We have a remote office that has a 3560 configured with VLAN 1 for DATA and VLAN 2 for VOICE, a router connected to a leased line and a media gateway connected to ISDN.
Our IP phones are set to VLAN 2 and route internal calls through the router and external calls through the media gateway, randomly they will drop the incoming data for both internal and external calls (ie: Users in the remote office cannot hear anything but external or HQ internal users can). Also control signals to the phones dont make it through from HQ.
I am not sure if this is an Avaya phone issue or Cisco switch issue but as all the phones suffer at the same time it would appear switch related, it seems like the switch holds up or drops traffic from VLAN1 to VLAN2 but only occastionaly.
Does anyone have an idea what might cause this?
Thanks,
Simon.
