The problem with stock libss7 is that one will never complete the tests required from telcos in Europe as it is missing functionality which ITU have described in the test procedures. Without the ISUP timers (the main functionality added from the patches) it is just not possible and the link may

Thanks Kaloyan. Before this thread, there were no mentions at all to a KNK tree, so I though this was stock libss7. I'm using my own patched libss7. I processed over one million call setups with ten servers, with many difficult setups (third party STPs, STPs 1000 miles away with transmission lines

There are no stupid questions, correct. However most of us that started using the internet back when nettiquete was the rule of the land, know that asking questions that have been asked dozens of times before is rude. RTFM was coined a long time ago and Google is your friend is as old as Google's

Hi! So, I'm replying to my own original post, to keep the question and a possible answer together without any excessive or unrelated information. I hope I've found the cause of the problem and I hope I solved it. A modified libss7 is now online and I'm waiting for busy hours to see, whether it

Hello Marcelo, so I did some tracing. It was really hard to isolate MSUs for one particular connection, I had to collect them from about 5 MB file, but ok, it's done, and it's in total harmony with my original ideas. So, let's look at it with me: Initial conditions: There is a call running on LS

Per usual, read the fine manual. Wait, there's no manual ! Since you seem to have done your part and actually knows some ss7 and isup, here comes a hint. You created two or more linksets where you must have a single one. libss7 don't have the ss7 routing feature. In libss7 linkset concept is difer
