Selectively enable / disable cdrs using acc module
by M S 23 Jul '18

23 Jul '18

Hi, I have a kamailio v5.0 setup where cdrs are enabled using acc module. Is there a way to enable / disable cdrs on per call basis in kamailio script? For example i want to allow cdrs only for offnet calls and disable them for onnet calls? May be a dialog flag configurable in module parameters to signal acc module whether or not to generate cdr for current dialog at the end of call?

dialog module with dmq
by E. Schmidbauer 22 Jul '18

Is anyone using dialog module with DMQ to share dialogs across multiple kamailio instances? i've been testing it and it seems unreliable. sometimes the dialog data is sent from nodeA to nodeB, sometimes it is not. im wondering if im missing some settings or it's a bug. I tested latest master branch and version 5.1.4 Thanks! Emmanuel

$var(name) - Private memory variables
by Sergey Safarov 21 Jul '18

21 Jul '18

Hello I have faced when case when private var defined as $var(json_request) is share between different SIP messages. In my case first time this var is used from registration processing route. Then var with same name is used PUBLISH messge processing. And i be able to this value defined from registration processing. I expecting that vars is not shared between threads and message handling routes for var defined as $var(name). Is that not true? How i can prevent race condition between different message processing routes when two thread simultaneously change same variable? Sergey

The problem of get_aor_hash function
by tyd 20 Jul '18

20 Jul '18

Dear all, I'm trying Kamailio 5.1.4 and IMS module. When registering to Kamailio IMS using the same ip and port for 30 users (different contact user part), the P-CSCF get the same hash number and aor value. The function get_aor_hash(_d, &_ci->via_host, _ci->via_port, _ci->via_prot) in ims_usrloc_pcscf pcontact.c seems the problem. Because hashing with host, port, prot will get the same hash value. Anyone can help this ?
