Hearing own MOH

[Alphabetic]

Hi all

i know this has been discussed before but im unable to come to a resolution.

I've got 2 3CX systems on the same SIP Provider (Unsupported) both have sip reinvites enabled.

When I call A to B and B puts A on hold, A can hear their own MOH.

Can I prevent this?

Im not fluent in traces so not entirely sure what I need to be looking for.

I can see that A sent an invite with attribute sendvonly and B replied wit recvonly..

Ok I recreated PBX A SIP trunk to the generic SIP template which disabled reinvites and this problem has gone away.

Am I going to lose the functionality of seeing caller ID when we're attended tranferred calls?
