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.

I am using ulaw as the codec.  The configuration I have for the sip users
were working perfectly with an older version of Asterisk (1.4.20.1).  Once
I upgraded to latest SVN branch I started to experience this problem.  So I
am almost certain it is not a configuration problem on my end.  

But here is the information you requested: 

Sip user on MG1:

[fs1-mg1]
username=mg1
type=friend
context=pstn
host=*.*.*.*
md5secret=******
dtmfmode=inband
disallow=all
allow=ulaw
nat=yes
qualify=yes


Sip user FS1:


[mg1]
username=fs1-mg1
type=friend
context=default
host=*.*.*.*
md5secret=******
dtmfmode=inband
disallow=all
allow=ulaw
nat=yes
qualify=yes
