General Description

In simple terms, a SIP Trunk is primarily a concurrent call that is routed over Iristel’s IP backbone using VoIP technology. SIP Trunks are used in conjunction with an IP-PBX and are thought of as replacements for traditional PRI’s or analog circuits. Depending on your needs, you can choose between the Inbound Only SIP Trunks or 2-way SIP Trunks (inbound and outbound).

Iristel’s IP Trunking solution will connect a Gateway to your PBX. This gateway will serve as the Iristel demarcation point and will leverage your data connection to simultaneously serve both your data and voice needs. Dial tone to your PBX will now be coming from the Iristel network via Iristel’s Gateway that is connected to the patch panel of your PBX. Businesses that already have IP PBXs will not require the Gateway as these PBXs will already be able to accept Iristel’s SIP Trunks.

If you are running a business, particularly a small or medium-sized business (SMB), you are probably weighing the options of how you can economically and efficiently migrate to the benefits of a VoIP solution while not immediately abandoning the investment you have made in your existing PBX/Key system and handsets. Iristel’s IP Trunking solution will enable you to make that move efficiently and cost effectively.
