Dual Operator

Welcome Italia has developed a special installation procedure that assures you Voice service continuity during the transfer of your telephone lines from your former Provider to Welcome Italia.

This procedure provides for the duplication of necessary resources (equipment, ports, etc.) so as to dispense with the need for the presence of technical staff on the day of the transfer of the lines from the old Provider.

  • monthly rate: included
