Hi! Seems calling function KSR.sqlops.sql_num_rows(«sql_res») crashes Kamailio. At least I got this at 5.1.2 from debian repos with LUA. Getting smth like dev1 kernel: [5780693.247255] kamailio[20659]: segfault at 50b300000004 ip 00007f34d2f46fd6 sp 00007ffe1f0ac310 error 4 in sqlops.so[7f34d2f42000+1c000] Regards, Igor

nightly builds
by Aleksandar Sosic 05 Apr '18

Hi everyone, I'm trying the install of the nightly build via apt. In my sources list: deb http://deb.kamailio.org/kamailiodev-nightly xenial main deb-src http://deb.kamailio.org/kamailiodev-nightly xenial main but the apt installs an older version and the upgrade gives: ```kamailio is already the newest version (5.2.0~dev4+0~20180310010216.1064+xenial).``` What am I doing wrong? -- Aleksandar Sosic mail: alex.sosic(a)timenet.it skype: alex.sosic cell: +385 91 2505 146

How to extract SIP-I ISUP parameters
by Eugene Prokopiev 02 Apr '18

02 Apr '18

Hi, I need to extract ISUP parameter 'Redirecting number' from SIP-I INVITE request and add it as SIP header with 'X-' prefix to process in FreeSWITCH. I tried to read https://kamailio.org/docs/modules/5.1.x/modules/sipt.html (but it is about updating headers) and https://kamailio.org/docs/modules/5.1.x/modules/ss7ops.html (but I have only ISUP encapsulated in SIP), so not found any solution. Help me to find it please. -- WBR, Eugene Prokopiev
