hi, i'll give a quick run down of kit:
Panasonic KXNT-321 VOIP phone
HP procurve switches (various)
We currently have 2 VLANs set up. STD traffic and VOIP traffic. The TDE and the phone are both sat on the VOIP VLAN.
VLAN has a static IP which is defined on the TDE and the phone. The phone has a static IP and the subnets are both the same. Both are untagged in the VLAN. The phone is registered on the TDE and can communicate with it. The issue is voice doesn't return from the phone to another user. They can hear the user but can't talk back.
I have tested the phone on the same switch the TDE is plugged in to see if we have a rogue config on a switch and it still doesn't work.
Any help would be appreciated.
