I cannot get internal paging to work to the phonesets. A user dials the paging extension (611) with no speakerphone output. Any suggestions an where to look for the problem / solution ???
The 3Com 4400 switch or equivalent does not support paging by default you have to disable IGMP Multicast filtering. The web config is the easiest way. I realize I'm assuming you have 3 Com switches but I know alot of people that buy phones an d switches as a bundled pair and have a hard time finding out this tiny bit of info.
In particular, you need to disable IGMP Snoop mode (unless you have a multicast router enabled and need to route NBX multicast to either remote IP phones, or another NBX via VTL's)
4400 command is br mu ig sno dis
1100/3300 is br mu ig dis
