Palo Alto -based Jaxtr, allows you to receive phone calls by embedding some code in your profiles on MySpace, Friendster, hi5, Piczo and the rest. It’s like a widgetized version of Jajah: your visitor enters his phone number and receives a call. Once he picks up, your phone starts ringing, and the call is connected. If you don’t answer, Jaxtr will take a voicemail message, and there are tools to block unwanted callers or only allow certain friends to call. The caller’s phone numbers are never exposed to one another. If you don’t want to use the widget, you can put a link in an e-mail signature.

Possibly Myspace users will take to Jaxtr as there are no direct competitors at the moment, despite the fact that there are plenty of startups tying mobile to MySpace - Abazab, Umundo, Supcast, Nakama, Kindfish, FotoDunk, EQO and more. Most of these are concerned with sending media or text messages to your MySpace page, rather than direct calling. So for now the future looks bright for Jaxtr.
