How can i do this ? Ooh... Well... the short answer is that you'd have to change the source code. Right now, we have a fixed NAI parameter that is set inside chan_dahdi.conf. You might be able to add a simple dialplan variable to set it though. There are plenty of good examples of doing things like this with other SS7 variables in chan_dahdi.c Matthew Fredrickson Digium, Inc.
