[asterisk-users] Cisco 7970 - DTMF

[Tomislav Parčina]

In sip.conf for one friend (Cisco 7970 phone) I have define this
dtmfmode=inband

And in xml.conf of that phone I have 
<preferredCodec>none</preferredCodec>
<dtmfAvtPayload>101</dtmfAvtPayload>
<dtmfDbLevel>3</dtmfDbLevel>
<dtmfOutofBand>none</dtmfOutofBand>

But DTMF doesn't work for that phone.

Phone establishes call using g711 alaw codec.

How should I configure phone and sip.conf to make DTMF work?
