Need for a SIP Trunking Standard
SIP is the standard for VoIP communications

• SIP alone does not insure compatibility. As of
  January 2008, SIP is comprised of 49 RFCs and 139
  Internet Drafts. The specific support required
  by an IP PBX and service provider was loosely
  defined as it concerns IP PBX to service provider
  peering.
• SIP only defines base primitives
• A higher-level specification was needed
