Hello All,
Gateway: ISR4321/K9
IOS-XE Version: 03.13.04.S
IOS Version: 15.4(3)S4
I am trying to test the SRST failover of an ISR Router, but after I cut the connection to CUCM, the IP Phones never actually register to the Router. See below for configuration...
CALL-MANAGER-FALLBACK:
call-manager-fallback
secondary-dialtone 9
max-conferences 2 gain -6
transfer-system full-consult
timeouts interdigit 5
protocol mode ipv4
ip source-address 10.18.2.1 port 2000 !--> 10.18.2.1 is the Voice Vlan IP Address on ISR4321
max-ephones 12
max-dn 48
default-destination 4019
I also configured a TEST-DP and a TEST SRST Reference on CallManager (*v8.6) and applied that Device Pool to the H.323 Gateway I added to CallManager for this ISR Router. Is there anything I am missing that also needs to be configured to have the Phones Register to the Gateway? I tried running "debug ephone register/state" but no information is printed to the logs when the connection to the CallManager is lost.
SRST Reference Configured on CUCM:
TEST-SRST
Name: TEST-SRST
Port: 2000
IP Address: 10.18.2.1
This SRST Reference was then applied to the Device Pool I created which is what I set the H.323 Gateway's Device Pool too.
But, for some reason it doesn't seem like SRST is working at all. We have the FL-SRST and FL-CME-SRST-5 Licenses.
If anyone has any thoughts or suggestion, it would be very much appreciated.
Thanks in Advance,
Matt

It is under SRST configuration at CUCM. You don't need necessarily remove call-manager-fallback; it is just not needed. Just add SIP-SRST as suggested in the URL before.

Have you configured the below.
RemoteSite(config)# application
RemoteSite(config - app)# global
RemoteSite(config - app -global)# service alternate default
RemoteSite(config - app -global)# end
See if this helps

As your logs and dial-peer voice 10 pots suggest you are forwarding the starting '9' to the provider.
Try this:
dial-peer voice 10 pots forward-digits 10
If needed, you should also add more pots dial-peers (eg. for emergency, local, international calls).
