Hi All.
I've got a waplte router with 15 voip phones behind it.
RSRP:-80
RSRQ:-10
SINR:16

When I ping from router to voice provider I get 14min 25avg 35max with no packet loss what so ever.

SIP helper is disabled as per all my other sites.

Problem is, the voice quality is insanely bad, and when logging into providers hosted pbx, its show phones latency up to 300-500...

Provider says I have a bad internet connection.

Connected router to Librenms and everything looks 100%.

Any advise/questions for more info will be appreciated.

Thank you!
