Thank you, there was another value in the Explicitly list addresses for inbound traffic box

I am trying to setup a Snom One Mini with a Sangoma Vega 50 using the PSTN. I have a non-registering SIP trunk between the 2 and can make outbound calls and internal calls however when an inbound call is received, it seems to be passed from the Sangoma Vega to the Snom One but returned to the Vega with a 404 error. Does anyone have any experience of configuring these devices? The tech support guy at Sangoma seemed convinced that it was something in the Snom that was causing the issue.
