Summary:                    Inband DTMF not working between asterisk servers
Description: 
I have two asterisk servers MG1 and FS1.  On each server I have a SIP user
configured for dtmfmode=inband.  FS1 has an IVR menu where user needs to
enters DMTF to navigate through menu.  When a call originates on MG1 and is
routed to FS1 through SIP.  The DTMF does not get detected by asterisk in
FS1.  To verify this I did 'debug channel' on both servers.  I saw DTMF
frames get detected on MG1 but not on FS1.  The problem started happening
when I upgraded MG1.  So there is something wrong with MG1 sending DTMF
inband.

Updating to latest DAHDI drivers fixes the problem.  I had old Zaptel
drivers installed.  Bug can be closed.
