GXW4232 - Key presses ignored during call


I am configuring a GXW4232 with Asterisk 13, I can make and receive calls normally, but any function during a call is ignored, for example, I can dial * 97 to open the voice messages, but when I type 1 to listen to the message, the menu continues as if you have not typed anything. Similarly if you try to transfer a connection with *2 or ##, the commands are ignored. I checked the Asterisk logs and it does not receive any commands when typing during a call.

Any help will be welcome.

Thank you.


the gxw supports several methods of dtmf, try using inband.


It was configured with “In-Audio”, I changed to “RFC2833” and now the keys work. Thank you.
