struct offered_media offered_media[4] |
When receiving an SDP offer, it is important to take note of what media types were offered. By doing this, even if we don't want to answer a particular media stream with something meaningful, we can still put an m= line in our answer with the port set to 0.
The reason for the length being 4 is that in this branch of Asterisk, the only media types supported are image, audio, text, and video. Therefore we need to keep track of which types of media were offered.
Note that if we wanted to be 100% correct, we would keep a list of all media streams offered. That way we could respond even to unknown media types, and we could respond to multiple streams of the same type. Such large-scale changes are not a good idea for released branches, though, so we're compromising by just making sure that for the common cases: audio and video, audio and T.38, and audio and text, we give the appropriate response to both media streams.
The large-scale changes would be a good idea for implementing during an SDP rewrite.
