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.
