The connection to Telecom Call Center gives Resellers and Retail customers the benefits of a global network without building and managing it themselves. Service Providers also receive the benefits of the direct interconnections with world’s leading telecommunication carriers.
We are able to collect your calls using VoIP (H.323 and SIP protocols) coming from any spot on the globe through Internet as well as through PSTN.
How does it work?
The communication system we have built interconnects many different world’s leading telecommunication carriers. Its unique intelligent routing engine is able to apply for each incoming call the best route using multiple different criteria (even customer’s feedback!) depending on the type of service you have chosen and subscribed.
