Summary:                    Asterisk generates a BYE after 15 minutes or more
consistently on trunk calls
Description: 
All calls I have made from phone to asterisk to phone works fine for long
calls. No problem. But when I make a call from phone to asterisk to sip
provider to asterisk to phone, I notice asterisk generates a BYE at random
time, usually after 15 to 20 minutes. I've never seen it happen before 15
minutes. I've done sip debug and sip trace, neither show any other packets
except the RTP traffic working perfectly, then all the sudden asterisk
sends a BYE sip packet and the call drops. This happens when calling a PSTN
number as well, or another asterisk server over IAX2.

This problem is related to issue 15270. After changing udptl=yes to
udptl=no, it works fine. I'm not sure why this has anything to do with non
t38 calls to pstn, but it does. Maybe this issue should be linked to 15270.
