I have it working somewhat now but I notice on the wire that the content-length is zero. It's supposed to be the size of all the custom headers from what I can tell from the RFC. Is there a standard way of setting this? Also, I'm not getting the notification from ClientSession::OnIncomingSIPMessage when the server sends back it's status 100 "Trying" packet (see capture below).
Here's what went on the wire. It shows an Internal Server Error but I'm not sure it is from the content length being zero. In the last version of the MWI service, I wrote my own SIP commands to do this, I found that I had to use Invite to get it to work even though Dialogic Support was telling me that they accept Notify and they reminded me that Invite may go away since it is not the standard. I just assumed that it was because I had written my own SIP commands to do it. I'll keep at this and maybe try it against our Cisco CM to see how it behaves.

Subject: Re: [OpenSIPStack] MWI Notify
Hi Bill,
Download the latest OpenSIPStack from CVS. There should now be a
sample/client_server_demo directory. It contains the skeleton code for client and server UA. I've used unsolicited MWI notify in the client to
better serve your purpose. Here is the snippet from the Main() function.
It basically creates two user-agents bound to 5060 and 5070 respectively and
let the client (5070) send MWI notify to the server(5060). You can get the
response in OnIncomingSIPMessage of the client session. I also pasted the
snippet below. Feel free to submit a tutorial based on your experience
with this code.
HTH,
Joegen
