Resurrecting this conversation, as I’m in the same boat.
Vodafone fiber broadband, HT801.
I’ve got the UDP ports open for SIP and RTP (5060 & 5004) on my router
I’ve turned off anything VoiP related on the server (SIP ALG etc)
I’ve got NAT Traversal set up to use a public STUN server (stun2.l.google.com:19302)
Looking at the status page on the ATA, It tells me that I’ve got full cone NAT (Stun)
I’ve entered my SIP details I got from Vodafone. These consist of
A username in the form voiXXXXXXXXX
A mixed case alphanumeric password
A value called ‘SIP’ which is the same as the username
A registration server - resvoip.vodafone.co.uk
A primary SIP server - xx.xx…bbvoice.vodafone.co.uk
I’ve entered these details where I believe they should be in the FXS Port tab. But just like dzuser, my port status remains unregistered. However - something is working, as I started getting phantom calls from sip vicious (dead air on 100, 1001 etc). So much so that I’ve been in and disabled / enabled the settings mentioned here:
And that’s stopped them from ringing the phone every 30 seconds.
Any further pointers and help would be appreciated. It seems I’m close to getting it working, but no idea what the little extra is I need…
