Bug with mute

[Yealink Support]

Thanks for your files Craigreilly.
But i see there's only BYE message in your PCAP trace, but not the whole call information including DTMF operation.
Could you provide the trace with the whole process for us again?

And today, i tried with our conference system, after i enter the conference ID and pin and talk with other attendees, the hardkey Mute button works well. When i press it, others can't hear my voice, then i press it again, the voice recover.
So is it possible to provide some test accounts for us testing at our side?

Anyway, here i will submit this to our R&D to check together.
Thanks.
