1) VoIP is inevitable: AT&T and Verizon are offering big-business VoIP services. They are upgrading their networks with Multiple Label switching, which gives a different ways to IP according to their priorities. They are implementing IP Multimedia Subsystem to provide wired and wireless services to use VoIP technology including videoconferencing, instant messaging, and presence awareness.

For the big companies when their PBX telecommunications reaches at the end of cycle, they need to replace with new equipment. Therefore, it does not make any sense to move their technology into VoIP technology, if their PBX gear is not able to relocate or adding offices. Instead of this, they make link between interface cards or gateways with PBX, which will enable IP.

According to TEQConsult Group, the telecom and networking companies made IP telephone ports more than 4.3 million, which is 40% more from previous year.

2) It is not as cheap as you think: The VoIP experts and consultant charge more than $100 and up an hour. Even after installment, the charges of maintenance and management are also goes to add.

The installment of 100-phone will cost $155,000 just to get it and run it, while for 500 phones which includes IP PBX phones, training, switching and cabling costs is approx $575,000. To install VoIP is more costly than IP PBX phones.

3) Tricky Deployment: VoIP is not so easy, that you install and start working, as you do in PBX. As the companies are not using standard system, VoIP is not easy to switch in hardware. Firstly VoIP would not simplify the network management. To maintain the quality of VoIP network is tougher than conventional voice networks. If data packets are dropped, it just means slight loss in performance, but it drops in VoIP, there is loss in quality as well as calls.

4) VoIP security is dodgy: VoIP technology has not experienced big security vulnerabilities. An attacker use the open source Ethereal network protocol analyzer program to capture to dump network output files and then use the open source voice over miss configured Internet telephones program to make a .wav file that includes VoIP phone conversations. There is a establish way to hack the VoIP calls.VoIP attackers also could flood networks with bogus voice mail messages.

5) Starting of cheap calls: According to 60 per cent respondents, they are implementing VoIP to make low cost calls. Approximately 41% respondents are using VoIP and 57% of respondents are interested in pursuing unified voice, data sharing, e-mail, and/or conferencing. VoIP enables companies to introduce number of applications.

VoIP offers the presence awareness, the ability to transmit the availability of ones and willingness to communicate. In the beginning of installment, companies have to make balance between installation costs and in upgrading features. So basing a deployment on them is high risk.
