I am extending a subnet over T1 bridge using Adtran 3205 routers. The host site is connected via Cisco 2801 router with a switch card to th e HQ site. The remote site is connected to the host site by the bridged Adtran's. The switch at the remote site is a Cisco C2960.
I connected a PC to the ethernet port on the remote side and it worked. I put in the switch and it put down the port. I disabled Spanning tree and the port came up, however still no connectivity thru the switch. I changed out the switch for a dell powerconnect 2624 and then PC connectivity was established, however, my Cisco IP phones will not register. Data is VLAN1, voice is VLAN 10. The Adtran routers are set to trunking mode, as is the switch port on the host site router.
I am stuck, the bridged routers should pass all traffic regardless of protocol (802.3q) and documentation for the dell switch says that is will ignore the priority packets and just pass them along untouched. Any suggestions. This site is supposed to come online Monday, tomorrow and I can't get the phones to work!
