I know Asterisk pretty well.

When you use it as a SIP client to register to another PBX, it is extremely 
basic - it can place a call and it can receive a call, but it has no concept 
of presence, it cannot send a REINVITE to put a call on hold, it cannot send a 
REFER to transfer a call...

I don't understand how placing this in between my simple client and the PBX 
which is handling the call can possibly inject the commands I need.

Can you point me at anything which documents how this could be possible?


Thanks,


Antony.
