Hello,
I have a question regarding the "SWITCH" statement from the core of
sip-router / kamailio.
In the news publication
(
http://www.kamailio.org/dokuwiki/doku.php/features:new-in-3.0.x) I found a
description that the switch statement now supports "regular expression for
matching string".
However, when I try the example (as displayed on the wiki page) I get
different error messages. The example that I've tested looks like:
switch($rU) {
case /^123/:
sl_send_reply("200", "yippie - ^123 works");
case /^124.*/:
sl_send_reply("200", "yippie - ^124.* works");
break;
}
Worst case was using the first case with the case label "/^123/".
That resulted in a segmentation fault (!) with following error messages:
loading modules under /usr/lib/kamailio/
0(23229) : <core> [cfg.y:3329]: parse error in config file
/usr/local/etc/kamailio/kamailio.cfg, line 374, column 16: syntax error
0(23229) : <core> [cfg.y:3329]: parse error in config file
/usr/local/etc/kamailio/kamailio.cfg, line 374, column 16: bad expression
Segmentation fault
When I added ".*" to /^123/ as in case "/^124.*/" the error message
was:
loading modules under /usr/lib/kamailio/
0(23256) : <core> [cfg.y:3329]: parse error in config file
/usr/local/etc/kamailio/kamailio.cfg, line 374, column 15: syntax error
0(23256) : <core> [cfg.y:3329]: parse error in config file
/usr/local/etc/kamailio/kamailio.cfg, line 374, column 15: bad case label
0(23256) : <core> [cfg.y:3329]: parse error in config file
/usr/local/etc/kamailio/kamailio.cfg, line 374, column 15: bad case
0(23256) : <core> [cfg.y:3329]: parse error in config file
/usr/local/etc/kamailio/kamailio.cfg, line 379, column 5: bad switch body
What does sip-router / kamailio now REALLY support? Is the information about RegEx a
mistake on the web page or is only the syntax wrong? However, in the CoreCookbook no entry
can be found regarding RegEx for switch statement......
Regards,
Klaus
