The Need and Importance of VoIP

Importance of VoIP

Originally, one of the primary business drivers for the adoption of VoIP was saving money on long distance calls. However, increased competition in the industry drove down the cost of long distance calls to the point that cost savings alone was insufficient motivation in order to migrate a PBX-centric telephony solution to a VoIP network. However, several other justifications exist for purchasing VoIP technology:

  1. Low recurring costs: In various typical PBX (centric networks), a particular digital ‘T1’ circuit traditionally can carry either 23 or/and 24 synchronized voice calls and these are based on the type of indication that is being used. A T1 naturally had 23 or/and 24 channels available. Each and every channel had a particular and specific bandwidth of 64 kbps only and it could handle one and only phone call at a time. But, VoIP networks often leverage (codecs) coder/decoders to press the voice. Every voice call can consume only less than 64 kbps of bandwidth per call, thus allowing on-top concurrent calls, when compared to this typical type of technology.
  2. Flexibility/Adaptability: Since these VoIP networks send some ‘voice traffic’ over an IP network, the administrator has a high concentration of manage over this voice traffic. Various clients can be arranged to have access to various voice applications examples include, a messaging application or even a communicative voice response [IVR] application.
  3. Advanced features & functionality: VoIP and IP telephony networks can also offer higher and much superior features, which include the following:
    • Call routing: Obtainable and accessible routing protocols examples include, EIGRP and OSPF these can also be used to offer and supply fast ‘failover’ to a endorsement link if a most important network link failed. And on top of that, calls can also be routed over various network links based upon the eminence or the link’s traffic load at the time.
    • Security: If the attacker were to cut off and imprison the VoIP packets, he can play them backward to listen eavesdrop on a conversation, on purpose. Another famous example, a user may enter his/her (PIN) personal identification number in the bank’s specific and particular IVR system, and so as a result the attacker may catch these packets. And so attackers may begin violent rogue devices examples include call agent servers into the network and IP phones. Luckily, Cisco will offer to you a wide and large range of technology and most suitably applicable in order to further solidify the security and protection of a particular VoIP network.
    • About Messaging: An answer to such a “Cisco Unity” could also be used to supply only one storehouse for a wide diversity of such messaging kinds. Examples include a ‘Microsoft Exchange’ message store can also be used to combine the storage space of fax broadcast, voice mail and e-mail messages. Then the user can do a lot of thing, example include, call in a ‘Cisco Unity’ system and have his/her e- mail read to her by the text-to-speech conversion.
    • Solutions for Call Center: Cisco can offer a large variety of answers for ‘call centers’. Examples include, Cisco’s Contact Center Express and Contact Center solutions can smartly route-up calls that are about to come in order to appropriately call the center agents. And also because the call center will use Cisco IP Phones, geographically and location wise, these can be separated (examples include, the call center agents that are working from the home).
    • Customer-searching solutions: Several clients may wish to communicate by a particular chat-interface or even through email, conflicting to talk with a company’s client service envoy. Since a VoIP network can only work on a ‘data network’. The data network features for example e-mail and the chat feature can be incorporated into the client’s specific choice of various contact choice, thus, and increase is created in the client’s satisfaction level.
