Music on hold issue

[Praetorium]

Hi Guys

Not sure if this is the right thread, but i've got a very strange issue cropping up every now and again.

When phoning certain clients i get my own music on hold (custom wav file) playing when they put me on hold/transfer me. I've only encountered the issue with 3x clients now.

I've tried looking for a setting that could be causing it, have ended up empty handed. Version 18.0.214

Regards

Pieter

Hi @Praetorium,

On your SIP Trunk, disable Supports Re-Invite and Support Replaces. Let me know if this happens again afterwards.

I have experienced this too but only with a specific vendor that I call. It doesn't happen every time but often enough to bring me here. On my system, both of those options are already unchecked.

In that case, your Provider most likely is sending a re-INVITE at some point telling your 3CX to "go on hold", in which case your 3CX will put you on hold and play the MoH you have set.

Ultimately this is a provider behavior that we cannot (and must not as per RFC) override.
