PortaSIP is a call control software package that enables service providers to build scalable, reliable VoIP networks.
Based on the Session Initiation Protocol, PortaSIP provides a full array of call routing capabilities to maximize performance in both small and large packet voice networks. PortaSIP allows IP telephony service providers to deliver communication services at incredibly low initial and operating costs, which cannot be matched by yesterday’s circuit-switched and narrowband service provider PSTN networks.
In addition to conventional IP telephony services, PortaSIP provides a solution to the NAT traversal problem, and also enhances ITSP network management capabilities.

Overview
The PortaSIP solution provides carriers with an open, SIP-based architecture to support enhanced voice applications such as hosted IP PBX service, unified messaging, conferencing and IP call center, as well as a whole new class of services integrating telephony with the web, e-mail and other communications portals.
With PortaSIP, services that combine elements from telephony and other web applications such as e-mail, messaging, Internet and video streaming can be created easily and in a shorter planning/implementation cycle, allowing increased market responsiveness.
The PortaSIP Solution, consisting of:
- PortaSIP extension for PortaBilling100
- SIP proxy server
- B2BUA
provides a platform for delivering innovative, high-margin services that may be deployed over IP, as well as cable, POTS, Broadband, and ISDN networks.

Typical PortaSIP Network Architecture
PortaSIP supports:
- Any SIP endpoint (network element which can terminate a SIP session)
- Universal numbering plan, PBX extensions and other numbering schemes
- Customer dialing rules and abbreviated dialing
- Clustering of gateways and other servers
PortaSIP API allows third party vendors to access all important features of the system (Message Waiting Indication, Directory, etc.).
The Customer Dialing Rules & Abbreviated Dialing feature works with both SIP and H.323, with adequate support of either a SIP server or Cisco TCL IVR. A PortaBilling customer can set up Dialing Rules as an international prefix, outside prefix, direct number (e.g. 911) or abbreviated dialing for his accounts. More than one dialing rule may be assigned to each account.
The system allows “clustering” of gateways and other servers to “roll over” in case of capacity constraints or failure. This allows several devices to be used in tandem, with one overflowing to the next if the number of calls being handled exceeds the limitations of a current device, or if a device fails.
