I have one cluster CUCM with 11.5 version
All the Ip Phone registered to CUCM
i Configured SRST reference and added to Device pool
when CUCM is Down all 78XX and 88XX ip phone registered to SRST Router,But when CUCM is goes UP again Dose not revert to That.
I configured SIP and SCCP Srst but this problem just for SIP IP phone.
there is my configuration in below
voice service voip ip address trusted list ipv4 192.168.40.29 ipv4 192.168.40.31 ipv4 192.168.40.32 ipv4 192.168.40.33 allow-connections h323 to h323 allow-connections h323 to sip allow-connections sip to h323 allow-connections sip to sip fax protocol t38 version 0 ls-redundancy 0 hs-redundancy 0 fallback none h323 no h225 timeout keepalive sip bind control source-interface GigabitEthernet0/0.150 < Interface is for srst reference in cucm > bind media source-interface GigabitEthernet0/0.150 registrar server
