Verizon Global Wholesale is now offering additional functionality for three of its product platforms — SIP Gateway Service, Advanced Toll Free IP Termination and Carrier IP Termination Transport. This new functionality enables the product platforms to share a single, secure virtual private network connection called an IP Security (or IPSec) tunnel.
According to Mike Yancey, director of wholesale voice services for Verizon Business, Verizon bypasses other security protocols in favor of IPSec tunnel because it offers the greatest level of flexibility.
An IPSec tunnel maintains integrity and confidentiality because all data is encrypted prior to transmission, then authenticated upon receipt to verify the data has not been altered. The source of the data is also authenticated to prevent the possibility of such security breaches as "spoofing" an IP address – a fraudulent network technique in which a program or person masquerades as another.
Verizon’s SIP Gateway Service comes in four configurations: Inbound Complete, Two-Way Local, Two-Way Complete and Outbound. These services are complemented by Carrier IP Termination Service. This offering allows customers to take advantage of the cost savings of originating long-distance traffic and terminating that traffic via SIP protocol over a global network.
The company’s Advanced Toll Free Service allows U.S.-based customers to support toll-free calling solutions on a global basis. The service supports in-country toll-free dialing outside the U.S. across more than 80 countries and Universal International Freefone Numbers across more than 40 countries.
