NS700/NS1000 How to make SIP work over Starlink

[bs_stkr02]

Hi all,

Not sure if it's possible, but has anyone had any luck getting these systems to work with SIP over a Starlink internet connection?

I've tried STUN (maybe not correctly however) and I've tried UDP Keep-Alive packets to no avail. Would love some recommendations.

If it's not possible to do this directly, what can I do to make it work besides having an SD-WAN service with a Static IP?

I believe basic Starlink utilizes CGNAT for it's inbound connections similar to some of the other ground based wireless carriers like T-Mobile and SIP will just not work correctly.
Going the static route and having an external public IP and utilizing port forwarding might be the only option.

Isn't this exactly the use-case for STUN though? To punch holes in the NAT to keep those connections alive?

I'm probably expecting too much from these systems in this day and age...

No STUN won't work on CGNAT, you need to think of something else for this one....I have got some hosted user licenses on a VoIP platform and used them on ATA's and plugged into an analogue line card....not a great solution but one that works.

Your other option is VPN into a site not using CGNAT and sending your voice packets along VPN to PBX.

Ah bugger, had a feeling that would be the case.

Too easy, I'll have to look into something a bit more suitable.
