[Asterisk-Dev] R2/DTMF on Asterisk? How???

[cziom]

I asked this question on the asterisk-users list and got no assistance 
whatsoever. So I thought this might be a more appropriate forum for the 
inquiry.

If this doesn't generate a response, my next step is to invoke Digium's tech 
support, so feel free to respond now if you're out there Mark. :-)

Thanks,

I just recently purchased an E400P card and am attempting to get it working. 
My requirements are for 2 ports to run Q.931 and the other 2 ports to run R2 
signalling with DTMF inband. The card will operate in a drop and insert 
fashion with calls arriving on the ISDN side and being terminated on the R2 
lines.

There don't seem to be any examples out there of how to set up this card for 
R2 signalling, let alone how to do R2/DTMF. (Yes, I need DTMF not MF or MFC)

Can anyone familiar with Asterisk/Digium give me some advice on how to 
proceed? I'm a fairly competent developer and am not afraid to dig into the 
device driver if my requirements aren't supported, but I'm under alot of 
pressure to get this running quickly, so I'm hoping someone is going to come 
to my rescue.

Can someone point me to any documentation that deals with configuring this 
board for R2? If there isn't any, can anyone tell me where I should look to 
start hacking the code? It's always easier to have a starting point. Failure 
is not an option here, so any advice is appreciated.

Thanks for your assistance,
