you can use lcr module to add the prefix.
I'm trying it with some SIP providers and I see:
INVITE sip:0034666555444@sip_provider_domain
and I get in the "183" and "200" a Contact like:
Contact: <sip:aa+ibc@IP:5090>
So I assume that "aa" is the privileged prefix.

this is registrar solution. you use parmissions module and don;t accept

Yes, but without gateway collaboration you get nothing. Proxy must avoid
REGISTER with gateway IP in Contact but in case of a "Contact: domain_to_gw"
the only solution is gw avoiding not IP ruri domain. Proxy can do nothing in
that case.
1) buy
pstn gws that accept no hostnames (just its own ip address) in
the hostpart of r-uri. example, cisco ios with later software
releases.
So really isn't there solution just in OpenSer-Registrar side?? 2) forget the hostpart check all together and instead
check the
userpart, where you have put something special that the gw then
removes.
So you mean for example:
register.deny:
--------------------
ALL : "^sip:.*secret_word_.*@"
----------------------
And later, in any call to PSTN OpenSer should add:
$ru = "secret_word_" + $ru; so the uri
arriving to the gw becomes:
sip:secret_word_01666555444@gw_ip_or_hostname
And the gw should just allow calls from OpenSer with urri username
beginning with "secret_word_" and it should strip it.
that is correct, but the prefix does not need to be secret, just
something that doesn't normally appear in userparts.
Is this what you mean? anyway, a little complex,
isn't it? XDD
why do you think it is complex? one row in register.deny and one strip
at the gateway.
