Please answer me if my question have some sense. <br><br>I have recently implemented an asterisk server with freepbx. I have created 100 extentions and i can make successful calls between extensions from anywhere. But my office have three different land-line numbers and three of them are terminating into an internal PBX ( normal matrix telephone PBX) with more than 60 extensions. This internal PBX is the live PBX where we can call local, STD and ISD from extensions. <br><br>At present i have some practical difficulties to configure telephone lines at the end of asterisk PBX. So i am trying to connect my asterisk PBX to the normal telephone PBX.<br><br>I have installed 1 port x100p FXO card in my asterisk PBX and detected by my freepbx. Then i removed my normal telephone extension cable from phone and connected to the FXO port of my asterisk PBX. <br><br>Ultimately my intention is that <br><br>1) if somebody call to my normal telephone extension, that should reach to my asterisk server, and asterisk server should send this call to my asterisk extension. <br>2) if i am calling from my asterisk extension, call should go to the normal telephone PBX via FXO card in my asterisk server and ultimately the call should send outside via the telephone PBX.<br><br><br>Is my approach is correct ? If it is wrong please somebody assist me to connect my asterisk PBX to normal telephone PBX.<br><br>Michael.K<o:p></o:p></p><p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D'>The approach sounds right IF your legacy PBX phone is a simple analog phone.
