X6U v2 Conference Audio Issue when 2nd party hangs up

[grcomm]

I have a X6Uv2 FW:2.12.16.20 running (3cx v18/9 build 20) here is the scenario:

X6Uv2/Caller 1/Caller 2 While connected as a conference call. Tried both via Stun and behind SBC

If caller #1 hangs up the call automatically switches to #2caller and audio is fine.

If caller #2 hangs up the call automatically switches to caller #1 But the audio is lost one way and in order to regain two way audio I found if you place the call on hold then resume solves the issue.

I tested V63 & V65 series and both have the same audio issue as well. Also tested x6uv1 and x4uv1 and both work fine.

Any ideas let me know!

Would be interested in hearing if you have the same issue with V20 (which will also provide you with firmware 2.12.17)
