Short of failing the WAN connection from the phones to the Call Manager - what all can you do to verify that SRST is ready to kick in in the event of a WAN failure?  Using CUCM 7.1, 2811 ISR in the remote office.  Thank you.

You can test with a single phone if it is in the same subnet as the SRST router.

Change the default gateway on one phone to a bogus IP adress. The phone won't be able to see the CUCM and should then fail over and register with the SRST. Once you confirm that it works with SRST then change the gateway back and it should register with the CUCM again.

Thanks a good idea.  I am remote however and the phones register via DHCP.  Anything I could run on the router or CUCM to get insight into SRST readiness?

Are the phones in their own VLAN?  You could put in a deny for that VLAN to the CUCM on the router.

For example. all our phones are in VLAN x.x.100.x

You they are all on one vlan.  And indeed I could fail all the phones say pointing route to null for the CUCM.  But I am trying to just do check without failing.  When I am out there in a couple of months I'll do just that - route to dev null and let the chips fall where they may.  But for now I'm looking for some commands that would show that the phones will be ready to go into SRST mode if the WAN went down.

Oh now I think I understand:

http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/admin/configuration/guide/cmesrst.html

About halfway down is a section on verifying SRST.
