As I got it, there is an ISUP parser inside ss7ops module. It may require a bit of C coding to build a function for helping with what you need -- the two functions that are useful for doing it are:   * https://www.kamailio.org/docs/modules/stable/modules/textops.html#textops.f…   * https://www.kamailio.org/docs/modules/stable/modules/ss7ops.html#ss7ops.f.i… The first one shows how to extract the part of the body from the sip message with the ISUP, the second one shows to convert the ISUP data to json. From there you can use jansson module to extract fields. If you are not familiar with C coding, open a feature request on kamailio issue tracker on github.com, maybe someone can get to it soon, otherwise I will look at it when I get a chance. The other option right now is to use some Python or Lua script to do the parsing of ISUP there, maybe there are libraries for it in those languages. You get get the body of the SIP message inside these messages using $rb variable or the textops function via KSR KEMI module:   - http://kamailio.org/docs/tutorials/devel/kamailio-kemi-framework/kemimods/#…   - http://kamailio.org/docs/tutorials/devel/kamailio-kemi-framework/modules/#k… Cheers, Daniel On 29.03.18 12:50, Eugene Prokopiev wrote: -- Daniel-Constantin Mierla www.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio Advanced Training - April 16-18, 2018, Berlin - www.asipto.com Kamailio World Conference - May 14-16, 2018 - www.kamailioworld.com

Tried to do the same and even less with KEMI/Lua: $ cat kamailio/config/kamailio.lua function ksr_request_route() KSR.info("Lua route\n") if (KSR.textops.has_body("application/isup")) { KSR.info("ISUP body exists\n") } local opv = "" KSR.textops.get_body_part("application/isup", opv) KSR.info("ISUP body content : "..opv.."\n") KSR.sl.send_reply(503, "Server not configured") end I see only endless loop as result: ... kamailio_1 | 12(18) ERROR: <core> [core/io_wait.h:1040]: io_wait_loop_epoll(): epoll_wait(16, 0x7f82df873580, 0, 5000): Invalid argument [22] kamailio_1 | 12(18) ERROR: <core> [core/io_wait.h:1040]: io_wait_loop_epoll(): epoll_wait(16, 0x7f82df873580, 0, 5000): Invalid argument [22] kamailio_1 | 12(18) ERROR: <core> [core/io_wait.h:1040]: io_wait_loop_epoll(): epoll_wait(16, 0x7f82df873580, 0, 5000): Invalid argument [22] ...

I said that this needs C code development to combine parts of get_body_part and isup_to_json. You are trying to do it in config.
