Hello guys,

So i've setup kamailio 5 with wss. Registration goes ok, but when trying to call, SIPML as well as jsSIP send garbage as Contact header, something like:

Contact: <sip:0ku6du26@7j65fcf53i2k.invalid;transport=ws>;reg-id=1;+sip.instance="<urn:uuid:8b49ac42-2039-4122-9f5b-6f4e9f471f52>";expires=600

so when it passes through:

if (is_method("REGISTER")) {

fix_nated_register();

} else {

if (!add_contact_alias()) {

xlog("L_ERR", "Error aliasing contact <$ct>\n");

sl_send_reply("400", "Bad Request");

exit;

}

}

(taken from several examples i've found around)

add_contact_alias() fails because it tries to find whether the ip address in the contact header is different from the received ip, and if not, it adds the received ip as a parameter... so the call doesn't work...

I assume there's a way around this, can anyone help?
