Thanks Daniel, couldn't have asked for more.
Daniel and Alex, one further question... (theoretical, since I'm yet to try
this out) -
Would Kamilio also take care to send out the ACK to end the trasaction with
B-party, and continue the relayed transaction with C-party ?
Is this, in effect same as serial forking ?
Apologies for questions that are perhaps more to do with SIP, than Kamilio
itself.

URI) ?
No problem, if you take a look at the "default" config it will have a
failure_route[MANAGE_FAILURE] and a WITH_BLOCK3XX define commented.
The failure route will normally block 302:
# block call redirect based on 3xx replies.
if (t_check_status("3[0-9][0-9]")) {
send_reply("404","Not found BLOCK3XX");
exit;
}
If you replace (or insert before) above code something like:
if (t_check_status("302")
{
$var(contact) = $T_rpl($ct);
$var(contact) = $(var(contact){re.subst,/^<(sip:\+?
[0-9]+@.*)>$/\1/});
$du=$null;
$ru=$var(contact);
route(RELAY);
exit;
}
You have your case solved.
BTW you might want to do additonal checks when billing is concerned.
