[asterisk-users] SIP NOTIFY

[Giedrius Augys]

Hi,
 I have trixbox and Audiocodes MP-124 FXS. In Asterisk console I often get
this message:
 Got SIP response 481 "Call/Transaction Does Not Exist" back from
86.38.10.233
So I have traced the sip packets, and I saw that Audiocodes MP-124 FXS sends
this message ė81 "Call/Transaction Does Not Exist", because Asterisk sends
him NOTIFY. So my question is how to turn off this notify?

Asterisk IP : 86.38.10.227
MP-124 IP  : 86.38.10.233
