VoLTE IMS call flow with Yate Core Network
VoLTE IMS registration and VoLTE call flow can be seen both in YateUCN equipment and in Wireshark.
This video is a desktop recording of a MiniCore during a VoLTE call.
Captures are also available on https://wiki.yatebts.com/captures/LTE...
In the first part of the video you can see the interaction of the elements in the Core Network during a 4G call, a VoLTE call and a 4G SMS, an SMS over SIP. This video shows you what sees an admin sees in the equipment, the IMS call + SMS IMS in YateUCN and later on you can see how it looks in Wireshark.
This is our YateUCN console and here you can SIP activity during a VoLTE call and SMS over SIP. First SIM is trying to register, we see how the authentication and registration are made for the first MSISDN with number 8822041.
The second number registers to the Network and a VoLTE call is starting (the full call flow can be seen in the captures). Here you can see both phone numbers registered to 4G (data, APN: internet) and IMS (voice, APN: IMS) and how a phone call over LTE is made.
An SMS is sent via SIP over a 4G connection and we can see how it looks in YateUCN console.
These are captures where you can see every message in the Core Network and the internet or IMS traffic. Wireshark can open captures with both VoLTE call and SMS over IP.
Thanks for watching VoLTE IMS call flow with Yate Core Network
