asterisk users - Dec 2009 - ISDN: Inband DTMF doesn't trigger transfer feature

Hi there,

I just upgraded a relatively old Asterisk installation (1.2) in our 
office to a relatively new version (1.6svn from last wednesday) which 
runs a Junghans QuadBRI card [1].

To get this flying I got dahdi-linux, dahdi-tools and libpri from SVN as 
well.

After a while of juggling it "works".

What doesn't work: connected ISDN devices (Gigaset phones connected to 
QuadBRI with a port in NT mode, signalling via bri_net_ptmp) can not 
transfer calls by pressing "#". SIP phones can.

I'm at a point where I can't even get *any* output to debug. I went 
through the relevant configs as good as I can a couple of times but am 
out of ideas. I'm guessing that this is somehow related to either 
Asterisk not being able to monitor the call for inband DTMF (which I can 
prove how?) or something in the relatively new bri_net_ptmp code that 
breaks it (which I can't prove either).

A pointer how to debug this further would be very appreciated.

Best regards,
Christian

I would be very pleased to be corrected but I don't think NT/ptmp mode is
supported now (I think this is an ongoing work but it's not complete)
through Dahdi.
