Force a call to use a specific channel

[bgibson]

Does anyone know how I can force a voice call to go through a specific channel on a T1 running CAS and E&M?

I could rebuild the ds0-group to only have that channel but I would rather not do that. Any other ideas?

You can achieve this by using trunk groups. Refer to this URL for more details.

The trunk group is used to group interfaces. Not split them up. If you have T1 CAS you have to build separate DS0 groups to create separate voice-ports. This will allow you to route to specific channels.
