We currently have Bogen and Valcom paging amplifiers connected to our Nortel Option 11. We would like to move this paging gear over to a Cisco 2811 Gateway/CUCM 4.1(3). How do I determine what type of VWIC is required in the gateway to support this configuration?
Hahaha!! I wish I was a Cisco madman :)
OK, this final result does tell us what we need to know. That the current setup is actually using a Trunk or FXO style port. This means that the you can use either an FXS or FXO on the Cisco side as long as you order up the TAMB mid-point integration piece (very cheap $$). You should be good to go.
