The Business Value of SIP Trunking

The Business Value of SIP Trunking
2
SIP Trunking

• creates a connection from a companys phone
  system to the Internet, replacing the
  conventional public switched telephone network
  (PSTN).
• is delivered by a service provider as an overlay
  service to existing broadband access (DSL, cable,
  T1/E1, Ethernet, etc.) or bundled with its IP
  network.
• works with a SIP-ready PBX or with traditional
  analog systems by adding an integrated access
  device (IAD).

How SIP Trunking Works
3
SIP Trunking Reduces Costs by

• Eliminating dedicated circuits. SIP trunking
  eliminates the need for traditional analog and
  digital trunk facilities and allows
  communications to be routed over existing data
  connections.

• Consolidating PBX needs. SIP enables
  communications across the Internet as easy as the
  corporate LAN, so a multilocation business can
  use one centrally located IP PBX instead of
  installing separate ones at each site.

SIP Trunking Optimizes Assets by

• Aligning with usage needs. SIP trunking allows
  companies to right-size their communications,
  buying only what they need. Plus, businesses can
  purchase call paths in small increments and
  increase as their usage grows.
• Supporting Burstability. Some providers also
  offer "burstable" SIP trunking, which allows a
  business to temporarily use more concurrent call
  paths than provisioned to accommodate bursts of
  traffic due to seasonal calling changes or
  temporary marketing campaigns, as two examples.

SIP Trunking Creates Efficiencies by

• Converges voice and data networks. SIP trunking
  also enables companies to converge local,
  long-distance, toll-free, and voice and data
  traffic for greater efficiencies.
• Dynamically allocates bandwidth. Similarly, it
  also allows for dynamic allocation of bandwidth
  for voice and data services, giving priority to
  the real-time traffic, but not requiring paths to
  be reserved for a specific traffic type.

• Converging voice and data networks. SIP trunking
  enables local, long-distance, toll-free, and
  voice and data traffic over the same connection.
• Dynamically allocating bandwidth. It also allows
  for bandwidth to be used for voice and data
  services without reserving paths for a specific
  traffic type.

SIP Trunking Streamlines Management by

• Centralizing communications management. The
  virtual nature of SIP trunking provides for
  centralization of communications tying remote
  locations to a centralized IP PBX.

• Reducing the need for multiple providers. SIP
  trunking also decreases the need for regional
  service providers often required by nationwide
  multilocation companies.

SIP Trunking Supports Marketing by

• Retaining local numbers. SIP trunking enables
  businesses to retain the telephone numbers for
  offices closing due to MA or downsizing and have
  them ring into headquarters. This allows the
  customer to maintain a local presence but to
  consolidate facilities, staff and gain economies
  of scale.
• Virtual Presence. Similarly, a company can create
  new virtual presences with telephone numbers
  from cities within the U.S. and internationally.

SIP Trunking Adds Value by

• Supporting Business Continuity. SIP can be
  programmed to auto forward to mobile phones or
  alternative DIDs, ensuring that customer calls
  are not dropped or unanswered.

• Enabling Unified Communications. SIP is the
  standard protocol for VoIP, but it was designed
  for all types of real-time communications
• presence
• instant messaging
• application sharing
• white-boarding
• video conferencing
