The innovaphone IP gateways act simultaneously as an interface to other networks and as a hardware platform for the innovaphone PBX, also offering a Unified Communications solution. They can also be installed as Session Border Controller (SBC) and Reverse Proxy in combination with other functionalities or as a dedicated device. All IP gateways are robust and their hardware works without the need for hard drives and fans, thus ensuring an optimal level of performance, even when they simultaneously develop the functions of IP PBX and Unified Communications. The gateways differ depending on the type and number of interfaces they have, which are activated through licenses. In large installations you can join as many IP gateways as necessary.

In scenarios of migration to a pure IP trunk (All IP), innovaphone gateways make it possible to install in parallel with ISDN lines and SIP trunks. In this way, they allow to prolong the trial process and ensure the success of the final migration and also to do it in a very progressive way.

All the gateways that serve as a platform for the innovaphone PBX or PBX are equipped with an internal slot for a mini SSD card. The capacity of the gateways also allows the parallel use of the Linux API, thus, the number and scope of the additional allocations is almost infinite.

Through the innovaphone PBX or PBX it is also possible to make teleconferences with multiple participants.
