Hi Anca,
I figured out the solution that you were referring to. I added the local_route
section and changed the header in there, and it works.
The only problem now is that the AVP variable I set in route doesn't seem to be
persistent into the new request inside local_route. This is a problem because I
need some way to send the variables to local_route so that I can put them into
the new request. Is there a way to make an AVP variable persistent into the
local_route as well? Or maybe there is a better way to make these variables
accessible from inside local_route?
Here is my working code (with statically set caller id. I need to make this
dynamic):
local_route {
if (is_method("INVITE")) {
remove_hf("From");
append_hf("From: \"TEST3\" <sip:[email protected]>;tag=$ft\r\n");
#exit;
}
if (is_method("BYE") ) {
acc_log_request("internally generated BYE");
}
}

Hi Brett,
The b2bua generates a new request with the info from the received one. The
problem is with the changes upon a request not being visible to the following
functions called from the script.
So you have to change the header on the generated one, in local route.
Regards,
Anca

In addition, the uac_replace_from(display,uri); function does not seem to work
either. I tested this function by putting:
uac_replace_from("TEST", "sip:[email protected]" );
immediately above the call to B2B_INIT_REQUEST and the outbound "From:" header
remains unchanged (incorrect).

Subject: [OpenSIPS-Users] B2BUA "From" Header & Caller-ID Question
Hello,
I have a working implementation of the B2BUA modules for OpenSIPS. One problem
I am having is that the B2BUA module doesn't seem to respect the "From:" header
that I updated before B2B_INIT was called (at the end of the script). Before I
call B2B_INIT, my script looks up the correct caller-id from a database and
replaces the "From:" header with the new information. Here is that code:
xlog("This is an external call...");
avp_db_query("select id from subscriber where username=\"$fU\" AND
domain=\"1.2.3.4\"", "$avp(s:subscriber_id)");
if(is_avp_set("$avp(s:subscriber_id)")){
avp_db_query("select external_cid_name,external_cid_uri,external_cid_uri_domain
from cid where subscriber_id=\"$avp(s:subscriber_id)\"",
"$avp(s:external_cid_name);$avp(s:external_cid_uri);$avp(s:external_cid_uri_domain)");
remove_hf("From");
append_hf("From: \"$avp(s:external_cid_name)\"
<sip:$avp(s:external_cid_uri)@$avp(s:external_cid_uri_domain)> ;tag=$ft\r\n");
}
The resulting "From": header is perfect (it includes the new caller-id
information) and works without problems when I don't use the B2BUA module. It
seems as though the B2BUA module (which is called last in the script) does not
respect the new header, and instead processes the call using whatever was in
$fu when the script started. Unfortunately $fu is not writable, so I can't
directly change it.
What are some possible work-arounds to get the B2BUA module to create the new
call but include the "From:" header that I've updated earlier in the script?
Any ideas are greatly appreciated!
