Hi! I´ve configured an elastix PBX with an OpenVox B200E with 2 ISDN. I´ve tested it on 1 ISDN channel but I get strange results. If someone phone me, the calling is stablished without any problem. Nut if I phone someone (outbound)I get a message form my telephone company telling me the line is busy, so I understand the call go outside. Is that a normal way to work? Should I have 2 ISDN lines for well working? Is it possible to configure my elastix for just one ISDN line with this card? Thank you.
