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.

On the face of it, it would appear that you are either suffering from codec issues and not an Asterisk issue. In any case, I would suggest that you bring this issue up with the asterisk-users mailing list, as this appears to be more of an operational/configuration issue, than an Asterisk bug. Nir By: Remi Quezada (remiq) 2009-01-21 15:13:44.000-0600 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 By: Remi Quezada (remiq) 2009-01-27 12:47:32.000-0600 Updating to latest DAHDI drivers fixes the problem.  I had old Zaptel drivers installed.  Bug can be closed.
