I've found this on the GXP-2000 configuration guide.

NOTE: Music on Hold will not be played internally when a call involving a Grandstream phone is placed on hold. To fix this behavior you will need to access the 3CX Management console, Edit Extension, click on 'Other' tab and perform the following changes:

Uncheck Supports Re-Invite (This will automatically disable 'Replaces')
Check PBX Delivers Audio

WIll try it out.

This will fix the problem for sure.
Grandstream have promised us a fix for this in the near future.
