Ingate is the leader in SIP capable firewalls. SIP (Session Initiation Protocol) is the standard protocol used by providers of real time communications, especiall VoIP. The SIP standard is becoming for person-to-person IP communications what HTTP is for the Web.
The problem? Existing enterprise firewalls prevent the traversal of SIP-based communications. Existing firewalls do not allow unsolicited incoming calls while media stream in VoIP calls also present problems for NAT traversals.
Ingate’s SIP-capable firewalls and SIParators create a bridge between enterprise networks and the latest in Internet communications. Ingate brings SIP to the enterprise.
The Ingate Firewall® combines stateful inspection and packet filtering with a SIP proxy and registrar to dynamically manage the firewall ports for safe delivery of realtime media streams. The SIParator® allows enterprises to utilize SIP communications without replacing the existing firewall.
