Polycom HDX provides in-band SIP signaling as per RFC 2833 to transport DTMF audio tones from Polycom HDX systems to the remote SIP device (for example, a SIP registrar server or a SIP bridge). This feature allows Polycom HDX systems in point-to-point calls to access telephony features that are based on transport of DTMF tones to the remote SIP servers or bridges unable to process DTMF tone signaling via the audio channel.
Polycom HDX supports full-intra-frame messages and flow-control messages, both of which are sent from the receiving endpoint to the transmitting endpoint through the RTCP port associated with the RTP video channel.
In Polycom HDX you can enable both IP H.323 and SIP at the same time. Both IP H.323 and SIP are enabled by default.
