Alright, I see. I just made an ugly hack and applied to my working copy. So far it seems fine. Now my phone does not lose it's PDP context while making a phone call. I'll be working on for some not ugly fix, but all these bits are confusing me haha. Envoyé de mon iPhone Le Aug 5, 2011 à 3:05 PM, Harald Welte <laforge@gnumonks.org> a écrit :

Hi! I tested the patch but the problem still exists :( Here is the new log from sgsn : http://pastebin.com/3PBKQwR5
Then my patch is still wrong. Please look at 24.008 / Section 10.5.7.1 and make sure the code parses the field correctly, i.e. as indicated in the specs.
0x2000 == 0010 0000 0000 0000 corresponding SAPI: 1111 11 7654 3210 5432 1098
i.e. the bit that is set _is_ NSAPI5. This means, the code should _not_ release the PDP context for NSAPI5. But due to erroneous parsing, it _thinks_ that NSAPI5 is not set and it needs to be released.
