Protocols SIP (Session Initiation Protocol)
Tool Wireshark,
Project Detail Telephony Application Server (TAS) is a scalable carrier-grade Multimedia
Telephony Application Server providing voice and video services to IMS/SIP
clients over any IMS-enabled access type, e.g. LTE, Wi-Fi, etc. It supports
Mobile VoIP (Voice over Wi-Fi) and Voice over LTE (VoLTE) as well as Mobile
Video Calling.
The IMS TAS is uniquely equipped to offer service parity, enabling a
consistent service offering to the user regardless of the access type and
service network. At the same time, the TAS offers a rich suite of new services
and capabilities to IP clients.

References RFC (3261)
Project Detail The Session Initiation Protocol (SIP) is a signaling protocol for
initiating, managing and terminating voice and video sessions across
packet networks. These sessions include Internet multimedia
conferences, Internet telephone calls and multimedia distribution.
Members in a session can communicate via multicast or via a mesh of
uncast relations, or a combination of these.
The protocol can be compressed by using Signaling Compression. SIP
invitations used to create sessions carry session descriptions which
allow participants to agree on a set of compatible media types. SIP
supports user mobility by proxying and redirecting requests to the
user's current location. Users can register their current location. SIP is
not tied to any particular conference control protocol. SIP is designed
to be independent of the lower-layer transport protocol and can be
extended with additional capabilities.
