[asterisk-users] DTMF Talk Off

[Sam]

I am having some issues with dtmf beeping while in conversation.  This 
is a simple home setup using asterisk 1.4.21 and a grandsteam 286 ATA 
with a cordless phone.  I have played with the relaxdtmf setting in 
sip.conf.  Setting it to yes made it worse which makes me think that the 
issue is coming from asterisk and not the ata.  And all the dtmf modes 
are rfc.  Any one have any tips to further trouble shoot this?
