Sorry for telling you this, but if you think that, you don't know Asterisk at all.
You don't need to send a REINVITE to put a call on hold, just change how you handle
the RTP of the call if you SIP endpoint doesn't support REINVITES/UPDATES.
Asterisk knows about presence, it doesn't have full implementation, but you either
need it.
Also transfers doesn't force you to do them throught REFERS

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. If not, can anyone suggest something else which
could sit in between a
very basic SIP client and a PBX server, in order to inject these sorts
of commands into the path and thereby give me these sorts of extra call
capabilities?
This really sounds like a better use case for Asterisk, FreeSWITCH,
SEMS, or PJSIP. Can you point me at anything which documents how this
could be possible?
The thing you need it's a B2BUA, and Asterisk, FreeSwitch, YATE, SEMS, either a simple
python
script using pjsua2 or any of the dozens SIP frameworks out there, will allow you to
acomplish
your goals
If you go the Asterisk road, any of the AMI/ARI documentation will explain to you how to
handle
ongoing calls.
If you prefer FreeSwitch, you will have to surf the ESL seas.
I you take the SEMS aproach, SBC + DSM/Python/xmlrpc
You could take any road you like, but not Kamailio, as it's not a B2BUA.
I suggest you, first undestand the concepts you need to manage, then you will be able to
pick
up a tool for solving the problem.
