I am in the process of implementing a similar sort of thing except I'm using
RADIUS instead of MySQL for authentication.
I've found that some SIPUA will add the Remote-Party-ID field, and in this
case when you add an additional one the first
will take precedence. We have remote sip domains that use extension numbers,
and when they place calls out to the PSTN
via us we require them to present us with their PSTN number. This is taken
care of via the remote proxy by means of the
RPID attribute in the RADIUS database.
To remove an existing Remote-Party-ID header use the following
if (is_present_hf("Remote-Party-ID")) {
remove_hf("Remote-Party-ID");
};
# Do the auth
append_rpid_hf();
An example RPID value would be
"01234567890" <sip:01234567890@sip.mydomain.com>
Cisco provide some documentation on the matter

Subject: Re: [Serusers] multiple domains and pstn
The rpid doesn't seem to be in the document. Anyway, I
dig into the source file. Here is what I found, rpid
is stored in ser database in mysql server. It is in
the subsriber table and rpid column.
You need modparam("auth_db", "use_rpid", 1), because
the default value is 0 and not using rpid.
Optional modparam("auth_db","rpid_column", "rpid"),
which is default.
There are other params documented in the README file
in modules/auth directory.
rpid is retrieved during proxy authentication.
Function append_rpid_hf() adds the rpid value into the
header field "Remote-Party-ID".
rpid doesn't have to be number only. It can be any
format.
Here is an example, rpid columns has
"test" 8005551212
The header has a header
Remote-Party-ID: "test"
8005551212;party=calling;id-type=subscriber;screen=yes
It should give the caller name as test and id as
8005551212, hopefully. ;) I should have a rpid capable
PSTN gateway next week and let you posted.
Thanks,
Richard

Think I got the answer for question 1. Use rpid
stored
in each subscriber in the database before forwarding
the call to PSTN gateway.

Hi,
I have a few questions about multiple domains and
call
from/to pstn. I don't want to change the ser.cfg
script everytime a new domain is added. How can I
support the following features?
1. Every domain has their own 3 or 4 digit dial
plan.
When they call PSTN, their caller id should be the
either a prefix plus their internal number or a
generic receptionist number, but not the 3/4 digit
internal number. Different domains have different
prefix. Is there a way to do this without changing
the
script for every domain?
2. Should interdomain calls be prohibited? Is it
preferred to send the call to PSTN and hairpin
back?
I
know it consumes more resources but would it
provide
better privacy? If that's the case, how to
prevent
interdomain calls, i.e. how to verify from and to
URI
have the same host parts?
3. When PSTN calls come in, should I use
prefix2domain
in pdt module to convert the PSTN number to a
local
domain number? Any pitfalls?
This list has been great! Thanks for all your
help.
