1) IP Telephony :

PAWAN has centralized network architecture. It consists of call manager at the central site, IP telephone users spread across the network. The IP telephones are   connected to the Soft Switch either using LAN if the user is located in the LAN or WAN if the user is located remotely. The WAN network has been built for data traffic and is being used to connect the IP phones located in the remote sites. The same IP WAN also carries call control signaling between the central site and the remote sites. Centralized system also supports termination of PSTN lines, call processing of both PSTN and VoIP calls can be done using call manger. Cisco Call Manager has been implemented for managing IP Telephony. The centralized call manager controls the entire IP telephony network. It performs the major tasks such as Call Processing, Controlling, Switching, etc. In this model, the remote sites rely on the centralized call manager to handle their call processing.  Routers that reside at the WAN edges require quality of service (QoS) mechanisms, such as priority queuing and traffic shaping, to protect the voice traffic from the bursty data traffic across the WAN. The primary advantage of this model is centralized call processing that reduces the equipment required at the remote sites and facilitates to have Unified Dial plan across the network.  The architecture is centralized in nature. All the call processing engine & Soft Switch is located at the SNC, while IP telephone users are spread across the LAN and WAN. Call server/ call manager is used as IP PBX and performs the Call processing and Call control Functionality. IP Phone is being used for the Office communication.
