Asterisk 1.6 reinvite

HI All.

After 15 minutes of conversation asterisk sends a signal “reinvite” and stop responding. The conversation is interrupted.

Please help to solve the problem … Version:

sip.conf

[general]
context = default; Default context for incoming calls
canreinvite = no
directmedia = no
allowsubscribe = no
transport = udp
allowguest = yes; Allow or reject guest calls (default is yes)
bindport = 5060; UDP Port to bind to (SIP standard port for unencrypted UDP
udpbindaddr = 0.0.0.0
; bindaddr = 0.0.0.0; IP address to bind UDP listen socket to (0.0.0.0 binds to all)
bindaddr = 217.23.132.83; You can specify port here too, like 123.123.123.123:5080
; tcpenable = no; Enable server for incoming TCP connections (default is no)
; tcpbindaddr = 0.0.0.0
udpenable = yes
srvlookup = yes; Enable DNS SRV lookups on outbound calls
useragent = prostoy.ru; Allows you to change the user agent string
videosupport = yes; Turn on support for SIP video. You need to turn this on
rtcachefriends = yes
rtupdate = yes
rtautoclear = yes
disallow = all
allow = g729

THX ALL!

This is typically the result of a problem in the peer’s handling of session timers. An actual SIP trace would probably make this clear.
