SP30 calling SP30 through Cisco VPN Concentrator

[sos2715]

NEAX2400 IPX

Our remote users us Cisco VPN client to connect to our network.

When a remote user calls another remote user using their SP30 the call is established but the call drops once answered.

Any suggestions?

With the IPS, (I think the IPX is the same) once the link is established, the phone system drops of and then the far ends (spokes) must be able to communicate on their own.

i.e. main site 10.10.10.0 remote A= 10.10.20.0 remote B= 10.10.30.0. Once the phone call is set up 10.10.20 and 10.10.30 must be able to communicate to eachother directly.

NEC may have a new solution but last I worked on this, I set up an access list at the hub site forcing the communication back to the hub router even though the pbx dropped off. As a result, 10.10.20 was routed to 10.10.10 and then to 10.10.30. Not too efficient.

Another solution may be by looping some analog extensions into trunk lines. Then you dial the trunk and get local dialtone and dial an extension forcing the pbx not to drop off as it sees the call as an external call.

I wonder if anyone has a better solution.... I would love to hear.
