This is a short list of projects we are actively involved with.
Blink is a state of the art, easy to use SIP desktop client for Mac, Windows and Linux. Blink offers Rich Multimedia Communications based on SIP protocol using Future Proof Addressing in the form of an e-mail address. Easy integration with existing SIP Service Providers. Open Source, you get the source code and you can contribute.
Sylk Pushserver was designed to act as a central dispatcher for mobile push notifications inside RTC provider infrastructures. Both the provider and the mobile application customer, in the case of a shared infrastructure, can easily audit problems related to the processing of mobile push notifications.
SylkServer allows creation and delivery of rich multimedia applications accessed by SIP Clients, XMPP endpoints and WebRTC applications. The server supports SIP and XMPP signaling, RTP, MSRP and WebRTC media planes, has built in capabilities for creating multiparty conferences with wideband Audio, IM/ File Transfers and can be easily extended with other custom applications by using Python language.

SIP SIMPLE client SDK is a Software Development Kit for easy development of SIP multimedia end-points with features beyond VoIP like Session based Instant Messaging, File Transfers, Desktop Sharing and Presence. Other media types can be easily added by using an extensible high-level API.
SIP Thor is a Peer-to-Peer overlay that allows for load balancing, self-organization and geographical distribution of SIP infrastructure elements. SIP Thor allows for distribution of hardware resources in multiple datacenters and in different geographical locations. Using SIP Thor all relevant computing resources can be virtualized allowing for running the SIP services "in the cloud" with a high scalability/cost ratio. The infrastructure can scale deterministically to handle millions of end-points.
OpenSIPS (Open SIP Server) is a mature Open Source implementation of a SIP server. OpenSIPS includes application-level functionalities. With a very flexible and customizable routing engine, OpenSIPS 'unifies voice, video, IM and presence services in a highly efficient way, thanks to its scalable (modular) design.
OpenXCAP is an Open Source, easy extensible, fully featured XCAP server with TLS security and support for multiple realms. XCAP protocol allows a client to read, write, and modify application configuration data stored in XML format on a server.
MediaProxy is a media relay for RTP/RTCP and UDP streams that works in tandem with OpenSIPs to provide NAT traversal capability for media streams from SIP user agents located behind NAT.
CDRTool is an Open Source solution that provides mediation, accounting and tracing for Call Detail Records enerated by OpenSIPS by using RADIUS protocol and OpenSIPS siptrace facility.
The main role of the MSRPRelay is to help NAT traversal of media sessions between endpoints located behind NAT. It can also be used for lawful interception or enterprise policy for IM sessions. This extension is defined in RFC 4976.
NGNPro is a SOAP/XML provisioning server that manages the addition, modification and deletion of entities like customer information, SIP domains, SIP accounts and SIP aliases on OpenSER, voicemail boxes on Asterisk, ENUM ranges and numbers, DNS zones and records on Power DNS server and rating plans on CDRTool rating engine.
Call Control is a prepaid application that can be used together with OpenSIPS and CDRTool rating engine to limit the duration of SIP sessions based on a prepaid balance.
