Hi

I have two cisco 3845 routers with CME installed on them.I made a call through WAN from one phone to another.Then i took out the WAN connection and the call went through PSTN.

My question is SRST is used for PSTN fallback.Without SRST why do you think the call goes thru PSTN.

can someone expalin the difference between CME  and SRST exactly.
