SIP Audio Codec Server

The SIP Audio Codec Server family with aixtream COMPACT inside is the most flexible SIP communication platform available. They cover the full range from studio-based bidirectional communication to use as full SIP hubs for dozens or hundreds of SIP calls. But regardless of the scale of your use case, you get a SIP audio machine that is fully standards-compliant, professional but also highly adaptable. This also includes many automization features that enable SIP Audio Codec Servers to be used as answering machines for studio and broadcast situations.


With Ferncast’s SIP family you get one of the most flexible and efficient SIP communication platforms on the market. Unlike other products, the SIP ACS is not limited to a specific input/output scenario as it benefits from aixtream’s great flexibility in the handling of inputs/outputs. Users can use it to bridge or gateway any input into SIP and vice versa. The audio signals from the incoming SIP audio can be used in various ways (recording, transcoding, etc.). The flexibility in regards to inputs and outputs also ensures that it will fit seamlessly into your environment.

All professional de/encoders are supported and thanks to Ferncast’s commitment to compatibility, communication with remote devices from other vendors is hassle-free. In addition, an expansive suite of monitoring and control features based on REST API, SNMP, Ember+ and NMOS ensure reliable operation. This makes the ACS product family a reliable SIP work horse.

Supported backup concepts include the option of having multiple devices registered to the same SIP account, so should one device fail, you can make the call on the backup device. 

In the case of full hardware failure, bought software licenses can also be transfered to a different hardware platform. If you are especially concerned with redundancy, make sure to pick a Redundant ACS.

Smart Control Applets can be used to configure answering machines and other automization. Users can create their own virtual sound mixing and control station.

We also support our SIP customers SIP accounts and IDs on our very own SIP server. Customers who have bought a SIP communication platform from us, benefit from a discount when renting SIP accounts from us.

Audio Codec Servers are available for other applications and multiple applications can be combined in a single device.
