SIP OverviewSIP Overview

• Session Initiation Protocol (SIP)– Internet Engineering Task Force (IETF) standard for multimedia

conferencing over IP• SIP is an ASCII-based, application-layer control protocol (defined in

RFC 3261) that can be used to establish, maintain, and terminate calls between two or more end points

• SIP provides the capabilities to:– Determine the location of the target end point– Determine the media capabilities of the target end point—via Session

Description Protocol (SDP)– Determine the availability of the target end point– Establish a session between the originating and target end point– Handle transfer and termination of calls

• BroadWorks Application Server acts as a back-to-back user agent– Terminates the incoming call-half, applies services and if necessary,

originates an outgoing call-half

Slide 17


• SIP (Methods) Requests– INVITE—Indicates a user or service is being invited to participate in

a call session– ACK—Confirms that the client has received a final response to an

INVITE request– BYE—Terminates a call and can be sent by either the caller or the

callee– CANCEL—Cancels any pending searches but does not terminate a

call that has already been accepted– OPTIONS—Queries the capabilities of servers– PRACK – Provisional acknowledgement– REGISTER—Registers the address listed in the To header field with

a SIP server

Slide 18

SIP OverviewSIP Overview• Types of responses used in response to a Request

– SIP 1xx—Informational Responses (for example, 180 Ringing)– SIP 2xx—Successful Responses (for example, 200 OK)– SIP 3xx—Redirection Responses (for example, 302 Temporarily Moved)– SIP 4xx—Client Failure Responses (for example, 404 User Not Found)– SIP 5xx—Server Failure Responses – SIP 6xx—Global Failure Responses– Registration Process– Registration occurs when a SIP client must inform the Application Sever of

its location– During this process, the client sends a REGISTER request to the

Application Server and includes the address (or addresses) at which it can be reached

– Registrations can require Authentication (shared-secret)

Slide 19


• Invitation Process– An invitation occurs when one SIP end point (user A) "invites"

another SIP endpoint (user B) to join in a call– User A sends an INVITE message to the Application Server

requesting that user B join or set up a call– Application Server processes the request and returns an

appropriate response (for example, 100 Trying, 487 User Busy)– If necessary, the Application Server initiates a terminating call-

half to user B and mediates the two call-halves – If user A no longer wants to end the call, it sends a BYE

message

MGCP OverviewMGCP Overview

• Media Gateway Control Protocol (MGCP) – Internet Engineering Task Force (IETF) standard for multimedia

conferencing over IP• MGCP is an ASCII-based, application-layer control protocol (defined in

RFC 2705) that can be used to establish, maintain, and terminate calls between two or more endpoints

• MGCP is a client-server protocol. The Call Agent (server) handles all aspects of setting up calls to and from endpoints

• MGCP provides the capabilities to:– Determine the location of the target end point– Determine the media capabilities of the target end point—via Session

Description Protocol (SDP)– Determine the availability of the target end point– Establish a session between the originating and target end point

• BroadWorks Application Server acts as an MGCP Call Agent (CA)

Slide 23


• MGCP messages composed from short list of primitives• NotificationRequest (RQNT)—Instructs the MGCP device to watch for

specific events• Notify (NTFY)—Informs the CA when requested events occur• CreateConnection (CRCX)—Creates a connection to an endpoint • ModifyConnection (MDCX)—Changes the parameters associated with

an established connection• DeleteConnection—Deletes an existing connection. ACK returns call

statistics• AuditEnpoint (AUEP)—Audits an existing endpoint• AuditConnection (AUCX)—Audits an existing connection• RestartInProgress (RSIP)—Is a gateway notification to the CA that an

MG or an endpoint is restarting or stopping

Slide 24


• Notification Messages– MGCP device uses these messages to tell the CA of a change of

state– Typically involve signaling or events– Examples:

• Signals: Ringing, distinctive ringing, ring back tone, dial tone, intercept tone, network congestion tone, busy tone, confirm tone, answer tone, call waiting tone, off-hook warning tone, pre-emption tone, continuity tone, continuity test, DTMF tones

• Events: On-hook transition, off-hook transition, flash hook, receipt of DTMF digits

How to ConnectHow to Connect

• Customer must have XL MPLS connection• Additional setting will be added by XL in CE (Customer Edge)

MPLS Router will ALG (Access Layer Gateway) setting.• After ALG has been set up, the AES will recognize the IP

Address Gateway and designated Port for every subscriber. • XL will create SIP subscriber remotely (in AES) based on

customer gateway. (subscriber hierarchy in the next slide)• SIP CPE (Customer Premise Equipment) will be set up by

customer. The setting will be:– Set IP Address– Set SIP Proxy– Set User ID and Password
