Gizmo5 has signed up with Jajah, making it the third VoIP player to turn over their VoIP-PSTN interconnect infrastructure to the company.

Jajah will handle all call termination for Gizmo5, as well as additional services including customer care and billing. Gizmo5, formerly known as the Gizmo Project, was founded by tech maverick Michael Robertson and uses open standards such as SIP and Jabber along with a dash of P2P to connect VoIP calls. Calls between clients are free, but in and outbound calls are billable. According to Gizmo, they have "millions of users" doing calling and IM; outsourcing to Jajah should save them money and give them a better deal on calling rates.

Gizmo5 joins Yahoo and MailVision in farming out their call handing to Jajah, boosting Jajah's standing as the place to go for managed VoIP services when it comes to soft phones.  Yahoo turned over its VoIP operations to Jajah at the end of April while MailVision signed up last week.
