3. Registrar Server: This server accepts register requests from SIP shoppers to replace their present location. This ensures that when a name is available in, it may be correctly routed to the system’s most up-to-date IP deal with.

Along with facilitating communication setup by way of SIP signaling, there are different protocols concerned in transporting precise chat, voice, or video media information:

1. RTP (Actual-time Transport Protocol): As soon as a SIP name is established, RTP takes cost of transporting the precise media content material.

Right here, among the extra protocols come into play throughout this course of as properly. As an illustration, SRTP encrypts the packets to make sure their safety, whereas RTP sequences and timestamps them to allow clean reconstruction on the receiving finish.
