I am glad to tell you that I have found the solution.
the problem is :
A is pjusa, B is another sip phone.
A is talking with B, B press hold key, then A start to listen to hold music.
After a while, B press unhold key, music stop.
Then B can hear A's voice, but A can not hear B's voice.
The solution: A also press unhold key( input "v"), then everything is ok.
I don't know where the exactly problem is?
The Server is asterisk, and set canreinvite=no
?2008-04-04?ofn at keystream.se ???
In the re-invite and corresponding OK there should be a sendrecv
attribute for media just check if it's present.
