Traditionally, voice and data were carried over separate networks optimized to suit the differing characteristics of voice and data traffic. With advances in technology, it is now possible to carry voice and data over the same networks whilst still catering for the different characteristics required by voice and data.

DAP is actually a simple protocol that is used to access directory services. It is an open, vendor neutral information such as e-mail addresses and public keys for secure transmission of data. The information contained within an LDAP directory could be ASCII text files, JPEG photographs or sound files. One way to reduce the time taken to search for information is to replicate the directory information over different platforms so that the process of locating a specific data is streamlined and more resilient to failure of connections and computer ....etc

Session Initiation Protocol (SIP) is a protocol developed by IETF MMUSIC Working Group and proposed standard for initiating, modifying, and terminating an interactive user session that involves multimedia elements such as video, voice, instant messaging, online games, and virtual reality.
SIP clients traditionally use TCP and UDP port 5060 to connect to SIP servers and other SIP endpoints. SIP is primarily used in setting up and tearing down voice or video calls. However, it can be used in any application where session initiation is a requirem ....etc
