Good Morning Group
I’m wondering if I could trouble you for some of your valuable time to help me resolve my cme-srst issue that I currently have.
We are running CUCM 8.5.1 and we are trying to configure our Cisco 2911’s to use SRST, now the Router is registered with the CUCM as shown below.
Primary Registered 172.28.140.8
First Backup Backup Ready 172.30.213.75
Second Backup Backup Ready 172.30.213.15
We are using VRF’s in our network and understand that MGCP is not VRF aware, for this reason we used another port on the Router and used static Routing to allow us to connect and register with our CUCM.
When I drop he WAN link our phone does not fall over to SRST mode, looking at the phone itself SRST is shown in the Unified CM configuration as one of its fall backs.
Below are our configs which I’m hoping will show you what I’m missing to get SRST working.

Hi
If you shut down the WAN link , may be that cause problem. I requested from you to do the below :-
ip route 172.28.140.8 255.255.255.255 null 0
ip route 172.30.213.75 255.255.255.255 null 0
ip route 172.30.213.15 255.255.255.255 null 0
This will down the connection to your CCM , and we will get more information.
Thank you

Hi
i have a question for SRST configuration on CUCM , do you have configured SRST on your DP.On Device Pool configuration , you will find route group (this should be assign tou your registered MGCP router which will be used for SRST) and on srst down select use default gateway and 30 to monitor,
Thank you

we use VRF so your routing statements will not work.
The Dp had the correct information also
Thanks for the reply
