Description

Kamailio® is an open-source SIP server, which evolved from the earlier OpenSER and SER, and is distributed under GPLv2+, capable of managing thousands of call setups each second. This robust platform can be utilized for constructing extensive systems for VoIP, real-time communication, presence, WebRTC, instant messaging, and various other applications. Additionally, Kamailio is well-suited for scaling SIP-to-PSTN gateways, PBX systems, or media servers such as Asterisk™, FreeSWITCH™, or SEMS with ease. Its extensive feature set includes support for asynchronous TCP, UDP, and SCTP, secure communication through TLS for voice, video, and text, as well as WebSocket compatibility for WebRTC. The server supports both IPv4 and IPv6, offers simple instant messaging and presence capabilities with an integrated XCAP server and MSRP relay, and enables asynchronous operations. Furthermore, it includes IMS extensions for VoLTE, ENUM functionality, DID and least cost routing, load balancing, and routing failover. Kamailio also provides comprehensive accounting, authentication, and authorization features, while supporting a variety of backend systems, including MySQL, Postgres, Oracle, Radius, LDAP, Redis, Cassandra, MongoDB, and Memcached. All these capabilities make Kamailio a versatile choice for modern communication infrastructures.

Description

SessionPBX offers a cloud-based phone system tailored for small teams and service providers. Through an intuitive web portal, administrators can oversee users, extensions, and calling features, while team members benefit from companion softphone applications available on platforms like Windows, macOS, iOS, and Android. This service provides a comprehensive suite of functionalities, including internal calling, voice and video communication, messaging, presence indicators, voicemail capabilities, call forwarding, and SIP trunk connections that customers can select and pay for independently. The Teams Business package enhances the offering by incorporating advanced features such as call flows, business-hours routing, IVR menus, ring groups, call queues, call recording, supervision tools, and detailed reporting. Additionally, the use of QR codes and invitation links streamlines the provisioning process for team applications. While SessionTalk manages the standard service, approved partners also have the opportunity to implement a multi-tenant version of SessionPBX on their own servers and oversee their customers' workspaces, ensuring flexibility and control over the service. This versatility makes SessionPBX an appealing choice for businesses looking to optimize their communication systems.
