[Asterisk-Users] RE: Sip Ports

[Gene Willingham]

I believe that this message is a failed MWI for voicemail.  I get them on
Cisco phones that have not been configured correctly.  It also could be an
indication of a NAT issue.  The NAT device is shutting down the ports for
the client, and the MWI message could not be delivered.  

The reason I believe it is a MWI is the message says "Non-Critical Response.
You could be getting messages that say "Critical Response", if so these are
failed inbound calls to the device.  If you give a little more information
about which SIP device, whether it is NATed or Not, whether you have send
similar messages that say Critical Response, we could give more information
about how to debug.
