Session Initiation Protocol (SIP) is an Internet standard protocol that allows multiple trunks to be used to replace standard lines on an IP based phone system. VoIP is a technology that allows us to make telephone calls over an IP network (like the Internet) instead of over traditional landlines.

  • Is your current or proposed voice server (PBX) SIP enabled?
  • Do you have multiple locations networked together?
  • Does your current WAN infrastructure have enough bandwidth available to overlay voice traffic?
  • Do you have remote users in disparate regions?
  • Do all of your remotes sites have their own local trunking?
  • How do you handle failover and overflow with your current voice services?


Features & Benefits of SIP

  • Increased control and ease of call routing.
  • Telephone numbers from disparate rate centers can be groomed to a centralized circuit, allowing companies in one city have local number presence in other locales. (Number Portability)
  • Cost savings ability when multiple networked locations can remove local trunking and centralize to a main voice server.
  • Scalability - Allows you to increase call paths as your business demand dictates.
  • Seamless Activation with No Upfront Costs & Active Within Days o Little or No Incremental Infrastructure Investment
  • Support for HD Audio & Video
  • Built In Redundancy with Multi- Provider Failover
  • Geographic Diversity


Top Scenarios where SIP is a good fit

  • Multiple locations, connected by a WAN, with disparate local trunking today. SIP can be used to consolidate the trunking, give workers who travel between locations more flexibility, as well as teleworkers.
  • Smaller client, with an IP enabled voice server and bandwidth, needing redundant dial tone from their existing copper services at a low cost
