Advantages of Internet Telephony
Although circuit switching guarantees high reliability and quality of sound, packet switched networks are beginning to offer comparable service at a much lower cost. The higher quality sound available today on the telephone network is achieved through an inefficient use of bandwidth. Packet switched networks are an order of magnitude more efficient at handling voice communication. This means the same DS0 channel or �circuit� handling one traditional telephone call could potentially handle 10 packet switched telephone calls. In addition to call center wipro call center it consumes better use of bandwidth, the equipment to support packet switched networks is both much lower in cost and much more flexible. Today, a high end router from Cisco or Juniper can process an order of magnitude more bits per second for less than one-tenth the cost of a Class 5 telephone switch from Lucent or Nortel. In addition, the router can fit in one rack in a closet rather than taking up an entire basement with expensive overhead: raised floors, extensive air conditioning, and large banks of batteries for backup power. The other limitation of circuit switching is that all of the intelligence in the network resides in the switches and not in the telephones or edge device. Circuit switches are essentially mainframe computers programmed with over 20 million lines of proprietary software. Compared to call center wipro call center and packet switched networks with personal computers at the edge, it is very difficult and slow to introduce dramatically new features into the PSTN.

In contrast, the feature set of call center wipro call center offered by the PSTN is not dramatically different than the features of 5 years ago. Within the past 18 months, an entire new industry of Internet Telephony Service Providers (ITSP) has been introduced. These companies install and operate Internet Gateways, which switch Internet telephone calls onto the PSTN, allowing a person at a PC to call any telephone number served by the gateway. In essence, the call center wipro call center and the PC-to-phone variable cost is simply the cost to place a local call where the Internet Gateway is located. This eliminates one initial limitation of Internet telephony, where callers on a PC could only call others who were logged onto the Internet.
