Re: SRST fallback to CallManager bandwidth requirements to rehom
The number of IP phones and line appearances supported in Survivable Remote Site Telephony (SRST) mode at each remote site depends on the branch router platform, the amount of memory installed, and the Cisco IOS release. (For the latest SRST platform and code specifications, refer to the SRST documentation at Cisco.com.) Generally speaking, however, the choice of whether to adopt a centralized call processing or distributed call processing approach for a given site depends on a number of factors such as
IP WAN bandwidth or delay limitations
Criticality of the voice network
Feature set needs
Ease of management
If a distributed call processing model is deemed more suitable for the customer's business needs, the choices include installing a local Cisco CallManager server or running Cisco CallManager Express on the branch router.
