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

[Vinod Sankar]

AFAIK Digium E1 cards do not support R2 or CAS, only ISDN PRI. I had received
a mail to this effect sometime back from Digium sales.

- 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

- 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.
