PRODUCT SPOTLIGHT: Intertex IX78
Tuesday, April 21, 2009
Asterisk SBC: Intertex' new IX78 E-SBC is an ADSL Modem/Router/Firewall with built in Enterprise Session Border Controller (E-SBC) functionality for SIP Trunking.
SIP Trunking is connecting a company PBX to a carrier's IP SIP telephony service instead of via TDM lines, such as PRI, BRI or multiple analog lines. The IX78 E-SBC now allows service providers to mass deploy high quality SIP Trunks cost effectively over ADSL or Ethernet access, solving the SIP NAT Traversal problem, PBX interoperability with the SIP Service,Security and QoS (Quality of Service).
With the IX78 E-SBC, a service provider can roll out a SIP Trunking service over ADSL, where VoIP is delivered over a quality assured PVC and the unused bandwidth is fully used for non-prioritized Internet traffic over another PVC on the same line. The IX78 E-SBC can alternatively be used with Ethernet access -- VLAN tagged or not -- and also prioritize and traffic shape over a single Internet pipe.
The general SIP functionally and handling of multiple high capacity WAN connections with different priority, is inherited from the triple play,any port, any service IX78 broadband product. In the SIP Trunking case,the IX78 E-SBC creates a unified VoIP and data LAN, where the company gets global SIP connectivity both for the PBX and its phones and for other SIP services, e.g. remote SIP users (home workers and road warriors) connected to the PBX over the Internet.
The capacity is high -- over an ADSL2+ Annex M line, more than 30simultaneous calls can be supported, replacing a full TDM PRI line. For larger installations, Intertex' sister company Ingate Systems, with which it shares an unequalled interoperability listing between PBXs and SIP Trunking service providers, can provide higher capacity E-SBC products.
