Global Crossing introduced a new inbound service portfolio for carriers that consists of two components:
- Global Crossing VoIP DID, which provides carriers with local origination for nationwide local numbers through a single IP point of interconnection as a lower-cost alternative to traditional toll-free applications. This service eliminates TDM, private line and foreign exchange service fees by providing a single IP connection alternative. The service is generally available now in all major U.S. markets while Global Crossing VoIP Toll Free Transport is available throughout North America.
- Global Crossing VoIP Toll Free Transport provides carriers with interconnection, transport and termination of 800 packet-based voice traffic for calls originating as TDM, thereby eliminating the need for capital- intensive IP to TDM conversion gear.
Incoming DID and toll free calls originate as TDM calls and are converted to IP when they reach the Global Crossing voice network, and then are routed directly to the carriers’ IP network through a SIP-based IP interconnection. DID numbers can be purchased directly from Global Crossing or can be ported from third party providers to Global Crossing. The new enhancements also enable Global Crossing to offer two distinct routing options for international termination.
Additionally, carriers now have a choice for domestic and international voice traffic termination through uncompressed audio (G.711) for highest quality voice traffic, or compressed audio (G.729a) that increases voice traffic capacity by 60 percent. In addition, Global Crossing is now able to support the international standards for compression with silence suppression (G.729ab). The greater circuit efficiency of G.729 enables small- to mid-size resellers such as IXCs and other service providers target non-compression sensitive applications. http://www.globalcrossing.com
