Post by: mohkhalifa on August 19, 2020, 01:09:05 PM
Dear All,
I'm using Mitel 3300 and Integrated with Skype for Business via SIP trunk. the problem I can't hear the RingBack tone from the headset.
Everything is working fine I can call Skype extension and also calling from Skype. the only problem not hearing the ringback tone.
ANY HELP!

You can also try to enable "Ignore SDP Answers in Provisional Responses" or "Suppress Use of SDP Inactive Media Streams"
