Sipura SPA-3000 PSTN Outgoing - Asterisk problem

I've had my SPA-3000 successfully working for both incoming and outgoing
calls to/from the PSTN but outgoing calls have stopped working!!

I'm using [email protected] and I don't think I've changed anything...

Here's the debug output of the Sipura (on 10.0.0.252) when I place a
call from an Asterisk extension:

and here's the section from sip_addition.conf

I've defined Voip User 1 as 'Asterisk' and entered the correct password
on the SPA-3000. Screenshot at:

Any help most welcome!

Thanks,

Hmm, looks a bit dubious specifying host= twice.

Drop into an asterisk console with 'asterisk -Rc', type
'sip debug peer sipura' and see if that gets you anywhere.

 

Thanks Alex, I've tidied that bit up (removed the host=dynamic)
Asterisk debug messages mirror the Sipura logs btw

I've just tried adding username=Asterisk to [sipura] and it has started
working again. I don't recall removing this so I've no idea why it
stopped working.

I now need to read up on the difference between 'fromuser' and 'username'!!

It stopped working because hosts specified with an IP address [eg
host=10.0.0.252] must have username= specified. This would hopefully appear
in error logs somewhere.

I believe one is the username you use to authenticate with Asterisk with,
and the other is the username component of your SIP URI, eg
sip:. So you would specify both if you wanted them to
be different.

Also, it's handy to use the 'username' to contact a peer before it's
registered with Asterisk, which would happen if your server rebooted in the
middle of an expiry.
