Dear all, I have set up a SPA3102 gateway with 3CX system. It is connected to an analogoue PSTN line with two numbers on the same cable pair connected to the SPA3102 line port, i.e. DIDs. To make it easier to understand, one number is 3132378 and the other is 110. It works fine with the first one and I can received calls and dial out numbers. However, when I dial in to the second number, 110, the SPA3102 does not sense the ring, i.e. the PSTN indicator in the 3CX console does not go yellow as if there is no incoming call on that line. However, when I connect that line with a telephone set, it rings and I can receive call on the second line, i.e. 110. Also, in the SPA3102 web console, the SPA3102 senses the ring on the gateway PSTN side but it does not pass it on to the 3CX system. I would be very grateful if anyone can help me solve this problem. Thanks very much.
