[asterisk-users] Re: Sangoma A200D and DTMF Detection

Thanks Rana,

We got a prompt response from Sangoma and gave them SSH access to 
troubleshoot the issue.  Modifying relaxdtmf on its own did not help but 
if used in combination with rxgain it made all the difference.  The 
system is working pretty good now with these two modifications:

relaxdtmf=yes
rxgain=6.0
