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!

Re: VVX 500 Sip Trace Log

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.
