The benefits of IP Telephony are many. These include:

• Reducing infrastructure - no need to have individual telephone lines delivered to each desk, use your data network for both voice and data.
• Increased functionality - integrating voice into your applications, making use of features such as "click to dial" within CRM systems.
• Flexibility - extension mobility allows you to log in to any phone in the company and have all your calls and voice mail delivered to that handset.
• Cost savings - direct all your internal calls via your data network instead of the PSTN (also known as toll bypass). All calls from branch networks can be centralised to a single ISDN bank at your head office.
• Management - moves, additions, changes to your voice network become as simple a configuration change in a management interface
