Few Myths about hosted VOIP Services

VOIP ( Voice over Internet Protocol) normally gives impression about very low cost, unreliable voice communication system which works on any type of internet connection. Sinc internet itself is a new technology, people always thought VoIP to be very high tech, difficult to set up and use.

With advent of cloud services in voice services, VoIP is also being used by many hosted IVR service providers as an low cost alternative to traditional TDMA telephony.

Here are few myths about VoIP used in Hosted in Voice Services:-

1. VoIP is unsafe and anybody can hack into it

One of the most circulated myth about VoIP is that it is unsafe to use VoIP as voice communication media it is easy to eavesdrop. Actually, it is far from truth. VoIP being digital, it has the highest possibility of encrypting its voice data depending only on the computational power as well as bandwidth requirement. Even CIA ( Central Intelligence Agency) of USA has resorted to cloud calling on Amazon’s Web Service platform.

So, one should be assured that VoIP is safe, secure and there is very less possibility of anyone being able to eavesdrop.

2. TDM Systems or Conventional Telephony has better ROI

VoIP is a future technology as exchange of data over large distances would remain in the technology space for years to come. So, VoIP, which like any other data transfer over large distance in nearly real-time is almost a future proof technology. TDM or traditional telephony system may go obsolete once in future as no new innovation or utility is now possible in TDMA. IP is the evolving technology. So, investing in VoIP might give better return.

3. Hosted VoIP based Voice Service is difficult to use

Actually, traditional Telephony System is much more difficult to set up. It requires a highly qualified telecom engineer to setup any TDM based system and it may also encounter many compatibility issues among different hardware of different manufacturers. It happens because it has many protocols like ISDN PRI, R2MF, SS7 etc.

While VOIP uses very few protocols and it is compatible with any hardware as long as they have the same protocols available in it.

So, most probably, it is time to evaluate and plan a migration to VoIP based hosted IVR solutions!

    Do you have TDM v/s VOIP bandwidth consumption based on codec? for your reference i am showing VOIP bandwidth coded chart. Do you have server performance chart based on codec?

      We are using G.711 codec for TDM which is full 64 Kbps. Our service providers provide E1 lines with G.711 simple codec. Each of our servers are well equipped to handle 1000 TDM calls in parallel without consuming significant CPU resources.
      For VOIP solution, we use auto scalable model, as the call volume increases and if the current servers load reaches to a threshold value, automatically new server is spawned to take care of extra load.

      • Bhaskar says

        G.711 codec widely used for TDM as well as VOIP channels but for proving VOIP new generation technology which mainly used for low cost effective bandwidth usage we require test report, comparison report on various stages such as traditional TDM V/S VOIP codec report, server utilization test report based on TDM and VOIP, Telecom Operator voice quality performance report, SI hardware cost saving report. On this basis VOIP technology can be easily spread in telecom market. For this i gave you VOIP bandwidth usage report now you need to add few more reports as given above then it will be useful for all readers.

      Hi Bhaskar,
      Thank you for the information.

      Agree that VOIP uses high computational power of the servers, but cost of server is going down while computational power is increasing. Same can not be said about CTI hardware as well as other telecom equipments. So, most probably, VoIP is the future.
