Hi there. We have IP Office 500 v2 9.0.5.0 with an external music on hold source. When I dial *34, MOH is loud and clear. When I call in from outside and put the call on hold, MOH volume is much lower than *34, but you can still hear it somewhat. When I call in from outside and am in queue for a hunt group we created, MOH (played between announcements) is lower still; it can barely be heard at all. Any ideas as to why the volume would be so low, particularly when in queue for a hunt group? Thanks in advance.
