We moved to the new v15 and we were using custom templates. Now the phones are red and say not supported firmware and Yealink (Cusotmer Template) under vendor for extension. I went in and deleted the phone and updated with T42G and entered the mac. Now after a bit - under the extensions tab I have 2 entries for the same extension. One in black saying 3cx is the vendor - IP matches what is on the phone. One entry in red that says Yealink or Yealink (Custom template) not supported firmware. The IP is not correct on the red entry. How do I get rid of the duplicate? There is no delete for the bad extension line.
