WEBINAR VoLTE An in depth analysis

Overview:
VoLTE, a fundamental component of modern telecommunications, enabling the transmission of voice calls as data packets across LTE networks. However, it faces significant security challenges due to historical oversights and rapid technological advancements. While security controls like SIP proxies are implemented, there are still critical aspects from mobile operators’ perspectives that may be overlooked. Our VoLTE study has unearthed these issues.
In this webinar based on our latest research paper on VoLTE security we have covered
