I have a 7935 on a remote subnet that will not register. Network is as follows CCM3.3 -> 3660 -> t1 -> 2621 -> 3524XL Port config on 3524 is:
switchport access vlan 2
I have 20 some odd phones on same subnet that work fine. When I bring the conference phone back to the local sub, it works fine. Any ideas?
What error does it give you? Does another model phone work on that port?
I just figured it out. DHCP server had been moved to a different port, old nic couldn't deal with trunk, had to be set to access mode.
switchport mode access
switchport access vlan x
