[11] Birch has regional operations centers in Atlanta, Macon, Georgia and Emporia, Kansas[1][3] with approximately 1,400 employees.

[13] In 2003, Oddo "implemented a major shift in business strategy," and focused on building out the size of the company's IP network through acquisitions.

[18] Access purchased local, long-distance residential and SMB customers in Florida and Georgia from IDT Telecom in April 2007.

[19] The final transaction took place for an undisclosed sum in February 2008,[20] with the new combined annual revenue of the companies reaching $200 million.

[16] Vincent Oddo retained his role as president and CEO of Access, with no layoffs announced as part of the merger.

[19] In late 2008,[14] Birch Communications Inc.[20] purchased approximately 30,000 business access lines from North Little Rock, Arkansas-based Navigator Telecommunications for an undisclosed sum.

[21] The acquisition increased consumer density for Birch in existing markets and allowed it to expand into California and Arkansas.

[20] The acquisition of Cleartel Communications in August 2009[14] added around 100,000 business and residential sites to Birch’s customer base as well as facilities in Florida.

[6] The company announced that some of the funds would be used to finance further acquisitions, with a Birch spokesman explaining that "we've gotten very good at integrating new customer bases into our systems and not increasing our [operational] costs.

"[24] In October 2011,[14] 56,000 business and residential access lines in the Orlando, Florida area were added to Birch's network, with the acquisition of Cordia Communications for $8 million.

[6] By November 2011, all excluding two of the 12 acquisitions made by Birch since 2001 (Acutel and Cordia) had been "funded through its own profits and from the bank accounts of Oddo and his partners.

[14] The assets included an IP network spanning the Tampa Bay, Florida area[5][26] and was Birch’s fourteenth acquisition since 2006.

[27][28] The deal expanded Birch’s small and medium business customer base in southwest Florida and other parts of the southeastern United States.

[31][32] The strategy targeted companies that would increase customer density and expand Birch’s network near existing markets.

[5][33] Covista Communications was a facilities-based telecommunications service provider with business and residential customers in 48 states,[34] and large switching centers in Tennessee and New York.

Birch also alleged that Rightscorp was trying to exploit a lack of knowledge among smaller regional ISPs that DMCA subpoenas are not applicable to peer-to-peer file sharing.

[47] As a result, at the time Birch served 686 buildings nationwide with its fiber network, also reaching around 20,000 businesses with ethernet and voice services.

[55] Focusing on both residential and business clients, Birch Communications offers services such as "local and long distance voice, broadband Internet access, T1, PRI, bonded T1, mobile voice and data, e-mail, voicemail," and prepaid phone services in each state, Canada, and Puerto Rico.

[56] Other Birch product brand names include BirchCloud, BirchVoice, BirchNetwork, BirchMobile, and BirchIT Services.

[58] The company also introduced a new BYOD program, allowing customers to use their own SIP-compliant handset devices with its TotalCloud PBX offering.

[59] Rather than through the public internet, Birch voice and data services are typically delivered using VoIP technology on the company's own IP-Network.

There are six main data centers throughout the United States, and Birch connects to 400,000 fiber-lit buildings with 31,000 fiber route miles.

[64] In February 2016, Birch donated PCs and laptops to the Metro Atlanta Task Force for the Homeless to be used for job-training at the Peachtree-Pine shelter.
