3Com NBX-100 Multicast Between Sites
Posted on 2004-11-09
We have been running a 3Com NBX-100 system for some time now with the following configuration:
*E1/T1 PRI Card for trunks
*IP On The Fly
Recently we brought a remote office (located acrossed the street) online with the main office via a PTP T1, not bridged.
Office 1 <<--Cisco 3600, 192.168.1.0-->> (PTP T1) <<--Cisco 2600,192.168.2.0-->>
So two separate net's exist, the NCP resides on the 192.168.1.0 network. We have managed to bring phones online at both sites, dialing out works, transfer of calls works, music on hold works. We run into a problem when attempting to conference calls, as well as with time/date synchronization at the handsets.
it appears that this is due to a multicast issue. My basic question would be what is the proper configuration for multicasting between these two sites, using the routers and connection we currently have? Bridging the two networks really isn't an option so we are hoping to be able to pass the MC packets through the T1 ckt.
Let me know if I can offer further information.
