Telephone service companies have created a special communication service without the need to use customer's equipment. It's called a "virtual number". It also has a text type of "virtual SMS center." Thanks to the virtual link you can make calls or send messages while connected to the equipment of the company.
Telecom Call Center services are based on SIP platform for access and Class 4 Switch for multiprotocol interconnections with all major fixed and mobile operators from Romania and worldwide.
