I’m looking for a help in designing a voip for a 74 user’s (in 1 lan) with 20 wan points (all the wan use a Panasonic PBX )I don’t know if I can use the express call manager for that in case i need a billing system ….
Dose anybody have a similar case ?? only the callmanager will help this case ??
What kine of termination could I use for the wan PBX??
Is the 3725 enough for me?
if someone have the same scheme and can share it will be great
