Hey guys,
I'm not a particular big fan of regular expressions.. But need to
use it
now.
If I have a string eg <abcde> fghij
/.*<(.*)>.*/\1/
I can never remember the variants. Sometimes you need to escape
the parens, like:
/.*<\(.*\)>.*/\1/
Sometimes you use $1 instead of \1, like:
/.*<(.*)>.*/$1/
-g
How / what is the regex to extract strings within the bracket
(everything else not needed). I just need to extract stuff from within
the brackets.
Thanks a million !

Sam

The difficulty is that , the gateway only can make use of the FROM
header for outgoing caller id presentation.
It can't make use of the Diversion header , so I got no choice but to
stick with it.
Currently making use of AVPOPS to extract the diversion header inside
INVITE and pushing it to the FROM header via UAC_REPLACE_FROM ()

Sam,
if your GW does accept the diversion header, why don't you use this
mechanism instead of using FROM hdr (which highly difficult to
change).
So, my advice is to first understand how the Diversion stuff works in
SIP and then take a look at diversion module:

Hey guys,
Yes , back to this.
Are there any methods of manipulating the FROM header when in Failure
routes ?

Hey guys,
I've managed a workaround by using the diversion header.
I inserted a diversion header and my PSTN gateway shows the
subscriber
number in the original called party number.
BTW , anyone of you have any experiences with using openser to call
forward (server-side call forward) ?
How do u generate call forwarding via openser ?
Regards,
Sam

Hi Bogdan,
I don't think that's possible.
Can I just manipulate the FROM header inside openser ?

Sam,
is your GW able to use for calling party something else than From
hdr?
maybe RPID or PAI hdrs? or a custom hdr?

Sad thing is , I do the billing via the PSTN gateway.
So I definitely have to make the subscriber show up on the
callingpartynumber.
Any way of manipulating the calling party number ?

Hi Sam
I have similar setup , you need muilt call leg accounting in
order to
do proper billing.

I tried to use UAC_replace_from() but seems like there's an error.
Yes, the call forwarding is causing problem. Now it appears as
though
the initial caller (PSTN) called the final called party (PSTN)
and I
can't bill the subscriber !

Hey Carsten,
Thanks for the info.
The example you've provided shows t_relay , which will generate a
INVITE and relays it back to the UA.
How do I get it to relay to the gateway I wanted ?
I've tried rewritehostport("x.x.x.x:5060") before t_relay but
doesn't
help.
Any clue ?
Regards,
Sam

Hi Sam,
Take a look at the uac_redirect-Module. This does exactly, what
you
want to.
Here are the docs:
http://openser.org/docs/modules/1.1.x/uac_redirect.html
In the routing-logic, you just have to define the following
failure-route:
failure_route[1] {
if (t_check_status("3[0-9][0-9]")) {
get_redirects("*");
t_relay();
exit;
}
}
An of course, in the route to the forwarder a "t_on_failure
("1");".

Hey Guys,
Normally if the SIP-UA is call-forwarded to a different
number , it
will send a 'Move Temporarily' to the proxy , which in turn relay
this
message to the originating gateway.
The problem is , if they call forward to a number which the
originating gateway doesn't know what to do with it , it will
just
kill the call.
Can i hijack 'Move Temporarily' directly in the proxy and sending
this
call to a different gateway rather than relaying it to the
originating
gateway ?
Please let me know if you can't understand me.
Thanks!
