I am using a 3825 router connecting to 2 sip trunks over WIC1DSU cards for incoming calls. If I wanted to add a third internet T1 for outgoing calls, and a have my connnectivity over ge0/0 port instead of adding another WIC1DSU, what are my limitations? We are using G729 codec, our provider supports 45 concurrent calls.

Thanks!

I have this problem too.

Hi,

It would be always better to have WAN links terminated in the "natural form", that is a serial circuit rather than a LAN interface. This is because you're able to control the point of congestion and apply QoS more effectively.

Beside that, if you have no QoS concerns, there are no issues in doing that.
