Hello people, recently installed axon the free edition in my pc and I have 4 grandstream DP 715/710 DECT phones. I can't seem to be able to configure the phones to dial the extensions, They ring and hangup so if there's a call I need to transfer it I can't via the extension I have to dial the whole number and that makes it ring all the other lines. I tried with a free version of 3cx and the extensions work just fine so it has to be a configuration issue with Axon system. Please let me know what you can make out of this. Thank you!
