Hello,
We were testing out Linphone for Android using SIP back to our Mitel PBX.
We are only hearing audio in 1 direction (Linphone can hear the audio from the called number, but the person on that end cannot hear audio from Linphone).
A Mitel tech suggested a gateway IP address needs to be entered somewhere in the config but we did not see a place for a gateway IP address.
Any thoughts?
