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
