Hello all,

I'm a 911 center systems engineer and fairly new to Cisco products, and I was tossed a new project. We run Cisco CallManager in our mobile center, and we found an issue with the time that CallManager takes to "pick up" a ringing line.

The basics are we have POTS replacement devices going into FXO ports in the router. The first two incoming lines work fine. The third used to be connected to a fax machine as well as CallManager (mostly used for outgoing calls), but the fax has gone away. My working theory is when the system was originally set up, they wanted to give the fax machine time to pick up the call before CallManager grabbed it and presented it to the user. I'm not looking for a "do this to fix it", I'm just looking for what the timer might be called so I know what I'm looking for in the documentation.

I don't know what other information might be be needed to help me out, so let me know what else you need to know and I'll get it.

Thank you!
