VVX 500 Sip Trace Log

This is a Sip trace Log from the VVX500 ( 

A break down of this log would be fantastic.  This log shows call A coming to the phone, Answered, Placed on Hold,  a second call coming into the phone, answered, and when we try to use the Soft key to emulate a call park or the basic transfer we have a failure.

With a single call initiated on the phone we can complete this all day long.  The issue is when there are 2 or more calls on the phone we have failures transfering and parking.   


Any help would be great!

Hello Nate27,

welcome to the Polycom Community.

The community's VoIP FAQ contains this post here:

Jan 19, 2012 Question: How to troubleshoot Polycom VoIP related Issues?

Resolution: Please check => here <=

You log is not in debug and when briefly looking over it I can see a 487 Message.


Not knowing who your SIP provider is I can only suggest you work with their team to troubleshoot this. You should also use a currently supported software version like 5.5.2 or 5.4.6

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards
