VVX 600 cannot resume call after call placed on hold


VVX 600 cannot resume call after call placed on hold

I am using VVX 600 and when I place a call on hold (or attempt to conference in another call) the call cannot be resumed. 


I am running on UC Software Version


I have read through 2 threads on the subject [] and [], and neither has provided a solution. 


For the first thread, I cannot find the parameter referenced ("feature.moh.payload") in the configuration files. 


For the second thread, I ended up with no solution like the OP there. 


Someone please help me figure this out. If there is any information that I need to provide in order to get some suggestions, let me know. My voip provider hasn't been helpful because the do not sell this phone. It provisioned instantly and works fine other than this issue. But this hold situation is not cool.

I forgot to mention, that for whatever reason, when the call is an incoming call, the caller will hear music while on hold but when I attempt to resume the call it's silent - they can't hear me and I can't hear them. 


When the call is an outgoing call, the person won't hear any music while on hold and when I attempt to resume the call it's remains silent on both ends.

Hello DB13,

welcome to the Polycom Community.




The above ws introduced in UC software 5.3.0 and to my knowledge is only for Skype for Business / LYNC.


I suggest you try to follow this:

Resolution: Please check => here <=

If you cannot see any errors I suggest you bring this to the attention of support.

In order to raise a support ticket you need to work with your Polycom reseller as they need to do this for you.

If this is some sort of an Internet discounter please post either your phone's MAC address or your Polycom devices serial so I can look up who would be able to support you.


If your unit is out of warranty the next option is PPI / Pay Per incident.

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