MWI Notify Error on Audiocodes MP124

Asterisk Asterisk Support

Hi Guys,

I?m having problems configuring MWI on my Audiocodes MP-124 FXS. When my Asterisks send the “Notify” command to the Audiocodes, It responds with a "481 Call/Transaction Does Not Exist"
I?m using Asterisk 1.2.9.1.

Best regards,
Mariano
