SendHub, the messaging startup that allows businesses to communicate with customers through SMS, is expanding its service today to include support for voice calls and voicemail. These new features put SendHub in more direct competition with Google Voice, as users will now be able to use their SendHub phone numbers to both make and receive phones calls, while keeping their personal cell numbers private. Although the company only has an iPhone application and online service currently, these voice calls can be initiated and received on any device that supports messaging – even on feature phones.
