This presentation was intended to present theoretical and experimental concept during setting up a VOIP Server with the well known open source VOIP Server Asterisk@home. Here we have implemented GnuGk PBX and at the last phase we have configured Asterisk server. This was presented at ICACT2007.

  2. 2. Small Office PBX using Voice Over Internet Protocol Presented by: Saugata Bose 4 th year 2 nd semester, CSE Department, Shah Jalal University of Science and Technology, Sylhet
  3. 3. Covered Topics <ul><li>VOIP overview </li></ul><ul><li>Project Objectives </li></ul><ul><li>Implementation and Configuration </li></ul>
  4. 4. <ul><li>VOIP </li></ul>“ V”oice “O”ver “I”nternet “P”rotocol <ul><li>How VOIP works? </li></ul>Analog data -> ADC -> Internet -> DAC ->Analog data
  5. 5. Why VOIP over PSTN? <ul><li>Flexibility </li></ul><ul><li>Just one internet connection and a computer or VOIP enabled softphone </li></ul><ul><li>Pricing </li></ul><ul><li>Free calls!! </li></ul><ul><li>Three-Way Calling </li></ul><ul><li>Allows to connect three people with just one call. </li></ul><ul><li>And many more…. </li></ul>
  6. 6. Project Objectives <ul><li>Small Office PBX using Voice Over Internet Protocol </li></ul>We implemented this .
  7. 7. VOIP Signaling Protocols <ul><li>Session Initiation Protocol (SIP) </li></ul><ul><li>H.323 Signaling Protocol </li></ul><ul><li>Media Gateway Control Protocol (MGCP) </li></ul>Three signaling protocols So which we will choose????
  8. 8. Our Choice…… <ul><li>The mighty </li></ul>Asterisk @ Home
  9. 9. Up coming….. <ul><li>Configuring Incoming & Outgoing Services </li></ul>
  10. 10. Components <ul><li>IP-PBX </li></ul><ul><li>Soft phone </li></ul><ul><li>Gateways </li></ul>
  11. 11. Components of the Asterisk Server <ul><li>A fully dedicated PC </li></ul><ul><li>Fully duplex sound card </li></ul><ul><li>Sufficient Bandwidth </li></ul>
  12. 12. Gateways <ul><li>VOIPJET </li></ul><ul><li>Broad Voice </li></ul><ul><li>VOIPJET is used for outgoing calls Broad Voice is used for incoming calls </li></ul>
  13. 13. Sign up for the Service <ul><li>Sign up in VoipJet </li></ul><ul><ul><ul><li>Log on there </li></ul></ul></ul><ul><ul><ul><li>Then I will get an account name and password </li></ul></ul></ul><ul><ul><ul><li>They will give you the IP address of the server </li></ul></ul></ul><ul><li>Same is true for Broad Voice </li></ul>
  14. 14. Set up the SIPPhone User Name: 200 Password : abc123 Domain : 192.168.0.40
  15. 15. Costing <ul><li>We have cheaper cost setup than general PBX </li></ul><ul><li>We need 9 dollar as activation fee. </li></ul><ul><li>We need 5$/month for incoming charge if we use Broad Voice </li></ul><ul><li>We need 1.3 cent/minute for outgoing if we use VoipJet. </li></ul>
  16. 16. Up coming….. <ul><li>Configuring Asterisk@Home </li></ul>
  17. 17. How can I make calls using Asterisk?? <ul><li>My phone no. is 938260 </li></ul><ul><li>The other person’s no. is 123456(+200) </li></ul>
  18. 18. How can I make calls using Asterisk?? <ul><li>Process1: </li></ul><ul><li>Configure </li></ul><ul><li>/Trunk.
