Why Choose SIP.US for Asterisk

A phone system includes two high-level components.  First there’s the PBX (private branch exchange), in this case Asterisk, which includes call management and additional features like voicemail, automated attendants, call distribution groups and so forth.  The next component is a connection to the Public Switched Telephone Network (PSTN), which routes calls to their intended recipient.  Traditional phone systems use carrier provided PRI (primary rate interface) lines to connect to the PSTN.  SIP is an alternative that leverages a data network, rather than telephone lines, to deliver calls to the PSTN.

Customers choose to deploy SIP trunking with Asterisk for a variety of reasons including:

  • Most companies recognize a cost savings from deploying SIP.US vs. traditional PRI lines
  • SIP.US offers the flexibility to purchase as few as one channel at a time, giving you the ability to pay for only what you need now and grow at any time
  • With SIP.US customers can choose the Internet bandwidth that is most reliable and inexpensive for them
  • SIP.US offers additional features, including as real-time call data records and Nomatic e911
  • We leverage a Tier-1 redundant network to ensure both quality and reliability
  • SIP.US has been tested for use specifically with the Asterisk platform and is leveraged in Asterisk deployments across the country
