Unanswered calls ring phone and then leave empty voicemail

[rick]

I have a Mivoice 250 with analog trunks.
When a user makes a trunk call and the call is unanswered at the other end, the phone that made the call rings when the handset is put down. Then the voicemail/message lamp lightson that phone but there is no message in the mailbox.
Anyone ever come across something like this and how do I stop it happening?
Thanks in advance!

rick,

It sounds as though you are not giving a positive disconnect from the POTS line and it thinks the call is still ongoing.

I would try to perform the Loop Loss and Hybrid Balance tests on all of your POTS lines and see if that fixes the problem; do each test 3 times.

If it continues I would have a Buttset on each line to see which POTS lines are having the problem and then put a positive disconnect device on those.

Thanks,

TE

Thanks for that.
I will do the tests as you mention and see what happens!
