I have a question regarding DNIS Name in SIP Trunk. I have setup SIP Trunk as you can see in the picture. But when I try to contact the 1234567 number from PSTN or Mobile Number, the DNIS Name doesn't show up. The receptionist phone will display my PSTN or Mobile number, and doesn't show the DNIS Name "ABCD Company". Should I also enable Distinctive Caller Id in General setup? or is there any setup that i missed?
