%NP-3-NAKRSP: NAK Response Received


Hey guys, Thanks for taking the time to read this post. I wanted to put this out here and see what kind of feedback/help/assistance I could get.  I'm a Network Admin at my company and pretty much in charge of anything Routing/Switching related. However, my boss had me look into what appears to be a VoIP issue.  I've posted the error from our Cisco AS5850 below for you to look at.  Now, everything I've found online through Cisco docs, other websites, etc., just states that this occurs when a call fails or is disconnected and that there is no work around. What I'm not able to fully grasp here is whats causing this to happen and if there has been a work around created since those docs where compiled.  If this is something that nothing can be done about, can anyone put this into perspective for me so that I know how impacting this may be or if its something that I should really not worry about. Thanks in advance!
