On Hold music not played sometimes (in Queue)

On Hold Music, when in a queue, is not always played.

A caller joins the queue, hears the 'join-announcement', and then hears nothing. Resulting in the caller hanging up, because he thinks the line went dead.

The caller cals back, and its working.
So nothing changed in the mean time.

Any idea what can cause this?

Is the caller dialing via the PSTN directly, a VoIP trunk, or another SIP URI?

Well, It doesn't matter.

Sometimes it happens with a VOIP-call, sometimes not.
It also happened when I tried to call my number with my cellular phone.

But the strange thing is that sometimes it works, 2 minutes later not anymore.
