More drama, started ringing incessantly with calls from short numbers. Brought it home and it worked perfectly.
Going to disable Direct IP call and enable SIP trust and see if it goes the job. :mad:
My first computer was a Sinclair Z80 with 1Kb memory, my mind boggles at the advances technology has made since then. It will be interesting to see how Artificial Intelligence will be used in all spheres from business, medical and entertainment.
Setup a Yealink W60B and W53H combo at home connected to Zyxel MWEB fibre router which works perfectly.
Installed it at our clubhouse via Huawei B525 LTE router, outgoing calls are fine but won't accept incoming calls.
I have disabled SIP - ALG, also tried in security settings to create Yealink...
