ISP-EURONET, a 3CX Premium Partner in Steinbach near Frankfurt am Main, Germany, provided an offer to Chip One in early March 2011. Chip One selected 3CX Phone System over Siemens and Swyx systems, and on 22 April 2020 the company awarded ISP-EURONET the contract for 3CX Enterprise Edition 128 CC and 64 CC. ISP-EURONET implemented 3CX Phone System in Chip One offices in Neu-Isenburg, Germany (its headquarters) , Hong Kong, Los Angeles and Shenzhen, ultimately bridging all their 3CX Phone System installations. The entire project was completed quickly and successfully, without any disruption to daily operations at Chip One.
