IP Telephone
I'm wanting to do something I see as simple but not sure how so go easy on me. I have a Cisco 2811 router with a 2 port FXO card installed. The IOS is 12.4(13r) and the image file is advipservicesk9. I have an analog line that I want to ring a Cisco VoIP phone that is configured with the directory number 3910. Any help would be appreciated.

I don't seem to have a PVDM installed so that would explain it. Not being a VoIP guy I wasn't sure if one was needed when using an FXO card. What would be the minimum PVDM needed to run the scenario I need?

Thanks. I appreciate the information. I'm looking at a PVDM-48 which should get me what I need for now and a possible fractional PRI in the future, which will of course make using the fxo port irrelevant. Go figure.
1. Hardware.
Ensure you also have PVDM (DSP) resources, otherwise your FXO will not be usable (see this at the CLI with a show ver).
2. IP Telephony
Configure your basic telephony. Google this - there are bucketloads of minimal configs on the web.
3. Configure dial-peers for external connectivity.
Google this as well. Best to build these to suit the area you are in.
4. Configure voice interfaces - generally want to use PLAR for an FXO.

That should give you a good high-level start.
