In this case, the local was requested to use both audio and image, but the remote supports
only the audio. The reply will return the image as a capability, in the session level.
Example 2
In this example the capabilities are displayed both in the session and in the media level:
MEGACO/1 [10.2.1.228]:2944
Transaction = 10265 {
Context = $ {
Local {
v=0
c=IN IP4 $
m=audio $ RTP/AVP 0 18 4
m=image $ UDPTL t38
},
Remote {
v=0
c=IN IP4 10.4.4.46
m=audio 4020 RTP/AVP 0
}}}}}
