I am using Mitel Mivoice 400 version 4.1 firmware 8740d1,using 2 FXO4 card and one 8DSI card.
Having Analog Hot line and Same configured each hot line on Key of Mitel Mivoice 5370 digital phone.
Problem is when we press hotline key,call gets connected but one speech i can here other party but they cant hear us.
But when we received call on any hotline its working fine.
We check hotline by removing from system and connected analog phone,its working fine.
Also we having one Normal trunk line,its working fine incoming and outgoing.
