[asterisk-users] SIP header challenge

[Mr. Jones]

Hi Rich,

I'm using a wholesale voip origination provider - they don't deal with
end users. As such they have statically defined my Asterisk box on
their end - there's no registration or authentication by my system
with theirs - other than them hardcoding the destination IP of my
server in their system.

As such I don't have a username to "register" with them. Additionally
they will be originating 100s of DIDs for me at the end of the day, so
it would be horrible to have to register all these in some way.

Also, I don't have any "register" statements with provider A, and
somehow that seems to work out just fine as well.

It seems to me like Asterisk doesn't like the format of what's coming
from their system. Perhaps the addition of: ";user=phone" is confusing
Asterisk?

That's the only obvious difference, that and the Contact: header being
set to "s".

Any other ideas?

TIA
