Hi,
I tried many things but none seems to work. I am using ser 0.8.4.
With the following code in ser.cfg, every time a REGISTER arrives with
the 33XXXXXX format, the request is logged in my duplicates log, but the
subst line does not seem to work. I tried replace and replace_all also,
but no luck.
I though that maybe the exported shell variables I am dumping in my log
file are not updated after the subst, but a serctl ul show clearly
display only the 33XXXXXX numbers in the location database.
Here is the code I am using :
if (method=="REGISTER") {
save("location");
exec_msg("echo -e REGISTER `date` '\n' `printenv
| grep SIP` '\n' >> /var/log/ser-register.log");
if (search("^From.*sip:33.*")) {
subst('/sip\:33/sip\:0/g');
save_noreply("location");
exec_msg("echo -e REGISTER DUP `date`
'\n' `printenv | grep SIP` '\n' >>
/var/log/ser-register-dup.log");
break;
}
break;
};
Any idea ?

In your example you want lookup("33122334455") to return the same as
lookup("0122334455"). Well if 33122334455 is an alias for 0122334455 it
will. First it does an alias lookup of 33122334455(a)mydomain.com which
replaces the r-uri with 0122334455(a)mydomain.com then it does a lookup on
that, finds a match and does a further replace with 0122334455(a)1.2.3.4 (The
IP address of the UAC from the Contact record)

Hi,
Thanks for your reply.

I've had the situation where I've needed to update the Refer-To: header as
the gateway was unable to handle it in a satisfactory manor. For this I used
the subst function in the textops module, I'm not sure if this functions any
differently to the replace functions.
Doing it the way you've suggested would mean
modifying the From and To
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".
It's recomended not too, though most people want to modify the From on
INVITE's. It may not be such a problem on a REGISTER method, just do a
save_noreply("location")
But I am wondering ... ain't it the
"Contact:" header which is used by
register.so/usrloc.so ?
It's Contact header is used as the location of the UAC,
'username@ipaddress_of_uac'. The From/To fields are used as the username
part on the sip registrar, generally the From/To are the same though may not
always be the case.
See http://www.faqs.org/rfcs/rfc3261.html section 10.2
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 ?

};
Can anyone help ?
