Hi,
Yes, the DTMF digits detected are the correct caller id. This line is in India from a telco called Airtel. I think caller id is being sent via DTMF. Based on what I've read on various forums, from people trying to get it to work on sipura devices or dahdi with asterisk, Airtel uses polarity reversal to first alert the other end to pick up caller id and then sends it via DTMF. I'll try and confirm this soon.
Ok, so this is a good opportunity for us to add support for DTMF caller id. If you can give me ssh to your box I can log in to code and test this feature.
