NAT gateway between the phone and Asterisk? If both of the above are true, it might be possible that the NAT gateway's session mapping for that stream is timing out. Or perhaps Asterisk decides to hang up the call if it doesn't get any RTP for a certain length of time. Just a couple of ideas to try. If the phone is still sending RTP when muted, the stream presumably contains perfect silence. I don't know if that gets detected anywhere.
