SIP Profile SIP Server Media Profile Media Lists Contact Registrant Tables Remote Authorization Tables Signaling Group Transformation Call Routing Table SIP Profile Select Settings > SIP > SIP Profiles SIP Profiles control how the Sonus SBC Edge communicates with SIP devices. These control important characteristics such as: session timers, SIP Header customization, SIP timers, MIME payloads, and option tags. The default SIP profile used for the SBC Edge for this testing effort is shown below. Copyright 2016 Sonus Networks. All rights reserved. Page 13

SIP Server Select Settings > SIP > SIP Server Tables SIP Server Tables contain information about the SIP devices connected to the Sonus SBC Edge. The entries in the tables provide information about the IP addresses, ports, and protocols used to communicate with each SIP server. The entries also contain links to counters that are useful for troubleshooting. Copyright 2016 Sonus Networks. All rights reserved. Page 14

Media Profile Select Settings > Media > Media Profiles Media Profiles specify the individual voice and fax compression codecs and their associated settings for inclusion into a Media List. Different codecs provide varying levels of compression, allowing the reduction of bandwidth requirements at the expense of voice quality. Listed below are the media profiles of the voice codecs used for the SBC Edge in this testing effort and is for reference only. Copyright 2016 Sonus Networks. All rights reserved. Page 15

* SFB uses default Media List Media List Select Settings > Media > Media List The Media List shows the selected voice and fax compression codecs and their associated settings. Contact Registrant Tables Select Settings > SIP > Contact Registrant Tables Contact Registrant Tables are used to manage contacts that are registered to a SIP server. The SIP Server Configuration can specify a Contact Registrant Table, and the username portion of the table will be used for outbound calls. Copyright 2016 Sonus Networks. All rights reserved. Page 16

Remote Authorization Tables Select Settings > SIP > Remote Authorization Tables Remote Authorization Tables and their entries contain information used to respond to request message challenges by an upstream server. The Remote Authorization tables defined in this page appear as options in the Remote Authorization and Contacts Panel for SIP Servers. Signaling Groups Select Settings > Signaling Groups Signaling Groups allow telephony channels to be grouped together for the purposes of routing and shared configuration. These groups are the entity to which calls are routed, as well as the location from which Call Routes are selected. These are also the location from which Tone Tables and Action Sets are selected. In the case of SIP, this will specify protocol settings and link to server, media and mapping tables. Copyright 2016 Sonus Networks. All rights reserved. Page 17

Transformation Select Settings > Transformation Transformation Tables facilitate the conversion of names, numbers and other fields when routing a call. For example, transformations can convert a public PSTN number into a private extension number, or into a SIP address (URI). Every entry in a Call Routing Table requires a Transformation Table, and are sequentially selected from there. In addition, Transformation tables will be configurable as a reusable pool that Action Sets can reference. Copyright 2016 Sonus Networks. All rights reserved. Page 19

Call Routing Table Select Settings > Call Routing Table Call Routing allows calls to be carried between signaling groups, thus allowing calls to be carried between ports, and between protocols (like ISDN to SIP). Routes are defined by Call Routing Tables, which allow for flexible Copyright 2016 Sonus Networks. All rights reserved. Page 20

configuration of which calls will be carried, and also how the calls are translated. These tables are one of the central connection points of the system, linking Transformation Tables, Message translations, Cause Code Reroutes, Media Lists and the three types of Signaling Groups (ISDN, SIP and CAS).
