The concept of getting voice and video calls over the internet is enabled by the SIP or the Session Initiation Protocol standard. It involves IP call and call control as well as the destruction of calls. Some of the features that can be facilitated with the help of SIP in the mobile VoIP world include:
Use of Public telephone system: SIP trunking
Transfer calls, hold, and presence status
The compatibility to the CRM and unified communication systems
SIP provides business and user flexibility, cost savings and a feature update via the air easily.
5G networks introduction is a game changer to SIP based mobile voice:
Allows natural conversations by use of ultra low latency (<10 ms)
Its high definition audio and video are run using massive bandwidth (up to 10 Gbps)
Network slicing will ensure voice calls are made despite high traffic in data calls
With Edge computing, the SIP call control is processed in proximity to the user so that it can respond instantly
The combination of 5G and SIP can unleash next generation mobile voice services which would be impossible with 4G or Wi Fi only.
3. Primetime Advantages of 5G Powered SIP Mobile Voice
Clarinet Quality Sound
The wide channels and codecs that 5G provides transmission of HD and even ultra HD voices.
Zero Perceptible Latency

Make sure that smartphones and softphones are SIP over 5G and required codecs-enabled (e.g., Opus).
Carrier Support
Collaborate with mobile carriers that sell custom 5G tracks or specific VoNR (Voice over New Radio).
Security Policies
Require SIP TLS/SRTP cipher and locked confirmation (SIP digest or certificate based).
Quality Monitoring
Use real time QoS dashboards to monitor 5G SIP latency, jitter and packet loss.
