I can’t figure this out. Some help here would greatly be appreciated as I know not where else to post.
If I make a call through my AudioCodes MP108 to an external AutoAttendant that requires I make a selection in the menu from my keypad it doesn’t work. I know it is this particular piece of equipment because If I call from the same phone through the same PBX (Asterisk) and use a different gateway the call is successful.
What setting must be made in the AudioCodes setup in order to allow this sort of scenario?
audiocodes:
Use Out-of-Band DTMF = No
Out-of-Band DTMF Format = Info. (Cisco)
Declare RFC 2833 in SDP = No
DTMF RFC 2833 Negotiation = Disable
RFC 2833 Payload Type = 101
sip.conf
dtmfmode=inband
and maybe
relaxdtmf=yes
or (better way)
audiocodes:
Use Out-of-Band DTMF = Yes
Out-of-Band DTMF Format = RFC2833 (i don’t know if thats the right way to declare it)
Declare RFC 2833 in SDP = Yes
DTMF RFC 2833 Negotiation = Enable
RFC 2833 Payload Type = 101
sip.conf
dtmfmode=rfc2833
or
dtmfmode=auto
basically- dtmf payload type for rfc2833 should as i recall always be 101. it shouldnt declare rfc2833 if its not going to use it (use out of band dtmf=off) and if its going to / not going to send dtmf as RFC2833 then Asterisk should know this.
Also I’ve never dealt with audiocodes stuff so i dont know if I’m doing those configs right but hopefully you get the right idea?
