[Asterisk-Users] DTMF Not working for only one number

[Aaron Daniel]

No, all incoming calls DTMF works as far as I know (sometimes they just 
don't tell me).  However, there are two numbers that I know of on the 
outgoing leg that don't work.  What's strange, is that they work fine on 
the system we're passing through (we're hooked up to a meridian), but 
won't work on Asterisk.
