P a g e 5PREFACEWelcome to SIP Trunking brought to you by SUNCOM in partnership with AT&T. We’re excited you’ve made thedecision to move your organization onto the forefront of technology by implementing SIP Trunking. SIP Trunking isa very powerful and feature-rich platform upon which your organization will conduct its daily business. We’vedeveloped this Administrator’s Guide to help you through some of the intricacies inherent with the service andhope you find it useful.
P a g e 6PURPOSE OF THIS GUIDEThe SIP Trunking Admin Guide describes the operational handling and support for SIP Trunking Services betweenthe Department of Management Services (DMS) and its users. This guide is the summary of the operations tasksassociated with the SIP Trunking services and operational procedures. This guide describes: Where to go to ask questions or report problemsHow the trouble reporting and resolution process worksHow to establish new or make changes to existing serviceHow your service will be billed
P a g e 7WHAT IS SIP TRUNKING?SIP Trunking is an integrated access, converged solution designed to deliver outbound, inbound, Local and LongDistance calling over the State’s MPLS data network, the MyFloridaNet (MFN). It is deployed in situations wherecustomers own their own premises telephony (analog phones, key system, TDM PBX, or IP PBX) equipment.Hosted solutions such as AT&T’s Hosted Voice Solution (HVS) may also be used in conjunction with SIP Trunking. IPFlexible Reach provides “trunk service” over integrated access.SUNCOM’s SIP Trunking solution provides Local, US Long Distance, International voice and fax calling, delivered viaAT&T’s advanced VoIP infrastructure.AT&T supports the integration of customer’s voice and data applications by leveraging the MyFloridaNet inconjunction with a variety of access choices.AT&Ts SIP Trunking provides many benefits to a customer: Improved Total Cost of Ownership by allowing voice and data on a single access trunkSite-to-site on-net calling at no additional cost or any other inter-company location that is on AT&T’s VoIPinfrastructure.Allows customers to add VoIP to their existing MFN provided data transport (may require an MFN CPEupgrade) resulting in more efficient use of your network bandwidth.Utilizing SIP enables enhanced and value added features associated with voice and data applications.Allows for routing of the VoIP calls efficiently and securely.It is very scalable with little upfront investment.Support different codec’sProvides an excellent option and cost benefit when designing a communications system for disasterrecovery.
P a g e 8PRODUCT OVERVIEWSIP Trunking is an integrated access, network service that provides the elements necessary to voice-enable acustomer’s IP service. Local, US Long Distance and International calling are supported on the MyFloridaNet.SIP Trunking supports voice traffic, originated from the customer’s voice system (e.g. IP-PBX) or the PSTN, that isconverted to data packets, allowing customers to use their MFN connection for data, voice and fax traffic.Customers choose the calling capacity they require in units of Concurrent Calls, which are similar to simultaneouscalls
reliably. This service is available to all MFN customers. The QoS features of the MFN allow your voice traffic to be treated with the correct priority while traversing the MFN. With these two interconnects, SIP trunks can be delivered to an IP-PBX or SBC. Multiple MFN circuits into a location can provide route diverse protection at the access .
