Call Manager 4.2 and Cisco 2811 router Configuration

[mt6322]

We are adding a remote site using a Cisco 2811 with SRST for 15 users to our existing Cisco Call Manager 4.2 at our main HQ. The two locations will be connected via point to point T1. Also, the remote site will have its own PRI ISDN for DID numbers and for local and long distance calling. We have already ordered the Cisco 2811 router with the 2 T1 interface cards and the SRST software and I was assigned to handle this project. I am seeking assistance in configuring the Call Manager and the Cisco router. Any sample configuration and documentation will be greatly appreciated. Thank you in advance for your help.

Thank you for your response.

I guess the sample configuration if for the Cisco 2811 router for the remote site.

How do you create the calling search space and route patterns for local and long distance calls at the remote site ?

We want to setup the Cisco IP phone at the remote site to dial a 4 digit extension when calling the main site through the point to point T1 between sites but all local and long distance calls from the remote site must leave via the local PRI circuit. How do you create the calling search space and the route pattern to allow such calls ? Is this done on the Cisco 2811 router at the remote site or through Call Manager at the main site ? Please advise.

Thanks again for your help.

The CSS and RP's are all done in CallManager. The remote router will use the Dial-peer configs if it loses contact with CallManager.

Thanks again for your prompt response.

I found the Cisco Unified SRST docs and I hope this will guide me through with my setup. I am gathering all the info I need to get ready in setting my call manager and the router. Any additional info will be greatly appreciated. Thank you.

how are you looking? is it up and working?

 

[mt6322]

We just received our srst enabled router and we are in the process of configuring our remote site.

Will let you know how it goes.
