I guess the first point of call is compatibility. For starters I cannot see the SRST option under device/phone/product specific configuration. Any explanations?
I have searched and located a huge volume of documentation which I would like to filter out tbh :-(
The goal is to enable fallback on H323 gateway (2821 c2800nm-spservicesk9-mz.124-6.T8.bin), with a mixture of 7940G and 7960G's.
kindly point us to the need-to-knows and i'll take care of the rest.
Not sure if you are looking for configuration of SRST or compatibility.
As far as configuration of CM you need to build the SRST Reference and assign it to the device pool the phones are using.
As to the GW confgiuration and compatibility you can find everything here:
