Porta SIP

PortaSIP is a call control software package enabling service providers to

build scalable, reliable VoIP networks. Based on the Session Initiation

Protocol (SIP), PortaSIP provides a full array of call routing capabilities to

maximize performance for both small and large packet voice networks.

PortaSIP allows IP Telephony Service Providers to deliver

communication services at unusually low initial and operating costs that

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 enhances ITSP network

management capabilities.
