Hello Dears,
we are facing a situation here where IP calls from remote site is disconnected after 5 minutes when it is to otehr remote site
Setup:
Site 1 (phone registered on CCM on site 2)---- site 2 (CUCM 7 )--------- IP trunk ------ site 3 ( CUCM7)
When calls from site 1 to site 3 >>>> disconnects after 5 minutes
When calls from site 2 to site 3 >>> no problem
When calls from site 1 to site 2>>>> no problem
is there any parameters on the CUCM limit the call duration ?, is there any bug ?
Thanks & BR

Without being able to get the full picture of the network topology, I'd offer the following comments to get started here:
1) There is no limit on CUCM call duration that would cause calls to cut off at 5 minutes.
2) You need to fully vet the routing between all sites - particularly between Site 1 and Site 3 as if there is a pretty close 5 minute mark on disconnects, you could have some issue with flapping/reconvergence of links within the network. It's hard to sometimes track this down but I would definitely focus in a solid effort there.
3) What phones, what firmware, and what codec is used between Site 1 / Site 3, Site 2 / Site 3, and Site 1 / Site 2?

Hello Hailey,
First of all thanks for your reply , second I have developed a troubleshooting plan to isolate the problem and I found that problems related to the IP range assigned to Site1 (once using any other range problem disappear).
so I will check the routing, the FWs between the sites and feed back.
Thanks again.
