Call Queue with no audio - 3CX V20

[leocalabretta]

Hi everyone,

I updated 3CX on Premise Linux from V18 to V20. I have an unsupported SIP provider that worked perfectly with V18. Since updating to V20, calls transferred to an extension via the Queue have no audio. The only way to fix this is to put the call on hold again and then resume it. Can you help me?

Thanks everybody
