After connecting BRI cable, then you can go to page 'PBX monitor > Trunks' to check the BRI trunk status. Below two situation are the BRI trunk physical layer didn't go through.

If getting above problem, then you need to configure BRI trunk on page 'Settings > PBX > Trunks > Edit > Basic'. Also make sure the BRI Carrier side enabled the BRI trunk.

    Hi Gary,

    You did a great job with this article. I have a little problem with an ISDN line that has 2 numbers. How can you make an S20 to manage the 2 numbers (ie. 0438111111 and 0438222222). When an outside call gets the ISDN line, number 0438111111 has to make ring a calling group, and number 0438222222 has to go to extension 210. I tried with DID but didn't work. Do you have any idea? Thanks.

    Best regards,

    Walter De Stefano.

    The picture shown in the table is a typical RJ12 but you can use also a RJ11 cable.

    1. RJ11 and RJ12 wiring uses the same six slot connector
    2. RJ11 and RJ12 only differs in the wiring
    3. RJ12 utilizes all six slots while RJ11 only uses four of the six available slots
    4. RJ11 and RJ12 are commonly used for telephone systems with RJ12 being used in different configurations
    5. RJ11 is very common in today’s homes while RJ12 is quite uncommon except in some large companies

    ----------------------------------------------------------------------------------------------

    The other pictures show a RJ45 cable.

    So If I buy a Rj11 -> R42 cable the line order is already correct?
    I have not the equipment to do the physical configuration.

    You can choose a RJ11 cable :

     

    or a RJ12 :

     

     

    Remember in a RJ12 cable the first (pin 1) and the last (pin 6) slot are not used.

    They are both correct to use if you buy in a shop.

    Thx alot for yout help. I was dumb I forgot to buy the B2 module, somehow I thought it was included.

    Everything is working now except one thing, when I call someone it only show one number 123456-0, I got the number range from 0-99. I tried to set it up that it show the number 123456-30

    I tried to set it up in Connection->Bri->DoD
