Hi ppl,
I have this problem with call transfer, may be someone can help.
The phone to the far right is registered with the Registrar to the far left
using two PATH headers (trespassing two proxy ports, 5070 then 5060).
As you can see in the graph below, after receiving the UPDATE request,
Kamailio relays it further from port 5060, I expect it to be from 5070 just
like the dialog forming INVITE and the CANCEL afterwards.

The UPDATE has a to-tag, but unlike the original INVITE - it has no Route
header!???
route[*WITHINDLG*] {
if (!has_totag()) return;
if (loose_route()) {
route(DLGURI);
if (is_method("BYE")) {
...
}
else if ( is_method("ACK") ) {
route(NATMANAGE);
}
else if ( is_method("NOTIFY") ) {
record_route();
}
route(RELAY);
exit;
}
if ( is_method("ACK") ) {
...
}
# handle UPDATE method for in-dialog requests
if (is_method("*UPDATE*")) {
route(DLGURI);
record_route();
route(RELAY);
}
}
Thanks in advance.
