I am compiling the kamailio 4.3 in raspberry Pi 2. It compiled and worked. However, kamcmd did not work as it looks for the file /var/run/kamailio/kamailio.ctl which is not present. Similar issue found for kamctl but I fixed it by change the /tmp directory to /var/run/kamailio Did I miss something?

Hi, I am trying to change only the "display name" of the FROM header using uac_replace_from().However, the value is not being changed (see below) request_route { .... xlog ("L_INFO", "fu=$fu"); uac_replace_from("pbx", ""); xlog ("L_INFO", "fu=$fu"); # authentication route(AUTH); ....} Am I missing anything? Any help in this regard would be greatly appreciated. Thanks,Al

Re: [SR-Users] loose_route to find transport=tcp

After enabling and deciphering debugging it appears there may be a bug. I also reviewed https://tools.ietf.org/html/rfc5658#section-6 I cross-referenced my pcap to ensure I was looking at the reINVITE and see: Jun 16 15:01:29 xxxxxxxxxxxxx /usr/sbin/kamailio[643]: DEBUG: rr [loose.c:785]: after_loose(): *Topmost route URI: 'sip:xx.xxx.x.xx;lr;r2=on;ftag=a30a720a;did=b75.65a1;nat=yes' is me* Jun 16 15:01:29 xxxxxxxxxxxxx /usr/sbin/kamailio[643]: DEBUG: <core> [socket_info.c:583]: grep_sock_info(): grep_sock_info - checking if host==us: 11==11 && [xx.xxx.x.xx] == [xx.xxx.x.xx] Jun 16 15:01:29 xxxxxxxxxxxxx /usr/sbin/kamailio[643]: DEBUG: <core> [socket_info.c:587]: grep_sock_info(): grep_sock_info - checking if port 5060 (advertise 0) matches port 5061 Jun 16 15:01:29 xxxxxxxxxxxxx /usr/sbin/kamailio[643]: DEBUG: <core> [socket_info.c:583]: grep_sock_info(): grep_sock_info - checking if host==us: 11==11 && [xx.xxx.x.xx] == [xx.xxx.x.xx] Jun 16 15:01:29 xxxxxxxxxxxxx /usr/sbin/kamailio[643]: DEBUG: <core> [socket_info.c:587]: grep_sock_info(): grep_sock_info - checking if port 5070 (advertise 0) matches port 5061 Jun 16 15:01:29 xxxxxxxxxxxxx /usr/sbin/kamailio[643]: DEBUG: <core> [socket_info.c:583]: grep_sock_info(): grep_sock_info - checking if host==us: 11==11 && [xx.xxx.x.xx] == [xx.xxx.x.xx] Jun 16 15:01:29 xxxxxxxxxxxxx /usr/sbin/kamailio[643]: DEBUG: <core> [socket_info.c:587]: grep_sock_info(): grep_sock_info - checking if port 5090 (advertise 0) matches port 5061 Jun 16 15:01:29 xxxxxxxxxxxxx /usr/sbin/kamailio[643]: DEBUG: <core> [socket_info.c:583]: grep_sock_info(): grep_sock_info - checking if host==us: 11==11 && [xx.xxx.x.xx] == [xx.xxx.x.xx] Jun 16 15:01:29 xxxxxxxxxxxxx /usr/sbin/kamailio[643]: DEBUG: <core> [socket_info.c:587]: grep_sock_info(): grep_sock_info - checking if port 5061 (advertise 0) matches port 5061 Jun 16 15:01:29 xxxxxxxxxxxxx /usr/sbin/kamailio[643]: DEBUG: <core> [parser/msg_parser.c:106]: get_hdr_field(): found end of header Jun 16 15:01:29 xxxxxxxxxxxxx /usr/sbin/kamailio[643]: DEBUG: rr [loose.c:181]: find_next_route(): *No next Route HF found* Jun 16 15:01:29 xxxxxxxxxxxxx /usr/sbin/kamailio[643]: DEBUG: rr [loose.c:847]: after_loose(): no next URI found There is definitely another Route header immediately below the one found above, but find_next_route() doesn't find it .

We have done very little work in the Kamailio source...just some database escaping in odbc for things to work properly with our database engine...but unless I'm missing something isn't it very wrong to be looking at the last header right here? I may attempt to figure out the message and/or hdr_field data structures and change it. It may also be that the issue doesn't occur when find_next_route is called with a valid _hdr which does seem to search for the "next" one vs going straight to the final header in the entire message. If this is getting overly complicated for this mailing list please let me know...

siptrace: how to log sent ACK within dialog
by Seudin Kasumovic 17 Jun '15

17 Jun '15

Hi, TM forward ACK statelessly (see log below), so there is no call of installed callback on TMCB_REQUEST_(IN)SENT in siptrace module, so I can't see way how to log ACK sent packet. Any work around to get sent ACK logged? DEBUG: sl [sl_funcs.c:388]: sl_filter_ACK(): DEBUG : sl_filter_ACK: to late to be a local ACK!

http_query failed to perform curl (28) errors
by Armen Babikyan 17 Jun '15

17 Jun '15

Hello, I am running across the same issue as described here: http://lists.sip-router.org/pipermail/sr-users/2015-February/086796.html Was there a resolution to this issue? I come across this issue fairly regularly. Unlike the OP, however, I do not have any luck by retrying my query: when I place my http_query within a while loop and keep 1-second delays between calls, all consistently fail with error 28. After long pauses, http_query()s start to work as expected. I think that previous thread mentions DNS as a possible culprit. Is http_query using libcurl's preferred resolver, or is it using Kamailio's built-in DNS cache? I really doubt my local resolver is cause of the issue here. Any insight is appreciated. Thanks! Armen
