Hello! I'm testing call recording with Rtpengine. It works fine when the "record-call=on" flag is added to the *rtpengine_offer* or *start_recording* is used in the *request_route*. But I was wondering if the call recording can be managed by a separate application. So I add the following lines to the *event_route[xhttp:request]* and triggered it with an HTTP request after the call was established. The call-id value was taken from the Rtpengine log and sent with the request. * if ($hu =~ "^/CALL_RECORD_START/") {* * $var(call_id) = *"call-id=" + *$(hu{s.select,2,/});* xlog("L_DBG", "$var(call_id)"); * start_recording($var(call_id));* exit; * }* In this case, Kamailio will log errors and will not send the Rtpengine command to start call recording. *Apr 27 18:25:00 test /usr/sbin/kamailio[5347]: DEBUG: <script>: call-id=3de74068278ede4417086eb82bdf5a06@127.0.0.1:5080.0* *Apr 27 18:25:00 test /usr/sbin/kamailio[5347]: DEBUG: <core> [core/parser/msg_parser.c:89]: get_hdr_field(): found end of header* *Apr 27 18:25:00 test /usr/sbin/kamailio[5347]: ERROR: rtpengine [rtpengine_funcs.c:294]: get_callid(): call-id not found* *Apr 27 18:25:00 test /usr/sbin/kamailio[5347]: ERROR: rtpengine [rtpengine.c:2383]: rtpp_function_call(): can't get Call-Id field* Have anyone tried to call functions *start_recording* and *stop_recording* inside *event_route[xhttp:request]*? Thanks a lot!

I run Kamailio with debug=3 and Rtpengine with LOG_LEVEL=6. Rtpengine logs offers, answers and deletes but there is nothing when I trigger *start_recording* with HTTP request. Below is the full Kamailio log for the request. It looks to be failing right on the *start_recording* function and I don't see any other issues except empty Call-Id here: "receive_msg(): --- received sip message - request - call-id: [] - cseq: []". I tried to add Call-Id header to my HTTP request and found out that now rtpengine module will complain about missing To header. With tries and errors, I specified all required headers and Rtpengine started call recording: */usr/bin/curl -H "Content-Type: text" "http://localhost:8088/CALL_RECORD_START/38687ab466a031d20d852706710d2b4f@127.0.0.1:5080.1 <http://localhost:8088/CALL_RECORD_START/38687ab466a031d20d852706710d2b4f@127.0.0.1:5080.1>" -H "Call-Id: 38687ab466a031d20d852706710d2b4f@127.0.0.1:5080.1" -H "To: sip:200-test@127.0.0.1:5060 <http://sip:200-test@127.0.0.1:5060>" -H "From: <sip:2564286000@127.0.0.1:5080 <http://sip:2564286000@127.0.0.1:5080>>;tag=as7a92114c"* It also looks like rtpengine module does not care about actual header values. Function *start_recording* called with Call-Id value is enough to start call recording even if all headers contain random invalid values: * /usr/bin/curl -H "Content-Type: text" "http://localhost:8088/CALL_RECORD_START/6559572e21e08e0a41503ba5779c6604@127.0.0.1:5080.0 <http://localhost:8088/CALL_RECORD_START/6559572e21e08e0a41503ba5779c6604@127.0.0.1:5080.0>" -H "Call-Id: does_mot_matter" -H "To: sip:456@127.0.0.1:5060 <http://sip:456@127.0.0.1:5060>" -H "From: <sip:123@127.0.0.1:5080 <http://sip:123@127.0.0.1:5080>>;tag=1"* *Thank you very much for your help!* *Apr 29 16:01:47 test /usr/sbin/kamailio[24120]: DEBUG: <core> [core/ip_addr.c:229]: print_ip(): tcpconn_new: new tcp connection: 127.0.0.1* *Apr 29 16:01:47 test /usr/sbin/kamailio[24120]: DEBUG: <core> [core/tcp_main.c:1175]: tcpconn_new(): on port 42782, type 2, socket 64* *Apr 29 16:01:47 test /usr/sbin/kamailio[24120]: DEBUG: <core> [core/tcp_main.c:1498]: tcpconn_add(): hashes: 1710:1616:2551, 1* *Apr 29 16:01:47 test /usr/sbin/kamailio[24120]: DEBUG: <core> [core/io_wait.h:375]: io_watch_add(): DBG: io_watch_add(0xae63a0, 64, 2, 0x7f943ba04ac0), fd_no=50* *Apr 29 16:01:47 test /usr/sbin/kamailio[24120]: DEBUG: <core> [core/io_wait.h:600]: io_watch_del(): DBG: io_watch_del (0xae63a0, 64, -1, 0x0) fd_no=51 called* *Apr 29 16:01:47 test /usr/sbin/kamailio[24120]: DEBUG: <core> [core/tcp_main.c:4457]: handle_tcpconn_ev(): sending to child, events 1* *Apr 29 16:01:47 test /usr/sbin/kamailio[24120]: DEBUG: <core> [core/tcp_main.c:4130]: send2child(): selected tcp worker idx:0 proc:35 pid:24116 for activity on [tcp:127.0.0.1:8088 <http://127.0.0.1:8088>], 0x7f943ba04ac0* *Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/tcp_read.c:1749]: handle_io(): received n=8 con=0x7f943ba04ac0, fd=13* *Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:610]: parse_msg(): SIP Request:* *Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:612]: parse_msg(): method: <GET>* *Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:614]: parse_msg(): uri: </CALL_RECORD_START/7a444c165953cf0a196e10e50d0b611e@127.0.0.1:5080.0>* *Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:616]: parse_msg(): version: <HTTP/1.1>* *Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:89]: get_hdr_field(): found end of header* *Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/receive.c:324]: receive_msg(): --- received sip message - request - call-id: [] - cseq: []* *Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: xhttp [xhttp_mod.c:382]: xhttp_handler(): new fake msg created (286 bytes):* *Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:610]: parse_msg(): SIP Request:* *Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:612]: parse_msg(): method: <GET>* *Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:614]: parse_msg(): uri: </CALL_RECORD_START/7a444c165953cf0a196e10e50d0b611e@127.0.0.1:5080.0>* *Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:616]: parse_msg(): version: <HTTP/1.1>* *Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/parse_via.c:2639]: parse_via(): end of header reached, state=5* *Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:498]: parse_headers(): Via found, flags=2* *Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:500]: parse_headers(): this is the first via* *Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <script>: == TRACE. xhttp:request* *Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <script>: == TRACE. xhttp:request.

Ohhh, blindly missed the assignment before. You should run both kamailio and rtpengine with higher debug level and see if you get any hints from the log messages.

I looked in the code and indeed it first takes the values from headers for Call-Id, To (tag), From (tag), failing if the headers are not found, but then it updates the values from the flags parameter. So the call-id can be anything in the headers if you provide it as "call-id=xyz" parameter. Maybe the code should be reworked a bit to parse first the flags parameters and if values are not found for the sip attributes, then try to get them from headers.

Hello Daniel, Sorry, I was out of the office and could make a test only now. As you told, the HTTP request is now processed differently. Unfortunately, I can no longer start call recording. I tried the following options and got the "rtpp_function_call(): can't get From tag" error message each time. 1. /usr/bin/curl -H "Content-Type: text" " http://localhost:8088/CALL_RECORD_START/249ae6300da4b1393be203e21068f6a2@12… " 2. /usr/bin/curl -H "Content-Type: text" " http://localhost:8088/CALL_RECORD_START/249ae6300da4b1393be203e21068f6a2@12… -H "From: <sip:123@127.0.0.1:5080>;tag=1" 3. /usr/bin/curl -H "Content-Type: text" " http://localhost:8088/CALL_RECORD_START/249ae6300da4b1393be203e21068f6a2@12… -H "Call-Id: 249ae6300da4b1393be203e21068f6a2@127.0.0.1:5080.0" -H "To: sip:456@127.0.0.1:5060" -H "From: <sip:123@127.0.0.1:5080>;tag=1" *May 5 14:40:43 test /usr/sbin/kamailio[19603]: DEBUG: <core> [core/parser/parse_fline.c:250]: parse_first_line(): first line type 1 (request) flags 2* *May 5 14:40:43 test /usr/sbin/kamailio[19603]: DEBUG: <core> [core/parser/msg_parser.c:677]: parse_msg(): SIP Request:* *May 5 14:40:43 test /usr/sbin/kamailio[19603]: DEBUG: <core> [core/parser/msg_parser.c:679]: parse_msg(): method: <GET>* *May 5 14:40:43 test /usr/sbin/kamailio[19603]: DEBUG: <core> [core/parser/msg_parser.c:681]: parse_msg(): uri: </CALL_RECORD_START/249ae6300da4b1393be203e21068f6a2@127.0.0.1:5080.0>* *May 5 14:40:43 test /usr/sbin/kamailio[19603]: DEBUG: <core> [core/parser/msg_parser.c:683]: parse_msg(): version: <HTTP/1.1>* *May 5 14:40:43 test /usr/sbin/kamailio[19603]: DEBUG: <core> [core/parser/parse_hname2.c:294]: parse_sip_header_name(): parsed header name [Via] type 1* *May 5 14:40:43 test /usr/sbin/kamailio[19603]: DEBUG: <core> [core/parser/parse_via.c:2639]: parse_via(): end of header reached, state=5* *May 5 14:40:43 test /usr/sbin/kamailio[19603]: DEBUG: <core> [core/parser/msg_parser.c:555]: parse_headers(): Via found, flags=2* *May 5 14:40:43 test /usr/sbin/kamailio[19603]: DEBUG: <core> [core/parser/msg_parser.c:557]: parse_headers(): this is the first via* *May 5 14:40:43 test /usr/sbin/kamailio[19603]: DEBUG: <script>: == TRACE. xhttp:request* *May 5 14:40:43 test /usr/sbin/kamailio[19603]: DEBUG: <script>: == TRACE. xhttp:request.

I pushed a commit to master branch that should make it work to use the function for non-SIP message processing, by giving call-id=... and from-tag=... via flags parameter -- these two attributes seemed to be used by expecting to be set, even if the rtpengine application may ignore one of them. If you have a chance to test, let me know the result. Cheers, Daniel On 29.04.21 16:38, Daniel-Constantin Mierla wrote: I looked in the code and indeed it first takes the values from headers for Call-Id, To (tag), From (tag), failing if the headers are not found, but then it updates the values from the flags parameter. So the call-id can be anything in the headers if you provide it as "call-id=xyz" parameter. Maybe the code should be reworked a bit to parse first the flags parameters and if values are not found for the sip attributes, then try to get them from headers.

Rtpengine logs offers, answers and deletes but there is nothing when I trigger *start_recording* with HTTP request. Below is the full Kamailio log for the request. It looks to be failing right on the *start_recording* function and I don't see any other issues except empty Call-Id here: "receive_msg(): --- received sip message - request - call-id: [] - cseq: []". I tried to add Call-Id header to my HTTP request and found out that now rtpengine module will complain about missing To header.

Hello, ok, good that it works now. You should still be able to take them from headers with $ci and $ft, but they have to be provided in the parameter of start_recording()/stop_recording() if used with a non-SIP message. Cheers, Daniel On 05.05.21 18:20, Володимир Іванець wrote:

Function /start_recording/ called with Call-Id value is enough to start call recording even if all headers contain random invalid values: / /usr/bin/curl -H "Content-Type: text" "http://localhost:8088/CALL_RECORD_START/6559572e21e08e0a41503ba5779c6604@127.0.0.1:5080.0 <http://localhost:8088/CALL_RECORD_START/6559572e21e08e0a41503ba5779c6604@127.0.0.1:5080.0>" -H "Call-Id: does_mot_matter" -H "To: sip:456@127.0.0.1:5060 <http://sip:456@127.0.0.1:5060>" -H "From: <sip:123@127.0.0.1:5080 <http://sip:123@127.0.0.1:5080>>;tag=1"/ *Thank you very much for your help!* /Apr 29 16:01:47 test /usr/sbin/kamailio[24120]: DEBUG: <core> [core/ip_addr.c:229]: print_ip(): tcpconn_new: new tcp connection: 127.0.0.1/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24120]: DEBUG: <core> [core/tcp_main.c:1175]: tcpconn_new(): on port 42782, type 2, socket 64/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24120]: DEBUG: <core> [core/tcp_main.c:1498]: tcpconn_add(): hashes: 1710:1616:2551, 1/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24120]: DEBUG: <core> [core/io_wait.h:375]: io_watch_add(): DBG: io_watch_add(0xae63a0, 64, 2, 0x7f943ba04ac0), fd_no=50/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24120]: DEBUG: <core> [core/io_wait.h:600]: io_watch_del(): DBG: io_watch_del (0xae63a0, 64, -1, 0x0) fd_no=51 called/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24120]: DEBUG: <core> [core/tcp_main.c:4457]: handle_tcpconn_ev(): sending to child, events 1/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24120]: DEBUG: <core> [core/tcp_main.c:4130]: send2child(): selected tcp worker idx:0 proc:35 pid:24116 for activity on [tcp:127.0.0.1:8088 <http://127.0.0.1:8088>], 0x7f943ba04ac0/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/tcp_read.c:1749]: handle_io(): received n=8 con=0x7f943ba04ac0, fd=13/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:610]: parse_msg(): SIP Request:/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:612]: parse_msg(): method: <GET>/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:614]: parse_msg(): uri: </CALL_RECORD_START/7a444c165953cf0a196e10e50d0b611e@127.0.0.1:5080.0> <mailto:/CALL_RECORD_START/7a444c165953cf0a196e10e50d0b611e@127.0.0.1:5080.0>/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:616]: parse_msg(): version: <HTTP/1.1>/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:89]: get_hdr_field(): found end of header/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/receive.c:324]: receive_msg(): --- received sip message - request - call-id: [] - cseq: []/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: xhttp [xhttp_mod.c:382]: xhttp_handler(): new fake msg created (286 bytes):/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:610]: parse_msg(): SIP Request:/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:612]: parse_msg(): method: <GET>/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:614]: parse_msg(): uri: </CALL_RECORD_START/7a444c165953cf0a196e10e50d0b611e@127.0.0.1:5080.0> <mailto:/CALL_RECORD_START/7a444c165953cf0a196e10e50d0b611e@127.0.0.1:5080.0>/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:616]: parse_msg(): version: <HTTP/1.1>/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/parse_via.c:2639]: parse_via(): end of header reached, state=5/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:498]: parse_headers(): Via found, flags=2/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <core> [core/parser/msg_parser.c:500]: parse_headers(): this is the first via/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <script>: == TRACE. xhttp:request/ /Apr 29 16:01:47 test /usr/sbin/kamailio[24116]: DEBUG: <script>: == TRACE. xhttp:request.
