The offerings for Asian and European markets are to based on the company's CallVantage service, whichin March and last month. CallVantage is designed to enable workers to use VoIP from their homes or hotels over available broadband connections.

VoIP has been gaining popularity as a way to cut costs by sending calls over IP-based networks--the Internet or private corporate networks--rather than over traditional landline systems, which are heavily regulated and taxed. Drawbacks of VoIP include spotty voice quality, the lack of battery backup to phones and problems with the routing of 911 calls.
This week,launched an inexpensive package for long-distance calling via IP, and unveiled a VoIP service that includes 100 free minutes monthly.
As more start-ups have launched such services, mainline carriers have jumped on the VoIP bandwagon. Over the last year, AT&T said, the number of its business customers using its VoIP services has jumped four times.
"If the promise of IP can be harnessed with remotely deployed employees and combined with a robust portfolio of VoIP-enabled networking solutions, it will positively influence a business's return-on-investment model," Cathy Martine, AT&T's senior vice president for Internet telephony, said in a statement. "This, in turn, should stimulate more demand."
