Telephone operators seeking to stand out in the crowd of voice service providers can profit from the great value offered by CreaLog’s advanced number translation service. Its compelling benefits include:

Based on the CreaLog IN platform as a powerful base we offer solutions not only for the routing of calls alone but also including IVR (Voice Portal) and Contact Center functions to perform the desired tasks in a most efficient way. This allows to connect subscribers within enterprises with ease, even if these subscribers are in different locations or working in home offices. 

Using unified numbers for mobile and fixed networks in a Fixed-Mobile Convergence (FMC) positions puts the Telco even further ahead in the strive to serve as the unified communications service provider for his corporate customers.
