IPLOOK's Virtualized IMS Enable voice services on any 4G, 5G and other data-only networks
- IPLOOK’s IMS system is 100% compliant (3GPP) and SIP-based. The product meets the VoLTE/VoNR service function of the operator’s LTE/5G network and can also cooperate with the dedicated EPC as a multimedia service function under the dedicated network.
- Our fully virtualized IMS solution is based on lightweight containers (Docker Swarm, Kubernetes) and runs on any public or private cloud (e.g. Oracle, Amazon, RedHat, etc.) as well as on hardware.
- Our IMS solution has been integrated with the hardware and software of all industry suppliers. This provides the highest possible flexibility to integrate with both industry structure and innovative (open-source) applications.

Scale to millions of subscribers per service
Enable the use of HD voice and EVS voice codecs, including transcoding, delivering a better quality of experience (QoE) for end-users compared to over-the-top (OTT) services
Provides SIP signaling control and media anchoring to ensure voice call continuity for calls that traverse LTE and 3G networks
Secures the network edge for user access and/or peer network interconnection with topology hiding, Internet Protocol Security encryption (IPSec), Transport Layer Security (TLS), Secure Real-Time Transport Protocol (SRTP) and intrusion protection such as from Distributed Denial of Service (DDoS) attack
FAQ
What is IMS and why is it important for modern telecom networks?
IP Multimedia Subsystem (IMS) is a cloud-based communication framework that enables real-time multimedia services such as VoLTE, VoNR, Wi-Fi calling, voice, video, messaging, and conferencing across 4G, 5G, and other IP networks. IMS plays a critical role in delivering carrier-grade voice services and seamless communication experiences in next-generation networks.
What voice services does IPLOOK’s IMS support?
IPLOOK’s IMS supports VoLTE (Voice over LTE), VoNR (Voice over NR), Wi-Fi Calling, HD Voice, EVS codecs, SMS over IMS, conferencing, and multimedia communication services. It also supports seamless voice continuity between 4G, 5G, and legacy 2G/3G networks through SR-VCC functionality.
Is the IMS solution cloud-native and virtualized?
Yes. IPLOOK’s IMS is fully virtualized and cloud-native, supporting deployment on Docker Swarm, Kubernetes, public clouds, private clouds, and COTS hardware. This enables operators to scale services flexibly, simplify operations, and accelerate service deployment.
How does IPLOOK’s IMS improve service reliability and quality?
The solution provides carrier-grade reliability, SIP-based multimedia processing, media anchoring, and advanced QoS capabilities. Support for HD Voice and EVS codecs delivers higher voice quality compared to traditional OTT communication services, improving end-user experience.
Can the IMS platform integrate with existing telecom infrastructure?
Yes. IPLOOK’s IMS is fully compliant with 3GPP R14 standards and interoperates with hardware and software from major industry vendors. It supports standard interfaces such as Cx/Dx, Rx, Sh, ISC, Ro/Rf, and ENUM, enabling seamless integration into existing LTE, 5G, and fixed network environments.
How does the solution support mobility and roaming?
The IMS platform enables seamless roaming and voice continuity through features such as SR-VCC, SIP signaling control, and media anchoring. This allows uninterrupted voice sessions when users move between LTE, 5G, and legacy 2G/3G networks.
What security features are included in IPLOOK’s IMS?
The solution secures network interconnections and user access with IPSec, TLS, SRTP encryption, topology hiding, SBC protection, and DDoS mitigation capabilities. These features help operators protect voice services and maintain secure multimedia communications.
Which deployment scenarios are best suited for IPLOOK’s IMS solution?
IPLOOK’s IMS is suitable for mobile operators, MVNOs, private LTE/5G networks, enterprise communication systems, fixed-mobile convergence deployments, and telecom service providers looking to enable voice and multimedia services on data-only 4G and 5G networks.
