New Office. 2 Wan lines + possibly a 3rd.
Wan 1 is a bonded T1 (3 meg)
One voice trunk coming out of a shared T1 on one of the WAN. 12 channels/12 channels.
Planning to use a VWIC card to drop the T1 in and come back out via DSZ/E1 interface to put into the PRI card on the PBX switch.
With that said, and I am NOT using a Cisco VOIP product but will use put a 16port Ethernet NSM module in the 2811, do I need the PVDM module.
Or will just the base no frills 2811 model suffice ? No special version of IOS , etc to pass the 12 channels of voice out ?
