How to Configure CUCME in SRST mode with CallManager 6 , 7?
SRST basically is very useful feature of Cisco CallManger to support remote site phone in centralized network during periods of fallback. CUCME in SRST mode enables routers to provide basic call-handling feature for IP Phones if they drop connection to remote primary and secondary CUCM or if the WAN connection is down.
CUCM Configuration:
Step 1: (First complete all Routing)
Step 2: (CUCM Configuration)
- CUCM Admin Mode -> System -> SRST -> Add New -> Name ="SRST-SITE-1" -> Remote Site Gateway
IP Address = 102.168.100.100 -> Save
Step 3: (Create Device Pool)
- Cisco Unified CM Administration -> System -> Device Pool -> Add New ="SRST-DevicePool-SITE-1" -> Time/Date = "Default" -> Select SRST = "SRST-SITE-1" -> Reset
Step 4: (Call Device Pool on Remote Site Phones)
- Cisco Unified CM Administration -> Device -> Phone -> Select Remote Site Phone -> Go Inside and Select Device Pool = "SRST-DevicePool-SITE-1" Save -> Reset Phone
CME Configuration:
Step 5: (SRST Configuration ONLY)
# telephony-service
#IP source-address 192.168.100.100 [CME address]
# SRST mode auto-provision all
[Some CM configuration will automatically be copied on CME e.g. ephones, DN etc
All; represents that all configuration can be seen on CME if WAN goes off
DN; represents only DN information can be viewed on CME
None; nothing will be displayed in running configuration if WAN goes off]
#SRST DN line-mode DUAL [single= single call only; dual= for dual line e.g. call waiting, call conferencing]
#max-ephone 10
#max-DN 20
[Create ephone Template]
# config t
(conf)# ephone-template 1
(conf-ephone-template)# codec g729r8
(conf-ephone-template)# keepalive 20
(conf-ephone-template)# multicast-MOH
(conf-ephone-template)#exit
[Create ephone DN Template]
# config t
(conf)# ephone-DN-template 1
(conf-ephone-DN-template)# call-forward all 2002
(conf-ephone-DN-template)#exit
[Call above defined Templates (ephone+DN) in SRST; these will start working as WAN link fails]
#SRST ephone template 1
#SRST DN template 1
