SIP


Increase Your Collaborative Capabilities at a Low Cost

Not being able to support a high volume of calls between multiple office locations can restrict collaborative efforts among your company. Many companies are looking for a way to put simultaneous calls onto their T1 (or other access method), to direct incoming calls to various locations or to have local phone numbers from their nationwide sites all ring in a central location.

Session Initiated Protocol (SIP), is a type of VoIP protocol that utilizes an IP connection to pass voice traffic from one device to another. Since SIP is a different language (than traditional voice transmission), your company’s phone system must be SIP-compatible in order to utilize this technology.

  • Maximize Flexibility and Capacity. Using SIP trunks allows you to run voice, video and data traffic over the same IP network connection. That enables you to consolidate WAN and LAN connections and make the most of the bandwidth you are buying.
  • Reduce Communication Costs. Save an average of 33 percent a year on telecom costs. By moving to an SIP, you can reduce long distance costs through least-cost routing.
  • Enable Collaboration Services. SIP is an enabler of collaboration services by extending voice and video between your organization and the service provider’s network.
  • Buy fewer circuits. If you choose to use compression, SIP voice calls will take less bandwidth per call than traditional methods, allowing you to put as many as 48 simultaneous calls on a single 1.54M T1 (which traditionally could only hold 23 using a PRI T1).  Eliminate many of the separate analog and TDM trunks that are servicing your company’s headquarters and branch offices.
