Annoying MOH during the call

Asterisk Asterisk Support
1

Hi guys! I have some annoying problem

System based on openpbx, quite a large call center and the problem is that from time to time during a conversation (carried out between the server and the client as part of the queue) you can hear music on hold in the background (MOH) randomly selected from a group of MOH files

PBX consists of several servers (asterisk), some for terminate providers SIP trunk, some for terminate softphone, and the central PBX based on openPBX which makes the connection between sipphone and client (for example cellphone using siptrunk)

The problem occurs for different queues, different agents and different sip providers in randomly time of a day.

What could be the reason that they both hear the MOH even though the communication leg between the softphone and the client is set up and theoretically the MOH channel should be quit?

I will be grateful for hints from experienced engineers, what could I check, where to look?

Asterisk MOH isn’t a channel; it is a state of the outgoing channel.

The only things I can think of is a machine fault causing a misreading of that state, or you really are receiving hold indications.

I would start by looking at the asterisk console of every asterisk server involved during a call when this happens. With that many servers involved, it’s quite possible one is misconfigured.
