Since you can only have one SRST reference on the callmanager,


So, what you can do is have an active srst ( hsrp) router and all the phones

will register with the active srst router. If that goes down, then phones

will register to the backup.

However, you may be able to get the calls over both the PRIs by putting in 2

dial-peers, One with the low prefernce number ( hence higher preference ) to

the local PRI, and a second dial-peer with higher preference number ( lower

preference ) to the other gateway. This way, when one of the PRIs gets full,

calls will go out the other PRI. I hope your questions are answered.
