Hi! I am trying to get 3CX up and running with the few Avaya 1140e SIP phones. 3CX recognize the 1140E's and i am able to set and extension on each sets.I also got the 3CX phone working as well as my iphone with the 3CX app. Now my problem is the 3CX can call the 1140e's i can pick up and talk but when i use the 1140e's to dial out to the 3CX phone on the computer it says (call denied,prohibited). My 1140e's can receive calls but they cant dial. I hope someone can help me out. Thank you!
