Hi all, every now and then my test setup is suffering under a weird problem with a call queue. Up till now I am unable to resolve it. I'm hoping one of you has encountered this before and knows an answer. The problem arises when there's an incoming call to a call queue. The call queue is configured with a custom MP3 intro prompt followed by a custom MP3 for the on hold music. Every now and then, the intro prompt gets played multiple times. It starts off by playing the intro correctly and the phones in the call queue start ringing. Then the on hold music starts. After one or a few seconds the intro file gets played again while the on hold music is still playing on the background. This can occur multiple times and the repeating sometimes occurs before the intro prompt has finished playing. When this happens, usually the configured 60 seconds wait time is not met either and the destination if no answer action is performed after approximately 20 seconds already. It only occurs when having an incoming external call. It doesn't matter if this is through a Linksys SPA3102 device from a PSTN line or directly from a VOIP provider into the 3CX. It never happens when using a phone directly connected to the 3CX PBX and calling the call queue. It doesn't seem to make a difference if there are just two agents active in the call queue or more. I've had this weird experience in 3CX PBX v7 and now also in 3CX PBX v8 beta. The logs show no weird things. Also not under verbose mode. It does show the call being forwarded to the "destination if no answer", but it shows no reason for doing this before the configured 60 seconds timeout. I can't figure out when it does work correctly and when it doesn't. I have attached the verbose output of the 3CX PBX during an incoming call where this problem occurs. I have 3CX installed on a virtualized instance of Windows 2003 Enterprise Edition with Service Pack 2 running on the HyperV platform with Windows 2008 R1 Enterprise with Service Pack 2. I already lowered the amount of virtual CPU cores to one to make sure that's not causing any problems. It doesn't resolve the problem. Memory and CPU availability do not seem to be causing the problem. Does anybody have a clue how I can resolve this issue? Thanks in advance for any advice you may be able to give!
