IP

solutions provider, Global Crossing (
News -
Alert), has announced that ABA Net, a long-distance telecommunications service provider, is using a new complementary capability to Global Crossing Carrier Outbound VoIP

Service to provide voice service for ABA Net's customers in the United States.
This new capability, called Global Crossing VoIP Pseudo Carrier Identification Code (CIC) Service, improves the hand-off of switched access calls that are transported on the Global Crossing network, according to Global Crossing officials.
Officials explained that this is done by using a Session Internet Protocol (SIP

)-based interconnection, which provides “networking efficiencies and design flexibilities for carrier customers.”
Once a VoIP Pseudo CIC call is received, officials pointed out customers have the option to use Global Crossing Carrier VoIP Outbound Service to deliver the call to its destination.
“Using Global Crossing's extensive VoIP services capabilities -- especially VoIP Pseudo CIC -- has helped us achieve more than 25 percent infrastructure cost savings and simplified vendor management by reducing the services and equipment we purchase from other companies,” Mirsad Causevic, president and CTO at ABA Net, commented in a statement.
He also said that during ABA Net’s conversion from Signaling System 7

technology to IP-based SIP, Global Crossing managed the company’s migration to Global Crossing VoIP Services.
“As carriers and resellers continue to evolve their networks to a converged IP-based infrastructure, they require flexible migration options and alternative interconnection methods for their switched access origination services,” noted Gary Breauninger, chief marketing officer at Global Crossing.
He added that the combination of Global Crossing’s VoIP Pseudo CIC service and thorough migration process -- that includes full interoperability lab testing of equipment -- enables carrier customers to “easily migrate to a converged IP infrastructure and reap the benefits of convergence.”
Global Crossing Carrier VoIP Services use Global Crossing’s integrated IP and TDM

platforms to provide wholesale IP interconnection, transport, and call completion of packet-based voice traffic.
