Our SIP carrier uses inband for DTMF tones so I’ve set the FreePBX V14 system to use inband along with the phones. The issue I run into is our VM. When I attempt to access the FreePBX VM it doesn’t recognize the tones. I’ve also added these additional settings
inband should be paired with g711 as the codec - ive read anything else delivers poor results
you mention adding settings…
typically i see the inband declaration associated with a trunk? and relaxdtmf is related to dahdi/zaptel iirc?
(those dont look right)
Those extra settings are probably meaningless I agree. It surprises me that for a local phone using Inband on a FreePBX server set to Inband when I access VM it does not recognize my Inband tones.
