Hi,

Thanks for your reply.

 Doing it the way you've suggested would mean

 Indeed. I already tried that, using the replace() / replace_all() 
textops functions, but I could not even manage to have the header 
modified. It just did nothing at all ....

Besides, in the recent thread Re: [Serusers] HF replace, someone said 
that modifying From: and To "is not allowed".

But I am wondering ... ain't it the "Contact:" header which is used by 
register.so/usrloc.so ?

 fields, then doing a save. This should in theory all
the UAC to register on
the two addresses, it could get a little messy.

 I agree. I anticipate a few issues on that side.

 An alternative would be to create an alias, this would
be fine if you knew
before hand what format they would register with.

 Well, I know which server will send what format, and I can afford to 
hardcode the IPs in the ser.cfg. But after reading the section about 
aliases in the ser Admin's manual, I must confess it is not clear for 
me. Could you elaborate on that idea ?

Subject: [Serusers] I need to alter and duplicate REGISTER saves

Hello everyone,

After looking everywhere in the docs and ML archives, I couldn't find a
way to solve my problem, so I would appreciate any help.

We have several iPBX servers sending REGISTERs to a SER registrar. Some
of those servers send us the numbers to register as aor in the form
0XXXXXXXXX (local numbering plan), some other in the form 33XXXXXXXXX
(local country code prefix). For various reasons, we need to handle
those different REGISTERs simultaneously, and be able to lookup both
formats in the location database.

What I'm looking for is a way to "duplicate" the REGISTER entries, i.e.
when ser receives a REGISTER for 33XXXXXXXXX, I'd like it to save() the
33XXXXXXXXX, but also create an entry for the corresponding 0XXXXXXXXX.

Example : SER receives a REGISTER request for 33122334455. I'd like to
have two aors in the location database, so that lookup("33122334455")
and lookup("0123344556") would both return the same thing.

What I have in mind is something like this :

if (method=="REGISTER") {
    # Always save the original aor
    save("location");

   # If the number starts with 33, also save a duplicate aor in the
0XXXXXXXXX format
    if (search("^From.*sip:33.*")) {

       # Insert some code to alter the received SIP message and change the
       # number in order to save the 0XXXXXXXXX aor
       # ...
       # ...
       # ...

        save("location");
        break;
    }
    break;
};

Can anyone help ?

Best Regards,
Jerome Martin
