1 VoIP made simple. Welcome to Vertical’s SBX IP Technical Webinar

2 Objective To provide Vertical dealers with the necessary tools, information and experience essential to the successful deployment and implementation of the SBX IP 320 Topic KSU Configuration for Session Initiation Protocol (SIP) Trunks.

3 Tools You Will Need Laptop Network Diagram
Ethernet Cables (Straight-through and Crossover) Ethernet Hub Wireshark (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 Device Certified SIP Carrier And Account Information (Certified Carrier Documentation Available On VConnect) VOIB SBX PCAdmin Software Port Forwarding Is NOT Supported For VOIB PAT Is NOT Supported For VOIB 4 4

5 Static IP Addresses are manually assigned and do not change.
IP Address Matrix Address Class 1st Decimal Range Network/Host ID** Default Subnet Mask A * N.H.H.H or /8 B N.N.H.H or /16 C N.N.N.H or /24 D Multicast E Experimental ** N = Network ID H = Host ID Private IP Addresses: Class A Class B – Class C – * is reserved for loopback diagnostic functions is a “special case” available for use as a broadcast address. Static IP Addresses are manually assigned and do not change. Dynamic IP Addresses are assigned via DHCP and may change from day to day. 5 5

9 What Is SIP The 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 Messages SIP Is A Text-based Protocol. The Client Makes Requests and the Server Returns Answers 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 response 2xx Success – The Action Was Successfully Received Understood Accepted 3xx Redirection – Further Action Needs To Be Taken To Complete Request 4xx Method/Client Error 5xx Server Failure/Error 6xx Global Failure/Error

11 SIP Methods The Initial Line/Request Line Is Most Important Part of SIP Request. It Contains the Method Name, Request URI and SIP Protocol Version. There are Six Basic Methods (RFC 254) for Client Requests INVITE: Invite a User or a Service to a New Session/Modify Session ACK: Confirm Session Establishment OPTION: Request Information About the Capabilities of a Server BYE: End of a Session CANCEL: Cancel a Pending Request REGISTER: Register the User Agent

12 SIP Call Setup We go off-hook and dial a number. Authentication/registration with the Carrier Occurs 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 and the line cleared.

13 SIP Error Messages 4xx Method Failures/Client Error - Generally Authentication Failure 401 Unauthorized - Authentication Failure 402 Payment Required - Call Rejected 403 Forbidden - Authentication Failure 5xx Server Failure/Server Errors - Server Failed to fulfill a Valid Request 503 Service Unavailable - SIP Server May Be Down 504 Gateway Timeout - SIP Server May Be Down 6xx Global Failure/Global Errors – Request Cannot Be Fulfilled at Any Server 600 Busy Everywhere - User Busy 606 Does Not Exist Anywhere - Unallocated Number *Many 4xx Errors Report On The Station Display

14 SIP Call Trace Capture – Failed Call
[SIP-CMD] INVITE sip: ;user=phone From:<sip: > To:<sip: ;user=phone> Contact:sip: :5060 C>10 04, D5 B5 09 1D 3C A E E E E 0A “”Truncated”” [SIP-EVT] SIP_CALLFAIL_RESP_MSG IE_SIP_RESPONSE_CODE:403 IE_SIP_CONTACT:sip: :5060
