We have a call center that makes outgoing sales calls through a Teledirect predictive dialer. Our agents are able to make the calls just fine, but our customers see our calls displayed on their caller ID's as "Unavailable." We have three T1/CAS lines configured for the dialer on one of our 3825 gateways. The lines are configured E&M, with 24 ports each. The gateway itself is configured for MGCP, and is running IOS version 12.4(10). I have configured Call Manager to allow for Caller ID to be displayed on all outbound calls on our gateways, dialer lines included. I configured each of the dialer ports individually with our main call back number, so that should be displayed when the sales calls are made. I checked the gateways themselves to make sure that I wasn't unintentionally dis-allowing caller ID at that level. I also checked the route lists to make sure nothing was being dis-allowed there as well, but those were configured properly as well. We are running Call Manager 4.2(3)es61.
I'm at a bit of a loss as to what's going on. I know that MGCP & T1/CAS can be kind of tricky, but I'm not sure what to check next. I'm certain that the gateway is configured properly, and dial peers are correct since outgoing calls are made and connected. If anyone has any insight about what I can check next, I would greatly appreciate it. Thanks.
