Dedicated solution for fixed telephony

SIP Trunking

What is the SIP Trunking service?

The service offers a fixed telephony solution, which allows the transmission of a large number of voice channels through a single IP connection.

It can be offered with both geographic and non-geographic numbering.
The voice platform is connected to other national and international operators, offering availability to and from all operators with whom Orange has concluded an agreement.
The security and protection of confidential data are ensured by the state-of-the-art MPLS network, through specific protocols and mechanisms for encrypting and transmitting information. The solution offers the ability to separate data traffic from voice traffic, bandwidth sharing (optimization of voice resources), as well as scalability and centralised monitoring.
