Thank you.
I will try and see if any of the diagnostic functions on the Yealink itself can be of use here.
Any tcpdump and packet capture done on the server won’t help me cause I experience the phone being slow even before any packets are sent.
Usually when pressing a digit you instantly hear a beep and you see the entered digit on the display. With V81 on my T23G phones this is a few seconds delayed, which is quite irritating to the user.
It’s not happening consistently with every digit you enter but the phone’s slower reaction is quite noticeable and definitely not happening on V80 firmware.
Not really, Yealink has done it before.
As several users have been reporting this to me, I wanted to see if others are having the same problem.
