IP PNC allows S8700-series Servers and G650 Media Gateways to be connected over IP networks. Avaya Communication Manager uses a proprietary method to package signaling messages over IP. This method allows deployment of communications systems throughout a customer’s data network.
H.248 Media Gateway control
Communication Manager uses the standards-based H.248 media gateway control protocol to perform call control of Avaya G700, G350, and G250 Media Gateways. H.248 defines a framework of call control signaling between the intelligent servers and multiple Media Gateways. H.248 controls both IP (H.323) and non-IP connections into a media gateway. H.248 has been extended by Avaya to also tunnel proprietary CCMS messages, to allow for enhanced call handling.
