I have been happily using Zoiper free on various platforms for a number of years. (thankyou developers).
However, after upgrading my Windows10 desktop from Zoiper version 2.39 to 22.214.171.124, I have often been getting what I call broken/staticky sound for receive audio, on either headset or speakers. Stopping this version and reopening 2.39 fixes the problem totally, so that eliminates a lot of packet loss-type causes. Statistics show Quality = 5 , jitter = 10ms, packet loss = 0%
Running the audio setup checks on 5.5 does not show the problem.
Broadband connection is satellite, using MyNetFone for SIP acct.
I would really like to complete the upgrade, but am currently stuck with using 2.39
Thanks in advance for any advice.
