Hi there,
long time reader, first time poster for the Cisco community, and i'll admit my knowledge of voice is very limited, but i have come across a peculiar problem and am hoping for an easy answer.
I've looked across the forums, but can't find too much that is relevant. Any insights appreciated!
THE SETUP:
The setup is relatively simple, 3 analogue phones plugged into three ports on the same 2821 router with a 4-port FXS card.
The idea is to have a simple conference call setup from the outside of a premises to a reception area, for delivery drivers to call in and get access through the entry gate.
THE ISSUE:
When phone A goes off-hook, phone B rings indefinitely, even when phone B goes off-hook it keeps ringing. The ringing will only stop once phone a goes back on hook. Has anyone experienced this before and can point me in the right direction for how the phones need to be setup?
THE DETAILS:
Cisco 2821

(i'm thinking given the simple setup there is no CUCM involved, but please correct me if i'm wrong?)
