Callback on analog phones

[Schill13]

I have a Hotel customer that says that a room keeps getting bogus calls in the middle of the night and waking them up. Obviously there is no display on room phones, so is there a feature to call back the last missed call to see where it came from?
Thanks

It might be wise to set up internal CDR. I think the CLS = ICDA. Set up a spare TTY port or reconfigure your existing CDR TTY port to capture the information.

Of set the guest phone to divert to reception (display phone) on no answer to see if it's an internal call.

All the best

If it's working, then leave it alone!.

What is he DN of the extension?

Reason: many years ago, some nimrod set an extn number of 1111 in a hotel system. So what? Well, there was another extension with a cable fault that dialled "1111" and provided phantom calls.

There was an error cade (ERR) being generated at the same time. I do not remember the identifier, but the text read something along the lines of invalid digits dialled, or possibly to many digits.

If it is a small system, try using a butt set and monitor the extensions, you may pick a line fault that way.

Is the extension 1800 by chance? In other words, any extension starting with 1 is going to get a lot of wrong numbers since it is just like dialing an area code.
