Title: Mitel 3300 MXE intermittent busy tone
Post by: bajlu on December 12, 2018, 10:24:51 PM
Good Evening,

I am getting an intermittent busy tone when dialing internally ext to ext. I have analog phones but dialing via SIP on the Mitel. The physical phones in each room are connecting to an ONU. The ONU is configured for RFC2833 Out of Band.
Any suggestions or tips on where to start troubleshooting? External calls in are working fine.

Thanks
