8x8, Inc. (Nasdaq:EGHT), a provider of Internet Protocol (IP) communications solutions for business and residential users, is providing voice trunking services to cloud telephony solution provider CallFire. CallFire began offering its hosted power-dialing services to small business, call center and enterprise customers over 8x8's established VoIP network last week. The agreement between the two companies links 8x8's enterprise-class SIP trunking service together with CallFire's cloud telephony platform, currently in use by more than 14,000 businesses. Initially a customer of CallFire, 8x8 noted that CallFire's voice quality could benefit from 8x8's VoIP network. By powering a substantial portion of CallFire's underlying VoIP network, 8x8 was able to combine its enterprise quality VoIP with CallFire's innovative Hosted Power Dialing platform, and now uses CallFire's broadcast services exclusively in its call centers.
