[Users] t_uac_dlg disconnect example - WILLING TO PAY

I need a complete example (with proper syntax) of how to disconnect a call (send BYE) using "t_uac_dlg". This can be either via bash script or openserctl command. I have been fighting with this for some time and always seem to get "Too few or to many parameters" errors. I have been through the ctd.sh example and searched the mailing list but, I'm still having no luck. I have read Jan's "SER FIFI Interface" doc, and I believe my fifo files are working properly, however I really don't know the exact syntax, or what elements are required to get this to work. I have access to the "Call-ID" as it is stored in MySQL via acc. I am willing to pay for this example. Just let me know a fair price. FYI: I am using OpenSER 1.2. Thanks, Daryl
