I am trying to test a SRST fail over scenario with a few phones(7941,7961 and 7912) When I force a fail over to SRST the phones all register with the Voice Gateway but only the 7912 has its line intact. The 7941s and 7961s are registerd with no line on the phone. Any Ideas? This is CCM 4.2 and Version 12.4(4)XC7 IOS

I am running the following:

#sh call-manager-fallback all

CONFIG (Version=4.0(3))


Version 4.0(3)

According to this document the 7941/7961s are supported.

The 7912 has different

way the phone's user interface is

handled compared to the 7960

Fist, Try upgrading the load on 7912

Also, can I see the config for SRST router
