    Hello,

    I have just installed a SP3102 VoIP router together with 3CX. I have also configured a digital receptionist with a language selection. Depending on the select 1-2-3 the call is forwarded to a different internal extension. The incoming landline is set to go to the digital receptionist extension when a calls come in.

    When I now make a voice call from my mobile phone to the landline (which is connected to the VoIP router and linked to a digital receptionist), I can make the selection in the digital receptionist, and the call is correctly transfered to the correct extension, but when I hang up my mobile (without picking up the phone internally) to terminate the test, the incoming PSTN line stay 'Connected' in 3CX.

    Even when I reset my VoIP router is stays connected. When I call my landline again, I get the busy tone. The only solution to this is to restart all 3CX services.

    What can be the reason for this and how can I resolve this?

    Thank you!

    The call clearly is not hanging up from the 3102 back to the landline. When you clear the call, the landline should send back a CPC signal (disconnection for only say 100ms) to tell the equipment to disconnect the call. In addition, a tone can be sent back through the landline to show that the call is cleared. I am not sure where you are from, so cannot tell you exactly what the parameters should be.

    The 3102 has no way of knowing about disconnecting the call unless the CPC or tone signal is used. The call is therefore held up as the loop stays on the line. Eventually it will release. Some administrations use polarity reversal - particularly if it is a business line.

    I hope that will help.
    Kind regards

    Hello,

    I am from Belgium. It is a standard PTSN line.

    I have used the first part of this procedure: http: //www.3cx.com/voip-gateways/linksys-3102/ - NO LONGER AVAILABLE
