Resume the on hold call makes phone cannot hear the caller, but the caller can hear us



I have a problem with music on hold. I have polycom VVX601, VVX501 and Trio 8800. I login as a skype for business users.

Received an incoming call - no problem.

When i put the caller on hold, the caller hear music on hold as normal, but when i resume the call, i can't hear the caller anymore, only the caller can hear me. It use the latest firmware.


I check with my gateway vendor, he mention that polycom phone media sent during on hold is "sendonly" thats why it didnt work.

While if i login on my desktop client, then do the same call, hold call, resume, will works as normal because the media sent during on hold is "sendrcv".


Anyone able to advise how to solve this? And workaround Disable MOH is not applicable in my environment here.

Hello Steven,

welcome to the Polycom Community.

It is always useful to include the currently used UC Software version as issues experienced or a question asked may already be addressed in a newer release.

This also allows yourself and others to check against current software release notes, Administrator Guides or FAQ post’s.

The above is also stated in the "Read First"

Therefore the Polycom VoIP FAQ contains this post here:

Question: How can I find out my SIP or UC Software Version of my Phone?
Resolution: Please check here


The above is the minimum requirement for a new post.

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

Best Regards
