I got a lot of this waring on CLI(Asterisk 1.4):
Also, the IVR seems also get trouble because of this. When caller press a key it sometime generate 20+ lines of the above warning.
I tried to enable SIP debug but it won’t give me more info. I really don’t understand what cause the warning.
My phone is connected through Linksys PAP2. So I tried to change the PAP2 under SIP -> RTP Packet Size. I tried 0.010, 0.020, 0.030(default), 0.040 and it doesn’t make any difference.
