SIP Register Server
A SIP register server maintains a database of SIP identity-to-IP address (or domain name) mapping. The
register server checks your user name and password when you register.
RTP
When you make a VoIP call using SIP, the RTP (Real time Transport Protocol) is used to handle voice data
transfer. See RFC 1889 for details on RTP.
Pulse Code Modulation
Pulse Code Modulation (PCM) measures analog signal amplitudes at regular time intervals and converts
them into bits.
