I have 2 Quadros that I want to join using a 2-way SIP Tunnel.
I can't get them to register with pending event -

Quadro 1 - SIP TUNNELSLAVE / Could not register with user SIPTunnel_PLN02 on server Reason: User not found

Quadro 2 - IP phone user SIPTunnel_PLN02 [109.176.71.200:5060]: registration failed. Reason: No Such Line Configured

Which indicates I have to setup a user/line on each Quadro. Is this correct only I can't find anything about this in the manual.

In anticipation thanks for your assistance.
