Random Audio when Transfer to Queue

[anco]

We have a server on V20 update 4 that has an issue with internal flow transferring playing random audio before the actual MOH from the queue.

Number XYZ > Digital Receptionist A (for choices to 4 different queues) > Choose 1 > Queue 1 > random audio for 1 seconde > MOH from queue

Tried multiple ways to detect where the issue is but I couldn't find it:

Removed the General MOH file > doesn't change behaviour
Removed the MOH from the queue > random audio is played, then silence, so no MOH from the queue as expected

Issue also appears when choosing 2,3 or 4 and going to the queue 2,3 and 4

I've also restarted the server but that didn't help.

Anybody any ideas and a solution for this issue?

My guess, in spite of removing the general MOH, that is what is playing briefly while 3CX sets up the queue MOH. Were you able to confirm that there is no MOH running at all through the entire system before performing your test? I have seen them before over the years where it takes time on some phone systems to place the call so a brief MOH is heard until the call transfer is completed.

Thanks for your answer, but I removed the default MOH file in the system, that doesn't change behaviour, also changed the default MOH to a different file, but still same behaviour unfortunatly.

My question was whether you verified that removing the MOH actually was successful. Maybe reboot the server after removing the MOH? The audio has to be coming from somewhere and the most likely source is MOH.

What is the spec of the machine? I've had it play MOH during transfer due to not enough resources.

Me too. Insufficient resources.

Rebuild the setup in another 3CX with the same specs, same issue, only on normal volume instead of very loud. It seems that 3CX is playing system MOH when transferring from Digital Receptionist to queue.

When we disable system MOH issue solved is second system.

Unfortunatly not in innitial system, reboot system / Optimize Database doesn't work. Probably some other issue and strange thing here is that the second of MOH is very loud when going from Digital Receptionist to queue.
