Table 45: Media Reactivation Parameters
Parameter Description
Enable A media reactivated in an incoming answer is ignored. This behaviour goes
against the SDP Offer/Answer model described by IETF RFC 3264.
Disable A media reactivated in an incoming answer ends the current media negotiation and
the call. This behaviour follows the SDP Offer/Answer model described by IETF
RFC 3264.
Table 46: Audio and Image Negotiation Parameters
Parameter Description
Enable The unit offers audio and image media simultaneously in outgoing SDP offers and
transits to T.38 mode upon reception of a T.38 packet. Also, when the unit answers
positively to a SDP offer with audio and image, it transits to T.38 mode upon
reception of a T.38 packet.
Disable Outgoing offers never include image and audio simultaneously. Incoming offers
with audio and image media with a non-zero port are considered as offering only
audio.

Setting” on page 270 for more details.
