Hello, I'm trying to implement missing COT functionality in libss7. As I can see, actually libss7 can only reply on COT requests, but cannot initiate a COT procedure itself. Do anyone has tried to do that before? Do you think that the function ast_playtones_start could work in chan_dahdi.c? And how would you do tone detection (looped back from the other side)? Many thanks for your suggestions! mario -------------- next part -------------- An HTML attachment was scrubbed...
