[Freeswitch-users] Working with an ancient SPA-3000 in the UK, can't get gateway registration working?

[Matthew Macdonald-Wallace]

Hi all,

In an attempt to add VoIP to my home network, I'm working with
Freeswitch and FusionPBX.

My outbound connection to the PSTN is via an aging SPA-3000, and whilst
I can get the SPA-3000 to register correctly as a "user", I can't get
the "gateway" side of things in FusionPBX/Freeswitch to register with
the SPA-3000 for outgoing calls.

All of the articles I can find online relate to the SPA-3201 or similar,
which is a very different beast to the SPA-3000.

The error in the logs is as follows:

2021-02-20 08:53:57.680948 [NOTICE] sofia_reg.c:454 Registering

86e4-11a25d3c9d00 Failed Registration [503], setting retry to 30

and my settings look like this:

I'm sure this is something really obvious that I'm missing in the
settings, so all help is appreciated!

Thanks in advance,

Matt
