I have seen a couple of open tickets on the 30 min session reinvite issue. This 
causes the media gateway to respond with a 488 and then a disconnect. 
What are some possible configuration options here ? It happens only on outbound 
calls 

polycom 450 frimware 1.3.1 
sipxecs 4.04 
asterisk / sangoma (media gateway) 
not nat 
trunks built with sipXbridge as sip trunks 


At 30 min sipxecs sends a sip/sdp invite to refresh the session ( i guess ... i 
thought this was handled with and update ??) in which the media gw responds 
"not allowed here" 488 

sipxecs says Bye 
gw says ack 
gw says bye 

call is over .... caller is mad at me :( 


Warm Regards
