Not sure what SSA is?
I managed to take care of it. What I did was add ad DROP button to my phone through IP Office Manager, dialed into the conference call, hit the Drop button, chose the number on my display and the cooresponding button to drop. That did it!
Wow, that was not good! I guess that's another thing to add to my plate, keeping track of open lines on our system with the CallStatus utility.
Thanks for your reply Tom! I appreciate it.
