Hello Experts

Having found my issue with the VLAN setup I am left with one more issue:

I have no inbound audio to the endpoints (Mitel 5330e)

Networks looks like this:

SIP provider - Sonicwall TZ-180 - HP 2910al with 2 VLAN's (10.1.1.0 & 10.1.2.0)
Mitel vMCD - 10.1.1.241 static on VLAN 1
Mitel endpoints - 10.1.2.100-199 via DHCP VLAN 2

Peer to peer audio internally works both ways
Outbound audio on SIP trunks works
Inbound audio on SIP trunks - no worky

Attached is the SonicWall access rules - I can monitor the connections and I see the active call; however only the tx byte increment and the rx bytes stay at 0

So it would appear to be a NAT issue, however I can't seem to find my way around it.

Ideas?
