Incoming calls via IP
Compatibility:
PortaNet supports a proprietary IP streaming protocol, only
compatible with Prodys IP audio codecs. In addition, support for industry-
standard algorithms is provided under the ‘Streaming Protocol’ tab in the
Configuration window of PortaNet web page. A preliminary version of all
protocols defined as ‘mandatory’ by the EBU group in their N/ACIP (Audio
Contribution Over IP) project is supported. This project defines the standard to
achieve interoperability between audio codecs over IP.
