Hello Daniel,

 

No action executed related to app_perl. I have tested with the following configuration:

 

# -------- dialog params -------

modparam("dialog", "dlg_flag", DLG_FLAG)

 

# -------- cnxcc params --------

modparam("cnxcc", "dlg_flag", CC_FLAG)

modparam("cnxcc", "credit_check_period", 1)

 

# --------- app_perl params ----

modparam("app_perl", "filename", "/usr/local/etc/kamailio/AAA/aaa-script.pl")

modparam("app_perl", "modpath", "/usr/local/lib64/kamailio/perl/")

 

Then, in Kamailio.cfg, nothing called the app_perl module.

 

The INVITE is coming with one Via header. Then, the call is routed to a gateway and when Kamailio append the forked INVITE with his Via header, he is malformed.

 

If I print "route[RELAY] {

        xlog("ENTERING RELAY routes: $(hdr(Via)[*])\n");" the result is fine in the log. But looking at a tcpdump, I can see that the outgoing packets has a malformed Via header.

 

Regards,

 

Igor.

Hello,

this should not happen -- is any config action executed, or this happen before first action in request_route being executed? You can add an xlog there to see if it is executed.

Cheers,
Daniel

Hello,

 

Someone experienced the same issue? I test again and I'm sure that it happens when I load and setup the module app_perl. Even if it's not used into the config file.

 

Regards,

 

Igor.

Objet : app_perl modifies Via header?

 

Hello,

 

I try to use app_perl and cnxcc module.

As soon as I load the module like this:

 

# --------- app_perl params ----

modparam("app_perl", "filename", "/usr/local/etc/kamailio/AAA/aaa-script.pl")

modparam("app_perl", "modpath", "/usr/local/lib64/kamailio/perl/")

 

The Via header is modified for each calls:

/usr/local/sbin/kamailio[21064]: INFO: <core> [parser/msg_parser.c:355]: parse_headers(): ERROR: bad header field [Via:ASIP/2.0/UDP 91.]

/usr/local/sbin/kamailio[21064]: ERROR: <core> [parser/parse_via.c:2048]: parse_via(): ERROR: parse_via: bad char <A> on state 100

 

What could explain this behaviour?

 

Regards,

 

Igor.
