ILECs Slowly Embrace SIP

David ByrdRecently, I have noted more information on the Web from the ILECs regarding SIP and SIP Trunking. I remember doing a blog a few years back about how SIP was seldom mentioned and very difficult to get from an ILEC. I see they are slowly coming around, albeit primarily an offering to larger midsize and enterprise customers.

Of course, dedicated access is required and recommended to provide class of service which Broadvox also supports for larger installations. But the real news is the increase in the number of service providers that now offer SIP Trunks. Features appear to be much the same, so pricing, service and flexibility are the differentiating factors.

One bit of information that was difficult to find was the list of products with which the SIP Trunks were certified. Broadvox interoperability test (IOT) is very easy to find on our website and is updated regularly. It is somewhat vexing that the information is not readily available from other service providers. As more businesses wish to take advantage of SIP Trunks, this information becomes critical to avoid the hassles of installing incompatible products.

Most of the complaints regarding SIP implementations can be resolved with proper IOT and documentation. SIP Trunking is not the answer for every IP communications solution, sometimes simple VoIP will do just fine. SIP is required when the solution involves Unified Communications offerings and multi-location networks. But remember, most of Broadvoxs basic SIP Trunking customers are SMBs that want to enjoy the cost savings and business continuity features SIP provides. Most ILECs are not pursuing that market.
