I'm new to VoIP and would like some advice:
Two of our sites have a dedicated E3 connection between two 3845 routers (IOS Version 12.4(3e)).
The connection is currently used for data only but it is not fully utilized and we would like to use it to send voice traffic between the sites also. The plan is to connect the PBX at each site with an E1 ISDN Primary trunk to the router at the site.
The router will send this voice traffic in IP packets to the other site over the E3 connection.
What card do I need in each of the routers (there is a HWIC and NM slot available in each)?
What are the commands to set up the interface card to packetize the voice traffic on one end and de-packetize it on the other?
A LLQ will be setup for the 2 Mb/s E1 voice traffic on the E3 connection.
