Hello, We have a 3CX system running 12.0.37098.738 SP6.1 with Yealink T46 Phones and a SIP Trunk to VOIP unlimited. Everything is working find however when a call is made users hear a Europe Style Call Progress Tone "Beeeeeeeeeeep, Beeeeeeep" When it should be a UK style "beeep, beeep". Where is this tone generated? Its on 3cx or on the Yealink? We have another setup with Yealink T46 Phones and 3cx with voip unlimited and we get a UK ringing tone.
