1 VoIP made simple.Welcome to Vertical’sSBX IPTechnical Webinar
2 ObjectiveTo provide Vertical dealers with the necessary tools, information and experience essential to the successful deployment and implementation of the SBX IP 320TopicKSU Configuration for Session Initiation Protocol (SIP) Trunks.
3 Tools You Will Need Laptop Network Diagram Ethernet Cables (Straight-through and Crossover)Ethernet HubWireshark (Free Packet Capture Software)Being Prepared Will Save You Time
4 Requirements Static Public IP Address for the VOIB (cannot be shared) Direct/Routed Internet Access or 1-to-1 NAT Capable DeviceCertified SIP Carrier And Account Information (Certified Carrier Documentation Available On VConnect)VOIBSBX PCAdmin SoftwarePort Forwarding Is NOT Supported For VOIBPAT Is NOT Supported For VOIB44

9 What Is SIPThe Session Initiation Protocol (SIP) is a signaling protocol used for establishing sessions in an IP network. A session could be a simple two-way telephone call or it could be a collaborative multi-media conference session. SIP is developed purely as a mechanism to establish sessions, it does not know about the details of a session, it just initiates, terminates and modifies sessions.Over the last couple of years, the Voice over IP community has adopted SIP as its protocol of choice for signaling. SIP is an RFC standard (RFC 3261) from the Internet Engineering Task Force (IETF), the body responsible for administering and developing the mechanisms that comprise the Internet. SIP is still evolving and being extended as technology matures and SIP products are socialized in the marketplace.
10 SIP MessagesSIP Is A Text-based Protocol. The Client Makes Requests and the Server ReturnsAnswers to Client Requests Using Two Types of Messages. Requests (Methods)And Answers (State Codes).1xx Provisional/Informational Response – Request Received and Processing*A Server sends a 1xx response if it expects to take more than 200 ms to obtain a final response2xx Success – The Action Was Successfully Received Understood Accepted3xx Redirection – Further Action Needs To Be Taken To Complete Request4xx Method/Client Error5xx Server Failure/Error6xx Global Failure/Error
11 SIP MethodsThe Initial Line/Request Line Is Most Important Part of SIP Request. It Containsthe Method Name, Request URI and SIP Protocol Version. There are Six BasicMethods (RFC 254) for Client RequestsINVITE: Invite a User or a Service to a New Session/Modify SessionACK: Confirm Session EstablishmentOPTION: Request Information About the Capabilities of a ServerBYE: End of a SessionCANCEL: Cancel a Pending RequestREGISTER: Register the User Agent
12 SIP Call SetupWe go off-hook and dial a number. Authentication/registration with the CarrierOccurs and is accepted.Call is processed by carrier and returns ring to us.Call is answered and connected.Conversation takes place.We end the call and it is disconnected andthe line cleared.
13 SIP Error Messages4xx Method Failures/Client Error - Generally Authentication Failure401 Unauthorized - Authentication Failure402 Payment Required - Call Rejected403 Forbidden - Authentication Failure5xx Server Failure/Server Errors - Server Failed to fulfill a Valid Request503 Service Unavailable - SIP Server May Be Down504 Gateway Timeout - SIP Server May Be Down6xx Global Failure/Global Errors – Request Cannot Be Fulfilled at Any Server600 Busy Everywhere - User Busy606 Does Not Exist Anywhere - Unallocated Number*Many 4xx Errors Report On The Station Display
