I'm trying to test srst feature. I have one 7905 and one 7960 in branch office, and one ccm4.1(3) in central office, I enabled srst feature in branch router. then I use access-list to deny all port 2000 packet going to ccm, after a while, 7960 switch register to the branch router successfully, but 7905 just stop working. I checked 7905's setting and found it has only one Callmanager setting, but 7960 has two: one is for the central ccm and another one is for SRST which specified to the branch router. That's why 7960 succeeded and 7905 failed.

but, in my ccm, 7960 and 7905 are using same device pool which enabled srst feature, why can not 7905 get the srst information from ccm?

my 7905 is using sccp version 6.00.00, my 7960 is using sccp 7.1(2.0).

thanks for any responses.

you can check which firmwares are compatible depending on your SRST version:

Cisco Unified Survivable Remote Site Telephony (SRST): All Versions
