BUSINESS CONNECTIVITY SOLUTIONS AUDIOCODES DESIGN GUIDE Multi Service Business Gateways (MSBGs) and Enterprise Session Border Controllers (E-SBCs) are key components in migrating into SIP based services. MSBGs and E-SBCs provide businesses with the connectivity, interoperability, survivability, security and quality assurance required to connect to service providers over the Internet using the SIP protocol for signaling. These products can also handle the call traffic and connectivity of users in remote locations. What can you ask the customer? Do you need to connect between TDM and IP PBXs? Are you planning a deployment of SIP Trunking services? Do you need to connect into multiple SIP Trunking service providers and/or PSTN networks? Would you like to gradually connect into SIP Trunking and at the same time be able to connect directly into the PSTN as a fallback? Are you looking for an efficient and secured way to connect home-based workers into your private network? Would you like to ensure voice survivability for business continuity of your branch offices in case of a WAN failure? Do you have Legacy equipment such Analog & Digital phones and TDM PBXs but still want to enjoy the cost savings of SIP Trunking? Are you aware of what your organization s network need to be secured against when connecting into SIP Trunks or IP Centrex services? Are you looking for a highly scalable solution that will allow you to grow on a need basis without paying in advance for excess capacity? As part of the solution, are you looking for an integrated server for hosting key applications? Are you concerned about interoperability issues between your IP-PBX, UC or Contact Center and your service provider s network? Are you looking for a single demarcation point between the service provider network and the enterprise? A-La-Carte configuration options This document will detail a number of scenarios describing a selection of typical configurations used to support different types and sizes of branch offices or enterprise sites. Naturally, there are many more options and customer requirements that cannot be covered in such a document. AudioCodes products allow for various configurations and scaling options, integrating multiple WAN connectivity options, TDM interfaces, SBC session support and other software features based on the specific requirements of the customer.
