The main benefits in all the above cases is cost saving. Other advantages include:

• Simplification of the network as one can develop an integrated infrastructure for all the corporate needs.
• E-commerce (now V-commerce): in traditional e-commerce, the customer can obtain the information from the supplier and place an order. The customer can talk to the supplier's representative by making a normal telephone call. Now voice enabled e-commerce or V-commerce is catching up wherein a customer can make a voice call through the voice over IP infrastructure and interact with the supplier.
• Integration with unified messaging: this service is catching up very fast.
• For example, email stored in the mailbox of the corporate server can be accessed from one's telephone at his/her home. The email will be converted to speech form using a text to speech converter and passed to the telephone. Similarly, fax message can be converted to email form etc.
