Is this idea even feasible?
by Antony Stone 04 Nov '21

Hi. I'm looking for a solution to the following problem, and wondering whether Kamailio (with which I have very little experience so far) may be it, or whether I'm thinking in totally the wrong direction. The problem: I have a SIP client application which runs on a standard Linux system, and is extremely basic - it can REGISTER in order to receive inbound calls, and it can send INVITEs in order to place outbound calls, and that's about it. It handles media as well - in essence, it's a simple softphone. I can't change it for a more capable one, before anyone suggests that :) Specifically, this thing cannot send REINVITEs in order to put calls on hold, nor can it handle anything to do with transfers (blind or attended). I'm looking for something which does have these SIP capabilities which I could put in between this application and the SIP server through which it is placing and receiving calls, so that I can (through some sort of API) cause calls in progress to be put on hold, resumed, blind transferred, or hold-and-attended- transferred. Does that sound like something Kamailio can do? If so, can anyone point me in a helpful direction re how to go about it? If not, can anyone suggest something else which could sit in between a very basic SIP client and a PBX server, in order to inject these sorts of commands into the path and thereby give me these sorts of extra call capabilities? Thanks, Antony. -- I'm not impossible, just highly implausible. Please reply to the list; please *don't* CC me.

STIR/SHAKEN, is a number format mandatory?
by David Villasmil 04 Nov '21

Hello guys, I'm getting failed by my provider because I'm sending to them with +1 both on the headers and on the payload. My understanding is there is no mandatory format, or is there? Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

UAC reg_random_delay
by Sergiu Pojoga 03 Nov '21

Hi there, May I know what exactly is supposed to be "delayed" in the UAC registration? *modparam("uac", "reg_random_delay", 20)* I have records stored in DB with *reg_delay=0*. When doing *uac.reg_dump*, I do see the value of *reg_delay* being random for various records. However, after restarting Kamailio, the registrations are all sent out *simultaneously*, there doesn't seem to be a "delay", whatever the purpose is supposed to be. Can someone clarify please? Kamailio 5.5.0 Thanks. Regards, --Sergiu

how to prevent the log_prefix in syslog acc cdrs?
by Karsten Horsmann 02 Nov '21

02 Nov '21

Hi List, i thought there could be a solution to disable the log_prefix for acc module - but i didn't found it. Is there a solution to supress log_prefix for acc like acc_json did that? I use kamailio 5.5.2 with that settings: log_name="kamailio" log_facility=LOG_LOCAL4 log_prefix="{$hdr(CSeq) $ci} " the acc module then logs the "log_prefix" - plus some module/function stuff: INFO: {1 INVITE SDkk50d01-1f7cc956b0b908e42d284189a11b44e7-ct46om0050} acc [acc.c:285]: acc_log_request(): ACC: transaction answered: timestamp=1635843776;utctime=2021-11-02 09:02:56;method=INVITE;from_tag=SDkk50d01-e8bc0cda;to_tag=XBr6apQ9HN4HD;call_id=SDkk50d01-1f7cc956b0b908e42d284189a11b44e7-ct46om0050;code=200;reason=OK;src_user=bob;src_domain=sip100;src_ip=172.20.120.56;dst_ouser=alice;dst_user=echo;dst_domain=172.20.120.59;user_agent=;x_t_call_id=;x_routing=;x_billing= INFO: {1 ACK SDkk50d01-1f7cc956b0b908e42d284189a11b44e7-ct46om0050} acc [acc.c:285]: acc_log_request(): ACC: request acknowledged: timestamp=1635843776;utctime=2021-11-02 09:02:56;method=ACK;from_tag=SDkk50d01-e8bc0cda;to_tag=XBr6apQ9HN4HD;call_id=SDkk50d01-1f7cc956b0b908e42d284189a11b44e7-ct46om0050;code=200;reason=OK;src_user=bob;src_domain=sip100;src_ip=172.20.120.56;dst_ouser=alice;dst_user=alice;dst_domain=172.20.120.51;user_agent=;x_t_call_id=;x_routing=;x_billing= INFO: {2 BYE SDkk50d01-1f7cc956b0b908e42d284189a11b44e7-ct46om0050} acc [acc.c:285]: acc_log_request(): ACC: transaction answered: timestamp=1635843833;utctime=2021-11-02 09:03:53;method=BYE;from_tag=SDkk50d01-e8bc0cda;to_tag=XBr6apQ9HN4HD;call_id=SDkk50d01-1f7cc956b0b908e42d284189a11b44e7-ct46om0050;code=200;reason=OK;src_user=bob;src_domain=sip100;src_ip=172.20.120.56;dst_ouser=alice;dst_user=alice;dst_domain=172.20.120.51;user_agent=;x_t_call_id=;x_routing=;x_billing= The acc_json module is able to log acc without log_prefix: {"time": "2021/11/02 10:02:56", "method": "INVITE", "from_tag": "SDkk50d01-e8bc0cda", "to_tag": "XBr6apQ9HN4HD", "callid": "SDkk50d01-1f7cc956b0b908e42d284189a11b44e7-ct46om0050", "sip_code": "200", "sip_reason": "OK", "src_user": "bob", "src_domain": "sip100", "src_ip": "172.20.120.56", "dst_ouser": "alice", "dst_user": "echo", "dst_domain": "172.20.120.59", "user_agent": "", "x_t_call_id": "", "x_routing": "", "x_billing": ""} {"time": "2021/11/02 10:03:53", "method": "BYE", "from_tag": "SDkk50d01-e8bc0cda", "to_tag": "XBr6apQ9HN4HD", "callid": "SDkk50d01-1f7cc956b0b908e42d284189a11b44e7-ct46om0050", "sip_code": "200", "sip_reason": "OK", "src_user": "bob", "src_domain": "sip100", "src_ip": "172.20.120.56", "dst_ouser": "alice", "dst_user": "alice", "dst_domain": "172.20.120.51", "user_agent": "", "x_t_call_id": "", "x_routing": "", "x_billing": ""} And just for the records - how to get rid off the rsyslog prefix time/date stuff: # /etc/rsyslog.d/kamailio.conf # drop :msg from rtpengine with "timer run time" - debugging only: :msg, contains, "timer run time" ~ # Template only msg: $template myFormat,"%msg%\n" # log only to local* and NOT to /var/log/messages local6.*;local6.!=info -/var/log/platform/voip/kamailio/rtpengine.log local6.* stop local5.* -/var/log/platform/voip/kamailio/rtpengine-cdr.log; myFormat local5.* stop local4.* -/var/log/platform/voip/kamailio/kamailio.log local4.* stop local2.* -/var/log/platform/voip/kamailio/kamailio-cdr.log; myFormat local2.* stop local1.* -/var/log/platform/voip/kamailio/kamailio-cdr-json.log; myFormat local1.* stop -- Mit freundlichen Grüßen *Karsten Horsmann*

kamailio didnt run with acc_json (without dialog module) - kamailio 5.5.2

Hi List, i want to try out acc_json (to syslog). But if i set up "cdr_enable", 1 - it breaks the startup of kamailio with that error (dialog module is not listed as dependency). Any hints?
