I work for a hospital. We have extended our Avaya Definity switch to several private practice doctor's office. This allows the doctor's office to have a single phone they can call directly into any hospital extension.
Does anyone have any experience setting this up on with a CallManager or with Cisco routers. I'm not quite sure where to start.
Hi, yes to both your questions.
To have CM see the line like a "physical phone", you configure the FXS port in SCCP mode, thing for which I can give you the link once you decide to go that direction. You could also use an ATA that has two FXS ports.
In any case it is important that you find out which exact type of line is that, like a "dry pair" or OPX with loop current, etc. This to avoid purchasing the wrong hardware.
Note that in most cases provisioning such a line is more expensive in terms of time and HW, than an IP phone over VPN.
Hope this helps, please rate post if it does!
