[SIPForum-discussion] Sdp attribute for Call hold

[tom170 at o2.pl]

Hi,

If Leg A would send inactive the second side probably replies with  
inactive too - nobody would receive media.
Music on hold could not work properly then.
Incactive can happen when the call was placed on hold by one side and then  
second side put's the call on hold as well.
In normal scenario sendonly should be sent and recvonly answered by the  
other side.
