[SR-Users] Can following scenario be implemented using Kamilio

[Jayanth Acharya]

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.
