[FAQ] How can I enable MoH for my VVX Phone using LYNC ?

UC Software 5.3.0 added the ability to enable Music on Hold for the VVX Business Media Phones once the phone is in LYNC base profile.


The default MoH file size is 540 KB (Polycom-hold.wav) included when downloading the UC Software from the Polycom support server and the maximum file size is 600 KB.


You can use the parameter res.quotas.tone to increase the maximum MoH file size to 1024 KB.


The phone supports the following .wav audio file formats:


  • mono G.711 (8 bits/sample, 8-khz sample rate)
  • mono L16/16000 (16 bits/sample, 16-kHz sample rate)
  • mono L16/48000 (16 bits/sample, 48-kHz sample rate)


You can upload a music file to the phone using the phone's Web Configuration Utility at Preferences > Additional Preferences > Music On Hold





The feature.moh.filename Parameter can be utilized to provision a MoH file matching the above requirements from a provisioning server.
