CUCM SIP Timers

[tcnagpure1]

Hi,

I'm working on SIP trunk configuration in CUCM 9.5. I want to modify the SIP timer values for a specific trunk. However, to my knowledge the change in timers is cluster wide and for all trunks. So is there a way to alter these values for a specific trunk?

Thanks

Correct, CUCM SIP timers are global, if you have CUBE you can change some timers on CUBE.

Which timers are you looking to change, and why would you not want to change them system wide?

I want to change SIP connect, disconnect and expire timers for the endpoints that has large RTT (>500 ms). Though, I don't want to change it globally, just some specific ones.

You can customize some SIP timers via SIP profile and apply the profile to specific devices, take a look at these under device-->device settings -->SIP profile.
