Hello guys,
I'm listening on port 443 for tls and 5111 for tcp.
Client registers on 443 and makes a call over tls which kamailio forwards
over tcp.
Because freeswitch doesn't support "sips" yet, when replies come back from
freeswitch (which contact set as "sip:" i manually change that tp
"sips:"
for the client to not die with "SIPS Required".
Call is established and the client responds with ACK. At this point i need
to change back the contact "sips:" to "sip:".
This is the route that changes it:
route[FIXCONTACT] {
# This is freeswitch sending a message, so we change "sip:" to
"sips:"
xlog("L_ERR","[FIXCONTACT]: User-Agent is: $ua\n");
if( $ua =~ "^FreeSWITCH" ) {
if( subst('/^(Contact:.*)sip:/\1sips:/') ) {
xlog("L_ERR","[FIXCONTACT]: Method $rm Status $rs Changed
contact coming from freeSWITCH from sip to sips [$ct]!\n");
}
# Else it is the client, when change it back from "sips:" to
"sip:"
} else {
if( subst("/^(Contact:.*)sips:/\1sip:/") ) {
xlog("L_ERR","[FIXCONTACT]: Method $rm Status $rs Changed
contact coming from CLIENT from sips to sip [$ct]!\n");
}
}
return;
}
When kamailio is preparing to send out the ACK via TCP I'm seeing:
[forward.c:268]: get_send_socket2(): protocol/port mismatch
And I really don't know why it's doing this...
Help is appreciated!
