I have a TAPI based dialers using a telephony hardware such as modems. telephony cards etc.

MJ USB stick simulates the dialtone so by hooking the PC modem to it, I use a software that is capable of making the outgoing calls but it is blind in regards of the call progress.

Specially I need to know, when the other side as first disconnects the call.

My understanding is that mj is using SIP for signalling. If I could intercept (monitor) SIP messages that will do the job.
My problem right now is that I cannot even confirm that mj uses SIP.

Yes, if you read a little bit, you will find that mj dongle uses SIP authentication but the credentials are pretty hidden. With a program like Wireshark, you can capture all SIP transactions (as well as the RTP voice packets if you care to) which would probably suit your needs.
