SIP Trunking – connecting business PBXs to operator’s SIP based telephony infrastructure via IP instead of TDM lines – has opened up new market segments and new business opportunities for telecom operators. The shift to IP-PBXs at the customer sites and to IP based infrastructure at the carrier side, is making SIP Trunking an obvious development. Today, almost every ISP, broadband provider or telco in general are planning to offer or are already offering SIP Trunking services. However, getting business customers’ telephony traffic isn’t just about having a good service and rolling it out over a good IP pipe (dedicated/managed or over the Internet) – one also has to be able to connect the service to the customer’s PBX in the customer’s environment. Having a SIP Trunking interface on an IP-PBX is not sufficient! Most obvious is the firewall/NAT traversal problem. Modern IP phones and IP-PBXs reside on the business LAN that is protected by a firewall. But SIP communication does not pass ordinary firewalls or even NATs. A NAT/firewall traversal method is required, which is one of the functions the IX78 E-SBC provides. The IX78 E-SBC has both an Ethernet and an ADSL WAN interface. In addition, there are many variants of the SIP capabilities and implementations in PBXs as well as the trunking service and delivery, something that the IX78 E-SBC can normalize. The picture below shows the functions and benefits the IX78 E-SBC brings when SIP Trunking various types of PBXs.

Intertex’s sister company Ingateis well known in the SIP Trunkingmarket. While the Ingate productsaddress larger installations, Intertex products are focused on the SOHO and SBE higher volume market segment. Both companies cooperate closely and share the SIP development and interoperability testing against the various PBXs, and can therefore offer the most comprehensive interoperability listing.
Below is a screenshot from theinstallation wizard we have created for Swedish incumbent telco Telia, for their “Telia SIP-anslutning” service (8 simultaneous calls).
Every installation is done with an IX78 E-SBC and the service is either delivered over ADSL 2+ Annex M with a quality assured PVC for the voice, or on their managed business Internet service with Ethernet termination. The IX78 E-SBC handles both the voice and data traffi c (with QoS), or optionally, only the voice traffi c.
The Intertex IX78 E-SBC offerssolutions for all types of SIPtrunking services and IP-PBXs (and
conventional PBXs with an addedIP/SIP interface). It has a capacityfor 50 simultaneous calls over thetrunk.
Without an Intertex type of CPE, aSIP Trunking service will only reacha limited portion of the market;only a few types of PBXs can beconnected, or a connection mayrequire that the customer have to (re)install his local IP-PBX telephony in a way that inhibits unifi ed communication and other expected functions and features of his telephony system.
With the Intertex IX78 E-SBCdeployed as part of the SIPTrunking service, your service will be able to connect all types of PBXs with SIP Trunking interface.
The IX78 E-SBC lets the customer’s IP-PBX remain connected to the LAN and the customer can use both phones and PC clients as well as WLAN connected mobile phones as part of their telephony solution.
Remote users (e.g. home workers and road warriors) using SIP clients can also connect to the PBX over the Internet.
