Cisco recommends that you perform this verification outside of business hours as it will cause an outage for your remote branch if SRST is not triggered.
1.      Test the SRST configuration:

You can either take down the WAN interface or add a static route to null 0 for any ip packets coming from Unified CallManager:

ip route 171.69.103.225 255.255.255.255 null 0

Caution: Use extreme caution when using the above static route. The impact of this can affect other sites depending on your IP routing environment.

You should see the following messages appear on your remote branch router (in this configuration example, RTP router):
2.      *Nov 1 06:16:34.707: %IPPHONE-6-REGISTER_NEW: ephone-2:SEP000BBEF9E85E
3.                           IP:10.10.10.14 Socket:2 DeviceType:Phone has registered.
4.      *Nov 1 06:16:54.375: %IPPHONE-6-REG_ALARM: 15: Name=SEP00115C0E5EDA
5.                           Load=7.2(4.0) Last=CM-ICMP-Unreach
6.      *Nov 1 06:16:54.375: %IPPHONE-6-REGISTER_NEW: ephone-1:SEP00115C0E5EDA
7.                           IP:10.10.10.12 Socket:1 DeviceType:Phone has registered.

The statement "ip route 171.69.103.225 255.255.255.255 null 0" was just an example.

You would replace this with ip route x.x.x.x 255.255.255.255 null 0
with the x.x.x.x representing the ip address of your callmanager server.

If you have 2 callmanagers you will need a statement for both.

This effectively stops the phones from being able to reach the callmanager which is what should activate the SRST functions.

you need to add this route in the remote router that you will be testing srst with.  When you add the route their the remote router cannot reach callmanager but should still be able to reach everything else.
