  • Definition: Session Initiated Protocol (SIP), is a type of VoIP protocol used to send phone service over a data circuit, such as an Internet connection or MPLS connection. When SIP calls are sent over an Internet connection (bring your own bandwidth/BYOB), there is no control or guarantee of voice quality but when sent over an MPLS connection, the voice quality is in a controlled environment and therefore, the quality is guaranteed by the SIP service provider.
  • Best Fit: Companies looking to put pack more simultaneous calls onto their T1 (or other access method) and/or companies with multiple locations that would like to fail incoming calls to different locations and/or companies with multiple locations, wanting to have local phone numbers from their nationwide sites all ring in a central location.
  • Benefits:
    • Reduced costs. Less phone lines.
    • Increased Redundancy. Have multiple failover routes for incoming calls.
    • Increased call management. Nationwide local phone numbers all ringing at a central phone system/central location.
  • Available Features with Select Providers
    • Nationwide Local Phone Numbers (DID’s)
    • Call compression. G.729 or G.711 Codec allows calls to range from approx. 32k – 95k/call.
    • Multiple Failover Routes both in and out of providers’ network.
