  1. PROJECT ProposalTopic: Capacity planning model using SIP and IAX with G. 726 and ILBC By: Vishal and Anoosha

  2. Earlier work • Two asterisk servers • Signaling Protocol : SIP and IAX • Codecs : G.711 and GSM • Vyatta Router used • Sip.conf, Iax.conf and extensions.conf • .call files for 30 calls in asterisk server 1 • Packet analyzer: Wireshark . Theoretical and practical were compared

  3. Repeatability • How can we repeat using SUNYIT infrastructure???????? • Two asterisk server within same network in VM’s • Digium Hardphones • Configuration files : sip.conf, iax.conf ,extensions.conf • .call files for 10 calls in asterisk server 1

  4. Extendability • Signaling Protocols: SIP AND IAX • Codec used : G. 726 and iLBC • SIP and IAX trunking is done • Dialplan is configured so that two asterisk servers can communicate • call from 2 hardphones to calculate per call bandwidth. • “.call” files for 10 calls will be configured to generate 10 calls simultaneously.

  5. Extendability cont.…. • Packet Analyzer: TCP dump will be used to capture packets • Captured packets will be analyzed in Wireshark. • Per call bandwidth is analyzed • Bandwidth for 10 calls is analyzed • Theoretical bandwidth values will be calculated using online tools • Practical values obtained by experiment will be compared.

  6. Use of this project • Understanding different options in terms of Signaling protocols used. • Understanding the functionality of the codec used. • This work will help to refer for capacity planning while creating a new VoIP network
