Hi,
Looking for some assistance with our Mitel 3300 MCD.
We recently moved to a new ISP and were provided with a new Draytek 2830.
Everything is now up and running except for our Teleworker phones at remote sites. When I say not working that is not strictly accurate. You can phone from the teleworker phone, the user (internally or externally) can hear you but you cannot hear them. I've read articles on one way audio but they tend to be SIP issues.
I've been trying to get responses from Draytek as BT (Provider of the Mitel) say everything is working.
I'm a bit of a novice with routers but from what I've read it looks like firewall ports not being opened - I'm fairly sure they are.
All advice welcome.
Thanks
