Asterisk Wifi Portable Voice Calling System Using ARM11
International Journal of Applied Research 2016; 2(4): 567-570 ISSN Print: 2394-7500 ISSN Online: 2394-5869 Asterisk WiFi portable Voice Calling System using Impact Factor: 5.2 IJAR 2016; 2(4): 567-570 ARM11 www.allresearchjournal.com Received: 29-02-2016 Accepted: 25-03-2016 Sayyad Nikhat Parveen, Prof. Tirupati M. Goskula Sayyad Nikhat Parveen M.Tech Scholar, Electronics Abstract Engineering (Communication), An Internet Protocol Based Private Branch Exchange System consists of one or more SIP (Session Anjuman College of Engg & Initiation Protocol) phones. The IP PBX server functions in a similar manner to a proxy server: SIP Technology, Nagpur, India clients, being soft phone or hardware-based phones, register with the IP PBX server, and when user wishes to make a call user ask the IP PBX to establish the connection. The IP PBX has a directory of all Prof. Tirupati M. Goskula phones/users and their corresponding SIPS address and thus is able to connect an internal call. An IP Assistant Professor, PBX is a complete telephony system that provides telephone calls over IP data networks. Electronics Engineering (Communication), Anjuman All conversations are sent as data packets over the network. IP PBX can enable each and every College of Engg & Technology, employee/person in an organization to be provided with a voice extension, thereby multiplying his/ her Nagpur, India productivity. Easier to manage the routine operations because of web/Graphical User Interface based configuration interface. It eliminates phone wiring as it uses existing network. There is no need to disrupt current external communication infrastructure and operations Keywords: Asterisk, SIP, VoIP, Raspberry, USB handset 1. -
