Is there any documentation on the NAT side for this gateway. I have gotten it to register but it rings once and then voicemail… The Server is in a datacenter and the Vega 50 at a remote location.
PS – Using PJSIP and latest FreePBX and Asterisk 13.13.1
There was quite a bit of discussion about setting up Vega 50s here a couple of months ago. It seems to me one of the things that wasn’t working was the PJ-SIP Channel Driver. Try switching it to Chan-SIP and see if the problem is the same.
