Hi Igor
On which route do you send those variables?
Trying to shorten a bit.
Example, call is being sent to a customer device and is getting busy,
this is sent to an asterisk to play the 'busy' tone. But this
is also done with all other kinds of announcements.
if t_check_status("(486)|(600)") {
# BUSY
$avp(announcecode) = "BUSY";
route(DISPATCHMEDIA);
exit;
}
DISPMEDIA contains the ID of a dispatcher group consisting of
two sip URI towards our two asterisk media server.
Extra Header are the used by asterisk to play the desired
announcement in the desired language.
route[DISPATCHMEDIA]
$avp(dispgroup) = DISPMEDIA;
append_hf("IMP-annc: $avp(announcecode)\r\n");
append_hf("IMP-mandate: $avp(mandate)\r\n");
append_hf("IMP-language: $avp(callerlang)\r\n");
if (ds_select_dst("$avp(dispgroup)", "6")) {
# we have a list of servers and a selection in $du
if ($avp(debug) > 0) {
xlog("L_INFO", " --> DISPMEDIA targeting
request to $ru to location $du \n");
}
# Trigger failure route
t_on_failure("DISPATCH_MEDIA_FAILURE");
t_on_reply("DISPMEDIA_MANAGE_REPLY");
route(RELAY);
exit;
}
route(ANNOUNCEREPLY);
exit;
}
See part below commented by XXXX where I already 'fixed' it by adding the header
again and I also had to set $rU again as this was reset to $rU of orininal incomming
call containing a ported number routing prefix, which we strip as one of the first
things to get the e164 number.
failure_route[DISPATCH_MEDIA_FAILURE]
{
if (t_is_canceled()) {
exit;
}
if (t_check_status("(500)|(503)") or (t_branch_timeout() and
!t_branch_replied())) {
if (ds_next_dst()) {
# XXXX SETTING HEADER AGAIN!?!
append_hf("IMP-annc: $avp(announcecode)\r\n");
append_hf("IMP-mandate: $avp(mandate)\r\n");
append_hf("IMP-language: $avp(callerlang)\r\n");
if ($avp(debug) > 0) {
xlog("L_INFO", " --> $cfg(route):
retargeting request to $ru to location $du \n");
}
# Trigger failure route again
t_on_failure("DISPATCH_MEDIA_FAILURE");
t_on_reply("DISPMEDIA_MANAGE_REPLY");
route(RELAY);
exit;
}
route(ANNOUNCEREPLY);
exit;
}
}
I know about how Kamailio works by reading header from an 'input buffer'
and writing to an 'output buffer'.
I guess in case of t_on_failure the complete output buffer with corrected
$ru and additional header is being discarded so I have to do all changes again?
