Have a client on Starlink (older dishy with Ethernet capability). Trying to setup VoIP using a Grandstream GRP2612W with 2Talk & it won't work on the Starlink connection - it will sometimes say registered, and can be seen from the 2Talk portal, but won't make or receive calls.

It works fine on a different internet connection, & the android 2Talk app works fine on the Starlink connection.

Anyone using 2Talk on Starlink who could comment? Wonder if @coffeebaron may have setup this config? Any thoughts appreciated. Thanks!

Hi, is the 2612 set for UDP or TCP for sip transport, change it to TCP and see if that helps. As Starlink is a CG-Nat service you may find their NAT router timing out and cleaning up UDP sessions early, this often causes the issue you described. Cannot say it's the issue but worth a try.

Thanks very much for the response - have tried that with no change unfortunately.

I can give you my Fritz!box config for kiwivoip if that's of any help. (Could be wrong, but I think 2Talk may use the same/similar platform). Its been working reliably for over 6 months on starlink (round dish).

I know someone that was told to use port 50600 for kiwivoip, but I just use the standard port.

I typically run Yealink cordless IP phones for VoIP if over 4G , fixed wireless or Starlink. They seem to be more reliable than an ATA.
