"Over the weekend we came up with the idea of a speak-to-tweet service -- the ability for anyone to tweet using just a voice connection," they said.
Voice mail messages left at +16504194196; +390662207294 or +97316199855 will instantly be converted into text messages, referred to as tweets, and posted at Twitter with an identifying "hashtag" of #egypt.
Twitter hashtags are intended as search terms so people can more easily find comments related to particular topics or events.
