Matrix: Can I use my Eclipse matrix and dial out using DTMF to a 3rd party telephone hybrid?
Yes it is possible to connect to 3rd party telephone hybrids (POTS/ PSTN/ ISDN/ VOIP/ SIP) to your Eclipse matrix and dial out using DTMF tones from the matrix MVX-A16 port.
Note: the 3rd party telephone hybrid must support DTMF decode / encode
Detailed solutionTo produce a DTMF signal from an MVX-A16 card set theport function to a TEL-14, and then latch a key to the port and dial from a panelor use a speed dial. There's no need to connect a TEL-14, it's just a handy wayto make the system behave as you need. Thetrick is to make the Eclipse believe that something is connected, and there aretwo ways of doing that: 1)Turn Hardware Detect (Cards and Ports > Advanced Settings) OFF. Ifyou don't have this option in the ECS / EHX version you're using: 2) From the matrix MVX port . Make a cable with an RJ45 connector that loops back pins 1 to 7, 2 to 8 butleaves the other pins alone. I find the EZRJ connectors (http://ezrj45.com/ezrj45plugs.php?gclid=CNW35ob-vrkCFSlo7AodxhUAqg)make this easier to achieve.The other RJ45 pins 3+6 and 4+5 are the balanced 4wire audio lines to/ from the matrix
