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? Failure is not an option here, so any advice is appreciated. Thanks for your assistance, Chris Ziomkowski cziom@jsg.co.th
