Good afternoon,
I have an NMS open source telephony unit that is using PRI 5ESS to connect to a 3300 using QSig.
The 3300 is the QSig side with address A.
The trunk comes up, D channel comes up. When I call from the NMS to the 3300, the desk phone actually does a split second "blip ring" then the NMS gets a call hung up message from the 3300.
I've checked all the call timers, made sure the Call Duration Forced Cleardown Timer is set to 0.
The extensions can call each other just fine.
Any ideas why it would drop the call just as soon as it makes the phone ring?
