NatHelper ignoring force_socket module parameter
by Asgaroth 24 Oct '17

24 Oct '17

Hi All, I have a strange issue, I have set the module parameter for nathelper's force_socket to a specfic ip/port, however, when I perform a sip trace I can see that all locally generated options messages are not sent from the socket defined in the modules parameters. I am not setting $fs anywhere in the script, so I am not over-writing it. Do any of the other module parameters have a bearing on if nathelper uses the force_socket parameter? My current nathelper settings are: modparam("nathelper", "received_avp", "$avp(RECEIVED)") modparam("nathelper", "natping_interval", 20) modparam("nathelper", "natping_processes", 4) modparam("nathelper", "ping_nated_only", 1) modparam("nathelper", "sipping_from", "sip:keepalive@domain.com") modparam("nathelper", "sipping_method", "OPTIONS") modparam("nathelper", "sipping_bflag", NAT_BFLAG) modparam("nathelper", "force_socket", "1.2.3.4:5060") I am using kamailio v4.3.1: # kamailio -V version: kamailio 4.3.1 (x86_64/linux) f38e67 flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, F_MALLOC, DBG_F_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: f38e67 compiled on 18:15:23 Jul 20 2015 with gcc 4.4.7 Thanks

Kamailio 4.3.4: receive_msg(): no via found in reply
by Grant Bagdasarian 15 Aug '17

15 Aug '17

Hello, We're testing kamailio 4.3.4 with two kamailio's communicating with each other. One of them is a gateway with rtpengine at the carrier side, the other is a basic sip router. When calling a destination and cancelling the INVITE a 487 is received from the carrier and directly ACK'd by the first kamailio and in turn is forwarded to the second. But the 487 response received by the 2nd kamailio doesn't have a Via header which results in kamailio printing the error: receive_msg(): no via found in reply. Any ideas why the forwarded 487 doesn't contain a Via header and how to fix this? Note: IP's are changed. Carrier: 10.0.0.1 Kamailio 1: 10.14.0.1 Kamailio 2: 10.14.0.2 U 10.0.0.1:5060 -> 10.14.0.1:5060 SIP/2.0 487 Request Cancelled.

Core crash in del_lump() "offset exceeds message size" when using subst() inside tm:local-request route.
by Cody Herzog 08 Aug '17

08 Aug '17

Hello. Inside the tm:local-request route, I am trying to modify the body of outgoing NOTIFY messages using the subst_body() function. Things seem to work fine most of the time. The NOTIFY messages are correctly modified. However, I will very rarely hit a crash. I can force the crash to happen more quickly by stress testing with thousands of NOTIFY messages being modified. Is it safe to call subst() or subst_body() inside the tm:local-request route? If not, is there another way I can modify the outgoing NOTIFY messages safely? Note that I am also calling append_hf() inside the same tm:local-request route, but that has been working for a very long time without causing any problems. Could there be some kind of bad interaction between append_hf() and subst_body()? Strangely, it seems like using subst() makes the crash more likely to happen. For some reason, subst_body() seems to be more robust. Here are the logs I see: --------- Jul 28 10:57:40 SIPCOMM-VEGAS-TEST /usr/local/sbin/kamailio[2476]: CRITICAL: <core> [data_lump.c:292]: del_lump(): offset exceeds message size (1625 > 1194) aborting...

Usleep on Reply
by Nicolas Breuer 01 Aug '17

01 Aug '17

Hello All, I'm trying to code something on the on_reply part to do something if I receive a 183 ( Session in progress ) , followed immediately by a "180" I tried to sleep 1 second the 183 and recheck if I received before a 180 but seems the "sleep" function sleeps everything ( also the received 180 ) Is a developper can confirm that ? The goal is to detect if a 180 follow the 183.

uac_auth credentials
by Volkan Oransoy 01 Aug '17

01 Aug '17

Hi all, I use UAC module for remote registrations on my proxy box. There is no problem with incoming calls and I successfully register and receive calls. I have a Freeswitch box behind this proxy box and I want my proxy to add authorisation headers for outgoing calls transparently. I already have credentials at uacreg table for remote registrations. Is it possible use same credentials at uac_auth() function? Or should I run SQL to retrieve necessary fields to feed uac_auth? Thanks! /Volkan
