Overview

What it does

CallityLabs Network Infrastructure combines AI AS Server and AI MRF Server to deliver SIP-native service control and real-time conversational media intelligence.

Where it is used

Deployed in IMS/SIP cores, telecom voice platforms, and enterprise call automation environments that require low-latency voice AI runtime.

Why it matters

It matters because separation of signaling control and media AI runtime improves reliability, policy governance, and conversational response performance at large scale.

AI MRF / Media Resource Function

Real-time media processing for IMS, SIP, and Voice AI

What is an MRF (Media Resource Function)?

An MRF is the media-processing layer in an IMS or SIP architecture. It terminates and anchors RTP sessions and performs functions such as codec processing, transcoding, media mixing, announcements, tone detection, conferencing, recording, and IVR media execution.

What makes an AI MRF different?

An AI MRF extends the traditional Media Resource Function with streaming speech recognition, text-to-speech, conversational AI connectivity, real-time media events, and low-latency voice pipelines while retaining telecom-grade session and media control.

FAQ

AI MRF and Media Resource Function FAQ

What does MRF mean in telecom?

MRF means Media Resource Function. It provides real-time media processing for IMS and SIP services, including RTP handling, codecs, mixing, conferencing, announcements, recording, and IVR.

What is an AI MRF?

An AI MRF combines traditional telecom media processing with streaming STT, TTS, conversational AI, and real-time voice intelligence in the live media path.

How does an AI MRF connect to IMS?

The AI MRF processes RTP media while an application or control server coordinates SIP signaling, session policy, routing, and service logic with the IMS or SIP core.
