[SR-Users] Server silently droping Bye message.

[Helena Garcia-Nieto]

Thanks again Daniel

 

I've been reading deeply the module info and learning a lot. Your easy
solution worked thou, using the subst_hf  function instead of the normal
subst the alias is added correctly and then the following bye is also
correctly handled.

The final line I use is:

subst_hf("Contact", "/>.*$/>/", "a");

 

Thanks again for this great user mailing list! And for the kamailio itself

 

BR,

 

Helena

Thanks! Thank you very very much for your help.

I'll add the ngrep next time!

 

I'm absolutely new at kamailio and I'm doing the Subs on the main config
file (/usr/local/etc/kamailio/kamailio.cfg) on the PSTN call detection
route[PSTN] {:

 

if(!($rU=~"^(\+|00)[1-9][0-9]{3,20}$"))

                return;

                # only local users allowed to call

                if(from_uri!=myself) {

                               sl_send_reply("403", "Not Allowed");

                               exit;

                }

                if (strempty($sel(cfg_get.pstn.gw_port))) {

                               $ru = "sip:" + $rU + "@" +
$sel(cfg_get.pstn.gw_ip);

                } else {

                               $ru = "sip:" + $rU + "@" +
$sel(cfg_get.pstn.gw_ip) + ":"

 
+ $sel(cfg_get.pstn.gw_port);

                }

 

# modifications to acces env5

subst_uri('/^sip:00(.*)/sip:\1/i'); #append delete the 00

subst('/^Contact: (.*)>.*$/Contact: \1>/i');#delete the parameter that is
anoying env5 on contact header

 

And I cannot find the msg_apply_changes(); part on that file, can you tell
me where I can better do the subs, in which file?

msg_apply_changes() is not used in default config file, you have to add it
yourself -- it is part of textopsx module which is loaded in default config
file -- see its readme for more details.




 

I'm not actually moving the > just droping everything after it.


Better said, you remove the contact header and then add only the part up to
>, but the operations done inside are a bit different than people would
might expect, by using data lumps (if you search in mailing list archive you
can find more details).




 

I'm sure there is a better option to change the contact header, would you
have any suggestion?

You can give a try with:
subst_hf("Contact", ">.*$", ">");
but might result in same troubles, because alias parameter is added after
this operation. So you have to use msg_apply_changes(). But don't forget to
move the record_route() after msg_apply_changes().

Cheers,
Daniel
