OpenSIPS 3.3 – Messaging in the IMS and UC ecosystems 

SIP is more than voice and video, it is also instant messaging and presence. Even if traditional SIP services are more voice-focused, Instant Messaging (IM) has gained a lot of traction in the context of IP Multimedia Subsystem (IMS) and Unified Communications (UC) in the last years.

OpenSIPS 3.3 introduces several new modules which facilitate the implementation of messaging services in both IMS and UC contexts. Tune in to this presentation for an in-depth view on them, as well as all else new in 3.3!

Artificial Intelligence applications for Contact Center

Nowadays, Artificial Intelligence can use Machine Learning algorithms to provide benefits in the call center space, especially when we can deal with some high-quality Telco Data.

Three main AI applications for contact center will be described, from Conversational AI and Sentiment Analysis, to the Agent Recommendation application with Recurring Neural Networks and Generative Transformer.

Not just benefits, but also some main challenges and case studies will be tackled: dealing with conversations by using machine learning and AI is an opportunity, however proper dialog design and multiple other techniques must be considered to experience good performances.

Kamailio for topology hiding and core SIP network protection

Kamailio is a high capacity SIP packet routing engine offering many functions for detecting and blocking malicious traffic targeting real time communication services. Along side, it can be used to hide the routing path, keeping sensitive details out of the sight of bad actors and untrusted peers, significantly increasing the security of RTC systems deployed on the cloud. This talk present the mechanisms offered by Kamailio to completely hide and protect your farm of SIP application systems (PBXes, PSTN gateways, audio/video conferencing systems or other media servers) deployed in your cloud core network.
