CME/SRST 2900

[adamgibs7]

Dears,

i have 2 branches A and B In branch A i have 2921 series router and in Branch B i have 2901 router with CME/srst 25 licenses, branch A has e1 pri and branch B users are reaching to pstn by branch A PRI, calls are flowing through mpls between the branch A and branch B.

My question is if MPLS breaks 2901 router of branch B can become a srst for branch B users,

I have always configured SRST for CUCM but not for a CME, so may be this question is senseless.

thanks

CME doesn't have a fallback mechanism to SRST, you could buy CME licenses on that other ISR and configure CME redundancy.
