Hello,
I'm having an issue getting a VoIP phone to work on an old 2950g (IOS 12.1(6)) switch. I have configured the VLAN and the phone is able to get an IP address in the correct subnet. However, the phone doesn't register. When I plug the phone into another switch, the phone registers. Any help is appreciated.
Here's the config from the switch (Vlan269 is the voice vlan):
Current configuration : 2369 bytes
