Hello Dave,
I use the version 2.7.0.0_x64_Beta7E. Since I often fly with different callsigns, I have tested the beta version. It works with Simbrief also very well.
On the last 3 flights I noticed a problem. After the pushback and engine start I get no release for the Taxi Request. There is no answer. Also the automatic change from ground to tower at the runway did not work. I set the tower manually, then the release to start was no problem. The rest of the flight went without problems.
I have saved the log file. I have attached a part of it:

Hi Andreas,

When you requested taxi clearance, P2A understood this: Recognized Speech: AIR SPRING One Niner Six Six Request Taxi to Runway Three Four 20:24:07

Apparently, and as I understand it, P2A takes this as a readback: HandleTaxiClearanceReadback 20:24:07

Did you try to say : Ground, AIR SPRING One Niner Six Six, Request Taxi to Runway Three Four ?

I see that for takeoff clearance, you asked Tower AIR SPRING One Niner Six Six Ready for departure Runway Three Four and it worked, so I guess this may be the reason.

Hope this helps.

And if you actually said "Ground", try to wait a bit more after pressing the PTT and starting to talk.

Beta 7F, and now 7G, do fix some issues with Taxi requests.

Update to 7G and this issue should be resolved, as long as your request is recognized correctly.

Dave

Hello Dave,
I have installed the Beta7G2 version. The cab request works again. Also the automatic switching to the tower frequency works. So everything is ok.

Thanks
Andreas
