Relates to: Yeastar S50
Firmware Version: 22.214.171.124
After upgrade to 126.96.36.199 I noticed a very poor voice quality on conference.
The voice is distorted, broken and choppy.
The problem appears only when we are using conference, after selecting the conference number and entering the PIN code.
Other SIP trunks works good. Sound is perfect.
No problem with Internet Connection
No problem with router
Settings checked with our provider
Firewall rules checked
Any ideas ?
