Router 2901 as VoIP gateway

[espinedo1]

Hello,

I'm trying to configure a CISCO 2901 Integrated Services Router with a Module VWIC3-1MFT-T1/E1 as a VoIP gateway.

I'd like to know if is it possible, and if there is a especific document in CISCO documentation explaining it.

I have the following escenary:

Inbound calls:

     PSTN (ISDN)  --> CISCO 2901 --> Asterisk (SIP PBX)

Outbound calls

     Asterisk(SIP PBX) --> CISCO 2901 --> PSTN (ISDN)

I have found some documents which explains how to configure a SIP Trunk with registration

http://www.cisco.com/en/US/docs/ios-xml/ios/voice/cube_sipsip/configuration/xe-3s/asr1000/voi-sip-trunk-reg.html

And how to configure the VWIC3 module

http://www.cisco.com/en/US/docs/routers/access/interfaces/software/feature/guide/vd-t1e1_vwic3.html

I'm very new with CISCO and I don't know how to route calls from the module to the Ethernet interface, and if I need to do anything else.

Thanks in advance!

For ISDN you need to configure your T1/E1, plenty of material and also references/examples on CSC, a quick search will provide some basic config

http://www.cisco.com/en/US/partner/docs/voice_ip_comm/cucme/admin/configuration/guide/cmebasic.html

Search pri-group timeslots to get more examples.

Then you'll need to configure dial-peers for in/out calls, search cisco.com for dial-peer configuration and you'll get all the info you need on how to configure them.
