Empresas de nueva creación


Una de las soluciones óptimas para las startup y empresas de nueva creación es disponer de un servicio económico que cubra la telefonía y la recepción de llamadas.

Resolución de incidencias

Uno de los factores más importantes en el soporte telefónico es la capacidad de resolver peticiones en el menor número de llamadas. First Call Resolution (FCR), o resoluciones en la primera llamada es un elemento vital para valorar el servicio de atención al cliente.

Numeración telefónica virtual


Hoy en día la numeración telefónica con prefijo geográfico (91, 93,...) ya no está asociadada a una línea física. Gracias a la telefonía IP podemos recibir llamadas de múltiples números con distintas localizaciones tanto a nivel nacional como internacional.
