[Asterisk-Users] I need some clarification on DTMF

[Jeff Gustafson]

Hello all,
	I have a SIP provider that is doing the PSTN bridging for me
(voiceglo.com).  I understand the inband, info, etc for DTMF on *my*
network, but what about what they're sending me?  Is there anything that
could prevent them from sending me DTMF information?  The Asterisk
system is currently NAT'd (no special rules, just a Linux router) and
incoming and outgoing calls work perfectly.  The problem is the
*incoming* DTMF.  When I turn on inband DTMF, I get all sorts of false
sensing of codes.  
	Is it normally the responsibility of the SIP provider to do the DTMF
decoding instead of my side?
