V1 VoIP SIP Termination Least Cost Routing

V1 VoIP defines SIP Trunking termination session initiation protocol for VoIP

In order to assure call accuracy, V1 VoIP analyzes several aspects of the client’s needs such as typical calling area, average call duration (ACD), calls per second (CPS), and average success ratio (ASR) – to determine the best group of upstream carriers to utilize for the client’s route path. These factors are usually based on a sample call detail record (CDR) supplied by the SIP Termination client. Because of this, V1 VoIP is proud to offer lease cost routing (LCR) services.

With V1 VoIP LCR services, we are able terminate calls to a vast group of upstream carriers. Depending on a SIP Termination client’s traffic profile, V1 VoIP creates a custom route path for each client. That route path typically includes several upstream carriers to deliver the client’s traffic.

Once a route path is constructed for the client, the client is given a ratedeck informing them of the cost to deliver calls based on OCN / LATA. Embedded in V1 VoIP’s infrastructure is a proprietary LCR engine that selects the cheapest available route for each call the client produces. If the lowest cost carrier is not available to complete the call, we route-advance to the next cheapest upstream carrier.

V1 VoIP’s LCR enables us to give clients an aggressive and low cost ratedeck for SIP Termination. It also allows us to deliver the highest ASR in the sip termination marketplace!

V1 VoIP Explains The Difference between H.323 and SIP

V1 VoIP explains the history of H.323 and SIP protocols, what they are used for and how they are different

SIP is rapidly becoming one of the most popular protocols by V1 VoIP resellers for business and VoIP users a like. But there is another protocol that originated before SIP: H.323. What exactly is H.323 and how does it differ from SIP you ask? Allow us at V1 VoIP to explain the difference.

Most VoIP protocols perform the same function, meaning users can rarely detect a difference. However each design is unique and thus possesses superiorities and/or inferiorities over others. For instance, H.323 uses binary while SIP ASCII.

In 1995 as computer usage become more mainstream, researchers began looking for ways to exchange audio and video data between computers. H.323 came about first, becoming the accepted standard for audio and video communications in 1996. It was not until 1999 that SIP achieved similar commercial success; and by 2002, it became the official protocol, published under the name of RFC 3261.

To complement H.323 and SIP, another class, referred to as device control protocols, emerged before the new millennia. During this time, IT technicians redesigned IP interfaces to include components for both data over the internet and for audio signals on the PSTN. These devices, known as gateways, convert signals from one network into a form compatible with another, thus device control protocols like H.248 and MGCP are incredibly useful for unified communications.

While gateways still exist, H.248 and MGCP are no longer the only device control protocols on the market. H.323/H.248 are almost exclusively deals with long-haul communications—PSTN networks that encompass a large geographical distance. Although SIP now leads the industry, various media and codex protocols now play a role in audio and video communications while
other non-standard protocols have emerged through companies like Cisco, Microsoft and Google.
