Hi everyone,
my customer has two routers 2921 and he asked me configure high availability between them, i configured HSRP; in CUCM i set up SRST reference to IP virtual default gateway, unfortunately this configuration doesn´t work because when ip phones can not reach CUCM, they don´t get registered with SRST routers. TAC told me that HA SRST - HSRP don´t work with IOS 15.They gave me no an alternate solution. How can i solve this problem?
I appreciate your help.
