Bandwidth.com Acquires Dash - Google Voice, Skype & Others Impacted

February 23, 2011

Bandwidth.com, a nationwide supplier of VoIP network services to Voice 2.0 innovators such as Skype, Pinger, and others, today announced the acquisition of dash Carrier Services (dash), a North American-based provider of tier-one emergency services and wholesale carrier voice solutions. The acquisition provides Bandwidth with a definitive competitive edge, as it will now tightly couple additional advanced services, such as E911 calling, with its core voice and SMS offerings to deliver a stronger experience for customers who would otherwise need to cobble together these services in much less efficient ways. The deal was all-cash, and the combined company is now projected to generate over $100MM in revenues this year.

Voice 2.0 innovators will increasingly need to add services like E911 calling as VoIP adoption continues to accelerate, and Bandwidth.com can directly address this need through its now expanded portfolio of solutions.

February 16, 2011

SPIRIT DSP announced today the second big news of the week. Yesterday, they announced Viber, a VoIP app for the iPhone was powered by SPIRIT DSP and now today they are announcing that Huawei Technologies has extended its license with SPIRIT DSP for HD voice and video to carriers. Interesting that I never hear from SPIRIT DSP's competitor Global IP Sound (GIPS) any more -- who at one time powered Skype.

Anyway, under terms of the agreement, Huawei, an existing SPIRIT customer since 2007, will use SPIRIT's TeamSpirit Voice&Video Engine PC in its IMS (IP Multimedia Subsystem), Unified Communications (UC) and Fixed Mobile Convergence (FMC) solutions to carriers from the Huawei core network, delivering a PC video softphone to Huawei's carrier customers.
