Voice over Internet Protocol (VoIP)

What is VoIP?

VoIP, stands for Voice Over Internet Protocol, is a technology allows voice conversations to be carried over the Internet. VoIP exchanges voice information in digital form, in discrete packets rather than by using the traditional circuit-committed protocols of the Public Switched Telephone Network (PSTN).

Why VoIP?

  • Price

  • Flexibility

Shortcomings of VoIP

  • The quality of voice is not as good as traditional telephony. It is mainly because it is susceptible to all the hurdles of Internet connection such as latency, jitter, packet loss etc.

  • Failure of precise user tracking in case of emergency calling

  • VoIP is dependent on wall power

Current VoIP Solutions

Constraints in Current VoIP Solutions

  • Not interoperable, isolated.

  • Platform and language dependency, network complexity .

  • Heavyweight client.

  • Scalability and extendibility problem.

  • NAT and firewall traversal.

  • Emergency support.

SOVoIP Architecture

  • SOVoIP Features

  • Simplicity

  • Extendibility

  • Mobility

  • Protocol interoperability

  • Quality of service (QoS)

  • Security

  • Conferencing

  • NAT and firewall traversal

Registration Authentication

1. Call Query for CN2

2. DNS Search For PN3

3. Req. CN2’s Information

4. Return CN2’s Info.

5. Return CN2’s Info.

Figure: Call Establishment In SOVoIP Architecture.

Call Setup in SOVoIP Architecture

  • PN1 and PN2 are the nearest public and home node for CN1 respectively

  • PN3 is the home node of CN2

  • CN1 completes its registration and authentication with its home node PN2 but for call setup it communicates directly to the nearest public node PN1.

  • Steps 1-5 are user search.

  • Steps 6-9 are call setup.

  • Step 10 is real media data flow.

  • Steps 11-14 ends the call.

Protocol Interoperability and SOVoIP

  • Reduces network complexity

  • No maintenance required

  • Less bandwidth consumption

  • Secure

  • Do not required to parse the protocol specific messages every time.

  • Users themselves can switch back and forth between SOVoIP and current protocol.

SOVoIP Business Model

Figure: SOVoIP Business Model

In the model, a mobile customer from SOVoIP makes a query to the organization. The customer query is checked with the backend office system and is redirected to appropriate customer support. The support that is external, and is behind a firewall, can still assist the customer from a soft-phone. During the support customer data is available in the soft-phone via the web service interface of the organization.

Conclusion and Future Work

  • Interoperability with PSTN

  • Conferencing

  • NAT and Firewall Traversal

  • Localization services over IP network such as enhanced 911

SOVoIP is the architecture which will make sure internetworking between office, home and any other external information system and accessibility to these systems via the available hand held device.
