SV8100 Constant Beeping In Receiver

[Wendelspanswick]

Just had a fault come in, when the user picks up the handset on her analogue phone there is a constant beeping in the receiver, this is audible to her and the person she is speaking to. This is a single beep every half second or so. Not one that I have come across before. Phone behaves normally apart from this.
Any pointers?

Have you tried turning it off then on again!

Possibly a message notification. VM? Station to station? Try dialing some cancel codes.

Resolved it. The problem was the adjacent phone on the SV8100 analogue station module was off hook and the alarm was bleeding through to the problem phone. Re-terminating the RJ45 plug from the station port on the SV8100 cured the problem.
