    Hi All,
    I am completely new to 3CX, and to configuring phone systems in general.

    I have a couple of questions.
    1. If I use the Skype for SIP service, and configure Skype for SIP as a VOIP provider, do I need to use the Skype Gateway.
    2. I have assumed that the answer to 1 is No, and have gone ahead and configured Skype as a VOIP provider. I am able to make outbound calls with no problem, but can't figure out what exactly is going on with the inbound calls from Skype. I have a single channel from Skype, and have configured the Skype Port to alllow 1 simultaneous call. When I call the external SKype number it rings a couple of times, and then hangs up as busy. I sometimes get a brief blip on the phone that the VOIP gateway is routed to.
    The log file for a single call coming in is below:

    08:47:43.548 [CM503008]: Call(2): Call is terminated
    08:47:43.282 [CM503025]: Call(2): Calling Ext:Ext.10@[Dev:sip:10@]
    08:47:43.204 [CM503004]: Call(2): Route 1: Ext:Ext.10@[Dev:sip:10@]
    08:47:43.204 [CM503010]: Making route(s) to <sip:10@>
    08:47:43.189 [CM503020]: Normal call termination. Reason: Disabled by Inbound Rule
    08:47:43.189 [CM503019]: Call(3): Rejected! Line is 'Busy' because number of simultaneous calls per line Anonymous@(Ln.10000@Skype) is limited by Administrator
    08:47:42.735 [CM503012]: Inbound out-of-office hours rule (unnamed) for 10000 forwards to DN:10
    08:47:42.720 [CM505003]: Provider:[Skype] Device info: Device Not Identified: User Agent not matched; Capabilities:[reinvite, replaces, able-no-sdp, recvonly] UserAgent: [sipgw-1.0] PBX contact: [sip:99051000003791@]
    08:47:42.720 [CM503001]: Call(2): Incoming call from Anonymous@(Ln.10000@Skype) to <sip:10@>
    08:47:42.189 [CM503012]: Inbound out-of-office hours rule (unnamed) for 10000 forwards to DN:10

    My understanding of the log suggests that somehow there seem to be two calls in volved (Call(2) and Call (3)). Call 3 gets rejected because of the rule regarding only one simultaneous calls.

    I don't understand enough to be able to do any kind of sane troubleshooting, so if anyone could point me in the right direction, I would appreciate it.

    Yes, it looks like the one incoming call is being handled as two. You can try setting the logs to Verbose, that might (but not always) give you some more info to go on. If you want to delve into it you could Wireshark the incoming call and see what Skype is sending and why it is being interpreted that way.

    As the log is missing earlier info, is there another instance of this line?
