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" "

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

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.

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

-H "Call-Id: 38687ab466a031d20d852706710d2b4f@127.0.0.1:5080.1

<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

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.

Hello,
related to the initial config snippet example, the call-id is expected
to be provide as a named flag, like:
start_recording("call-id=$var(call_id)");
See the readme of the rtpengine module for more details.
Cheers,
Daniel

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;
* }*
If you have to reason to go through Kamailio for this, you can simply
trigger the command from any other external application. There's a sample
script included in the repo that can be used for this purpose directly
(making use of the Perl module that is also included):
https://github.com/sipwise/rtpengine/blob/master/utils/rtpengine-ng-client
There's also a nodejs client that I'm aware of:
https://github.com/davehorton/rtpengine-client
Or you can hand-roll the request and talk to rtpengine via HTTP or
Websocket for example.
Cheers
