  • ObjectivesVoice Over IPSIPH.323MGCPSimulation using WestplanConclusion

  • Voice over IPprovide the functionality required to set up, manage, and tear down calls and connections;be scalable to support a very large number of registered endpoints (in the order of billions worldwide), and a very large number of simultaneous calls (in the order of millions worldwide);support network management features for policy control, accounting, billing, etc;provide a mechanism to communicate and set up the Quality of Service requested by the end points;be extensible to help with adding new features easily;support interoperability among different vendors implementations, among different versions of the signaling protocol, and with different signaling protocols.

  • Multimedia Protocol Stack

  • Registration Process

  • SIP COMPONENTS AND MESSAGESInvite: Indicates that the user or service is being invited to participate in a session. Ack: Confirms the client has received a final response to an Invite request.Options: Is used to query a server about its capabilities. Bye: Is sent by a User Agent Client to indicate to the server that it wished to release the call. Cancel: Is used to cancel a pending request. Register: Is used by a client to register an address with a SIP server

  • SIP COMPONENTS AND MESSAGES1xx: Informational- The request has been received and processing is continuing. 2xx: Success An Ack, which indicated that the action was successfully received, understood, and accepted. 3xx: Redirection Further action is required to process this request.4xx: Client Error The request contains bad syntax and cannot be fulfill at this server. 5xx: Server Error The server failed (for internal reasons) to fulfill an apparently valid request. 6xx: Global Failure The request cannot be fulfilled at any server.
