I have a customer with one site has 1,500 IP Phone users. What would be the ideal Voice Gateway selection with SRST Support. The phones' primary Call Processing would be a subscriber located in a Data Center, and if the link goes down then SRST will kick in.
3845 can support up to 700 SRST Phones, and I was thinking of deploying (2) 3845 with IP-IP Gateway feature with load balancing between those two and at least half of the users will be active if one of the gateway fails.
Do I need to go for higher family of Voice Gateway such as 7200/7600 or AS5400 etc.
Cisco now offers CUCME/SRST bundle. I don't see any benefits of CUCME/SRST with Centralized Depoloyment. Is there any benefits?
