Troubleshooting Notes, Cause Codes | Polycom VS4000 guide

Troubleshooting Notes

When a system places or receives an ISDN call, the events during the call sequence generate diagnostic codes. The Q.850 standard defines these codes.

The ViewStation EX, ViewStation FX, and VS4000 systems capture some of these cause codes — such as the reason for call disconnection — in the Call Detail Report. Other codes cause the systems to display error messages. The Q.850 codes can be used to isolate and diagnose unexpected system behaviors.

Q.850 Cause Codes

The following table describes codes that the ISDN switch sends to the router to indicate call status. Although the codes are standardized, each ISDN service provider defines them differently. Because of this, the definitions in the table may not exactly match the messages that you see.

Code	Cause	Definition

1	Unassigned number	The switch received the sent ISDN number in the
		correct format, but no destination equipment uses the
		number.

2	No route to specified	The ISDN exchange does not recognize the
	transit network	intermediate network through which to route the call.

3	No route to	The intermediate network through which the call is
	destination	routed does not serve the destination address.

	unacceptable	service quality to accept the requested connection.

7	Call awarded and	The user is assigned an incoming call that is being
