recording audio stream
by bill＠telopar.net 18 Nov '18

18 Nov '18

Hi All: I have a project that requires that I record the audio streams from an ongoing phone call. It seems that rtp_proxy module should do that, but I can't seem to get it to work. My config file: *if(nat_uac_test("8")) { //rtpproxy_manage("co"); xlog("L_INFO", "rtpproxy Call is going to private IPv4 Media Server Engage RTPProxy Now\n"); rtpproxy_manage("crwie","10.1.1.2"); } else { //rtpproxy_manage("cor"); xlog("L_INFO", "rtpproxy Call is coming from a private IPv4 Media Server Engage RTPProxy Now\n"); rtpproxy_manage("crwei","10.1.1.2"); } *There appears to be conversations going on with rtpproxy on both legs of the call. But I seem to be missing the step that records the audio*. *Anybody have an example of how to do this. TIA, Bill **

Which algorithm to use as load-balance
by David Villasmil 16 Nov '18

16 Nov '18

Hello, Is it possible to set an algorithm like the following? fs1 - Priority 10 - maxload 20 calls fs2 - Priority 10 - maxload 20 calls fs3 - Priority 9 - maxload 20 calls fs4 - Priority 8 - maxload 20 calls fs5 - Priority 7 - maxload 20 calls So that, whenever any new call comes in, fs1 and fs2 would be used, meaning the fs with the highest priority would be use UNLESS there's 20 calls on that server, in which case, the next server with the highest priority would be used. Thanks!, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337 ᐧ

priority load balance
by David Villasmil 15 Nov '18

15 Nov '18

Hello, Trying to do priority load balancing (8) but i'm getting an error `unable to update destination load - classic dispatching` anyone knows why? i've got ```modparam("dispatcher", "db_url", DBURL) modparam("dispatcher", "table_name", "dispatcher") modparam("dispatcher", "flags", 2) modparam("dispatcher", "dst_avp", "$avp(AVP_DST)") modparam("dispatcher", "grp_avp", "$avp(AVP_GRP)") modparam("dispatcher", "cnt_avp", "$avp(AVP_CNT)") modparam("dispatcher", "dstid_avp", "$avp(dsdstid)") modparam("dispatcher", "attrs_avp", "$avp(dsattrs)")``` Looking at the code, dstid_avp would be null, but not sure why? I have set in the table the priorities as 10 for 2 gws (edited) Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337 ᐧ

Hi, we are using kamailio 5.1 with siptrace module in trace_mode on. Everything works perfect except that option pings from nathelper module do not get duplicated. Is there a reason for that? Thanks, Roman

Core dump on diameter CCR request

Hi all, I am trying to implement Diameter charging with Kamailio. I am following below tutorial https://www.kamailio.org/events/2016-KamailioWorld/Day2/15-Carsten.Bock-Dia… But whenever I try to do the Ro_CCR from the INVITE block, Kamailio is crashing and generating the core dump. I am new to diameter. I might be doing something wrong here. please someone help me here.
