Hello All,
I got a problem with Mitel 470 on SIP trunk, there is one way voice behaviour. Voice is going out from Mitel, but mitel do not receive external calls voice. There is an SBC connected into Mitel, and going via SBC to Provider Box. We can see traffic on traces, invite, ringing, etc. But voice is just going out of the Mitel PBX, no coming voice into it.
Any idea?
kind regards
Wojtek,
