Many large companies have extensive data communications networks internally and across sites.
No need to spend extra for voice services, use existing network for VoIP services.
Advantages:

• Migrating from copper-wire to VoIP over data network
• Better use of bandwidth
• Lower cost – no duplicating services
• Unified communication systems – single infrastructure to manage
• Dual-mode phones – use VoIP on internal network then switch to external network
