Hi, I can imagine that the problems come from the configuration within the docker container. IP address and ports are somehow automatically defined and I'm not sure if these paramerts are correct. And I can not enter the routing scripts for HOMER intergration in the docker container. Therefore , I want to install and run kamailio with rtpengine directly outside a docker container on my debian vm. But I'm pretty much confused by the default kamailio configuration file with all the parameters, directives and loadmodules. Can somebody send me a basic configuration file for *kamailio with websockets, TLS Support and rtpengine. * Thanks and regards Peter Am 07.08.25 um 19:24 schrieb Richard Robson via sr-users: > > Hi, > > You could run up a Homer server and send the traffic to there from > Kamailio with the sipcapture module.
