You'll have to permit traffic from that voice vlan on the port 2000. Port 2000 is used for IP phones to talk to Call Manager server. If this port is blocked , the phones will lose registration to CM server.
yes,i agree...but why are there packets dropped on port 2000 on the gateway...maybe something stupid but could it be that when the 7920 is placing an external call that the CCM is setting up the call with the gateway (SCCP) and then at gateway level the protocol is dropped because the other side does not know SCCP?
