Cisco Unified Communication Manager VPN Tunnel Centralized model

How to configure 2911 as gateway at remote site location? Proposed deployment model Cisco ASA5505>Cisco 2911 Router/Gateway> Cisco 3850 Switch. PSTN connected to 2911. Phones will register with Call Manager at Host site. Internal calls should route across VPN to Host site. Local and Long distance calls will route to PSTN through 2911.

Hi Jeffery,

if the 2911 router is being used for sending the calls out then it needs to be configured as H323 or SIP. It needs to be added on cucm as a gateway or trunk and Route pattern needs to be created to point to this gateway. The dial-peers and other config needs to be done on 2911 to accept inbound calls and to send the calls out. Depending on type of ports ( FXO/PRI ) and protocol the config will vary

h323 gateway sample config is provided in the following link

Thanks for your input.

I'm actually looking for the remote site configuration. Do you know of any example configuration or documentation  for CUCM  centralized model where remote site connects to host site via VPN? I'm looking to configure router at remote site. Local prefix calls will route to local pots line.
