T1 to VOIP on a 3825 - newbie

I am unable to get a call to come inbound from a T1 on a 3825, and rout it outbound via 711 to an IP address. Please see my config.

the call coming in should have a dnis of 3599

If I do a debug voice dialpeer inout and initiate a call I can see the call come in but this is what I see:

Result=NO_MATCH(-1) After All Match Rules Attempt

can someone shove me in the right direction? Thanks.

looks like you need an INCOMING dial peer to match. Try this:

dial-peer voice 1 pots

incoming called-number .

This worked. Thanks for the help. If you have time to explain why this worked I'd appreciate it.

Re: T1 to VOIP on a 3825 - newbie

A great book for you is the Cisco Press - Cisco Voice Gateways and Gatekeepers. I highly recommend it. Basically in the gateway you have to have both an incoming dial-peer and an outgoing dial-peer that match the Protocol, codec, dtmf, patterns, etc that you are using. The incoming dial-peer accepts the call into the gateway, the outbound Dial-peer directs the call to a destination. There is a lot to cover here, but incoming and outgoing do not have to be the same protocol, dtmf, etc, and this is known as a SBC if its IP to IP. If its Pots to IP, its just a simple voice gateway. The one thing to remember (and what I should have started with) is that there is a hidden dial-peer 0 on every voice router that can serve as your incoming dial-peer sometimes, but in the case of T1s/PRI's it won't answer correctly, so its best to create your own and set it up to answer all incoming calls ( . means all matches). Good luck with it and welcome to IP telephony.

Exactly what I was looking for. Thanks for the info. All the telephony books I have picked up revolve around call manager. unfortunately we went with a competitor, so not much of it applies. Ill be picking that book up shortly.

Thanks again.
