I have this scenario I have Yeastar S300 and TG1600 GSM
What I want is in port 1 TG1600 where a sim card was inserted when an incoming call arrived it will be directed to extension local 101.
But the thing is I have also configured in Yeastar S300 incoming calls will be directed to IVR except for the incoming call of port 1 in TG1600 which will also be forwarded later on to IVR.
How to configure this? please someone shine a light on me.
