Is possible, change the Timers for the Keepalives on SRST SIP, from 2 minutes to any other value...?
I think you can change the value , by defualt timer for SIP it is 120 Sec you can make it any other value like 60 Secs etc.
So on CUCM go to service parameters -- > find SIP keepalive timer -- > and make it 60 sec.
Please rate all useful post!!
