After 220.127.116.11 we have been experiencing GS Wave App No Audio on Mobile/4G
There have been several post around this ISSUE, however so fix or resolution…
Grandstream Engineers please review this issue.
I have downloaded an older version 18.104.22.168 tested on my Freeswithch PBX and it works perfectly on Mobile Data/4G and Wifi
The lastest version 22.214.171.124 Only works on Wifi not on Mobile Data/4G
There problem is mobile carriers use IPV4 and IPV6 on devices.
Release 126.96.36.199 when register to PBX show IPV4 from the Mobile Device
Release 188.8.131.52 when register to PBX shows IPV6 from the Mobile Device
