Summary:                    Picked call is hanged after 30 seconds (with BYE,
because of timeout)
Description: 
In our environment we have Cisco phones 7945G and 7965G, running SIP/TCP,
and one Patton PSTN (E1) gateway. Everything is in one LAN, one IP subnet,
no NAT or routing between them, no other traffic in the LAN.

If there is ingoing call to SIP phone, and other phone picks the call, the
call is sucessfully picked, but after 30 seconds it is ended - Asterisk
reports "Hanging up call XXXX - no reply to our critical packet".

It doesn't matter, if call is originated from PSTN or from another IP
phone. Also doesn't matter if it is picked using pickupgroup (dialling *8),
or if picked directly using PickUp() in dialplan, or if picked using BLF on
the phone.

Commented SIP debug is attached.
