That does not work: presence_server always uses the original received
body, the modifications applied by you are not seen by the presence server.
The workaround would be to "loop" the modified PUBLISH to Kamailio
again, e.g.:
listen=.......:5060
listen=.......:5050
route{
...
if (is_method("PUBLISH")) {
if (dst_port==5060) {
subst_body('/group1[.]//');
t_relay("udp:127.0.0.1:5050);
} else if (dst_port==5050) {
handle_publish();
t_release();
}
}
...
}
