Hi all-
We recently had to switch all of our 420D handsets to use inband DTMF signaling in order to get them to work with an external door buzzer (you press "9" on the keypad to buzz in someone calling up from outside). However, this setting no longer works with Trixbox voicemail, only RFC 2833 seems to work. Is there a way to get Inband signaling working with Trixbox?
Thank you,
Darren David
