> I have a new deployment consisting in an Asterisk IPBX (LTS 11.2.x) and 20 nortel I2004 phones (black and chrome).
> Everything work's well except the fact that:
> 1. when i try to make a call and in the same time i receive a call, the two nortel phone start audio communication (unwanted autoanswer) while the fist phone keeps ringing (i heare both the tone from the line and the caller voice)
> 2. in the same enviorement if i try to reject the call by presing the hook, i can see on asterisk cli some response but the calls is not rejected and both phones restart, sometimes even asterisk restart itself.
> Using SIP channels this problem dosen't exist. it only afects unistim to unistim communications.
>  I tried with asterisk 1.8.15 and this problems are gone. But if i press a key when two i2004 are in conversation the dtmf code is transmited in a loop and the sistem crash for botah asterisk 11.2 and 1.8.15
> Thank's for help. Sorry for english.
