[SR-Users] Issue with app_perl - return value, logging and append_branch

Hi All I may well be me missing something obvious but I have got three odd ones whilst trying to test app_perl module which I'd appreciate some assistance with. Setup -------- Kamailio version : 4.0.0 (x86_64/linux) from Peter Dunkley's YUM Repository Perl version : v5.10.1 OS version : CentOS release 6.4 Kamailio.cfg highlights; loadmodule "app_perl.so" modparam("app_perl", "filename", "/tmp/test.pl") modparam("app_perl", "modpath", "/usr/lib64/kamailio/perl/") # ** would someone like to add the app_ to 5.1 and 5.2 of the manuals please request_route { . . route(PERL); . . } route[PERL] { if ($rU=~"^124" && method=="INVITE") { xlog("L_INFO","perl: match $rm $ru from:$fu ($si:$sp) to:$tu rpid:$re\n"); if (perl_exec("testrouting")) { xlog("L_INFO","perl: true exit\n"); } else { xlog("L_INFO","perl: false exit\n"); } } } /tmp/test.pl has the following in it ... #!/usr/bin/perl use Kamailio qw ( log ); use Kamailio::Constants; use Sys::Syslog qw( :DEFAULT setlogsock); sub testrouting { setlogsock('unix'); openlog($0,'','user'); syslog('info', "PERL Kamailio - Log test"); closelog; return 1; } There is no valid route for 124@ and the above works exactly as I'd expect; -> Phone sends INVITE to 124 <- Proxy responds with AUTH Required -> Phone sends ACK -> Phone sends INVITE to 124 with AUTH -- SysLog gets a "PERL Kamailio - Log test" from perl script -- Kamailio log gets "perl: true exit" <- Proxy responds with "404 Not Found" -> Phone sends ACK ------------------------------------------ First problem is that if I swap the "return 1" in test.pl for "return 0" what I see is; -> Phone sends INVITE to 124 <- Proxy responds with AUTH Required -> Phone sends ACK -> Phone sends INVITE to 124 with AUTH -- SysLog gets a "PERL Kamailio - Log test" from perl script -> Phone resends INVITE to 124 with AUTH -- SysLog gets a "PERL Kamailio - Log test" from perl script -> Phone resends INVITE to 124 with AUTH -- SysLog gets a "PERL Kamailio - Log test" from perl script -- I Hang Up Phone --> Phone send CANCEL --> Phone send CANCEL --> Phone send CANCEL In this second test once perl_exec is called all routing seems to stop. There's nothing from the xlog to say if perl_exec returned true or false. -------------------------------------- The second problem I have is when I add "Kamailio::log(L_INFO," line it never arrives in any of the logs use Kamailio qw ( log ); use Kamailio::Constants; use Sys::Syslog qw( :DEFAULT setlogsock); sub testrouting { setlogsock('unix'); openlog($0,'','user'); syslog('info', "PERL Kamailio - Log test"); closelog; Kamailio::log(L_INFO, "PERL : testrouting\n"); return 1; } -------------------------------------- The third one is that I cannot get append_branch to do anything. If I add to the perl script the lines; my $m = shift; $m->rewrite_ruri("sip:anotheruser\@ourserver"); The call gets diverted as expected. However if I use append_branch; $m->append_branch("sip:anotheruser\@ourserver"); It has no effect at all. -------------------------------------- That's as far as I have experimented with the module so I can't say if everything else is working as expected :-) Anyone have any thoughts?
