Kamailio (formerly OpenSER) is a high-performance SIP (RFC3261) server with a flexible architecture and many extensions. The server implements proxy, registrar, redirect, and location SIP/VoIP services. It has support for UDP, TCP, TLS, and SCTP transport layers, DNSsec, ENUM, AAA via database, RADIUS, DIAMETER, gateways to SMS and XMPP, least cost routing, load balancing, NAT traversal, and call processing language. Kamailio implements SIMPLE presence and instant messaging extensions, and includes an embedded XCAP server and MSRP relay. It can be also used as a routing SIP sever for WebRTC via WebSocket.
Ip phone Scanning Made Easy (ISME) scans a VOIP environment, adapts to enterprise VOIP, and exploits the possibilities of being connected directly to an IP Phone VLAN. It seeks to get the phone's configuration file directly from a TFTP server, enable SIP/SIPS (TCP/UDP), communicate with an embedded Web server and Web server banner, identify the editor by MAC address, and identify potential default login/password combinations which should be changed.
WombatDialer is a platform to provide mass outbound calling. This can be used to implement many different services. By offering a set of ready-to-use components and a monitoring GUI, it lets you create complex solution in minutes. It can work on predefined call lists or can dynamically create them over an API (e.g., dial number X after 10:30AM). It shares the load on one or more PBX servers and has flexible rescheduling logic to handle missed calls. It is built to be used with your existing Asterisk PBX, and does not require separate servers or a separate set of lines. It can call over VoIP or through the public telephone network. It is built to integrate with your business processes, and can receive calls to be made over HTTP and/or notify an external system in realtime of calls made and results gathered. It works natively with the QueueMetrics Call-Center Monitoring Suite to produce state-of-the-art campaign analyses and insight.
ScopServ-VoIP is a Web-based management interface (GUI) for the Asterisk system which can be accessed by any XHTML 1.0+ browser. It supports a lot of features like: multiple languages, multiple users, reporting tools, personal IVR, and an end user UI. It is available in SOHO, SMB, Professional, and ITSP editions.
chan-sccp-b is an extension of the original chan-sccp implementation for the Asterisk soft-PBX. It lets you hook up a Cisco/SCCP Phone to your Asterisk server using the SCCP protocol, which works a lot better than the SIP firmware on the same phone. It provides full phone functionality instead of just a simple SIP channel provider. It offers functionality like shared lines, hotline functionality, guest login, dynamic speeddials, private line automatic ring-down (PLAR), personal softkey configurations, Dundi support, SCCP extended dialplan functions, manager support, and custom device state buttons.
