I would like to test SRST at a remote site using an access-list to block all traffic to back to the CUCM and force SRST at the site...The Voice Gateway is separate to the main WAN router so I propose to put the following access list on the uplink of the Core switch to the WAN router in the OUT direction...
ip access-list extended SRST
Deny ip any host 10.10.10.1 (CUCM 1)
Deny ip any host 10.10.10.2 (CUCM 2)
Permit Ip any any
interface <uplink from main switch to WAN router>
ip access-group SRST out
Does seem correct and will it force the gateway into SRST mode along with the phones? Is there something else I need to block, maybe block signalling that is coming inbound from CUCM?
