$fs syntax

wiki tells: $fs - reference to the forced socket for message sending (if any) in the form proto:ip:port should it be [proto:]ip:port instead? -- juha

Kamailio 3.2.4 presence

by Vitaliy Aleksandrov

Hi all, I'm facing problems with active subscription restoration after sipproxy restart. db_mode is 0 (DB_MEMORY_ONLY) and according to comments in the presence.h kamailio holds subscription in memory and periodically updates to db, but retrieves from db only at startup. And it's true, I see that kamailio tries to update the active_watchers table, but it never inserts new subscriptions there. There are no problems with access to the database since when db_mode is 2 (DB_ONLY) kamailio inserts new records into the active_watchers without any problems. Here are presence module settings: modparam("presence", "db_url", "sqlite:////var/db/presence.db") modparam("presence", "db_mode", 0) modparam("presence", "timeout_rm_subs", 1) modparam("presence", "pres_htable_size", 8) modparam("presence", "subs_htable_size", 8) modparam("presence", "max_expires", 3600) modparam("presence", "db_update_period", 60) modparam("presence", "clean_period", 60) Does anybody have success with db_mode = DB_MEMORY_ONLY and active_watchers db table ?

is kamilio support RFC5626 now ?

by mike

dear kamilio developers : i read the kamilio 3.3.0' s new features , it say it support outbound , and i have place to handle reg-id and sip.instance . so , i wonder if the kamilio3.3.0 support RFC5626 now，so that the kamilio can be used as a edge proxy . i ask why because i can't find where kamilio add flow-token and path for the register request. thanks

IPv6 addresses in dispatcher on IPv4 only proxy

by Alex Hermann

Hello, I am using the dispatcher module with a database table shared among multiple proxies. Some proxies do both IPv4 and IPv6, others only do IPv4. The problem is when i use an IPv6 address in the dispatcher table. Then the IPv4-only proxies fail to load the table. ERROR: dispatcher [dispatch.c:325]: could not resolve [IPv6 address] WARNING: <core> [mem/f_malloc.c:474]: WARNING:fm_free: free(0) called ERROR: dispatcher [dispatcher.c:321]: could not initiate a connect to the database ERROR: <core> [sr_module.c:889]: init_mod(): Error while initializing module dispatcher (/usr/lib/kamailio/modules_k/dispatcher.so) Is there any setting i can use on the IPv4-only proxies to make it skip the IPv6 records? (apart from listening on an IPv6 address) -- Greetings, Alex Hermann

I had a working Kamailio-3.1.5 code base without TLS 2. Downloaded latest openssl source code 3. Compiled and generated libssl.a and libcrypto.a 4. Next, I recompiled kamailio proxy, compilation did not go through. I had to modify Makefile in modules/tls module, added path for openssl/bio.h and path for libssl.a 5. Then executed make all clean and make all include_modules=tls , this time compilation succeeded 6. Next I did make install 7. Generated certificates using openssl library that comes by default with ubuntu 10.04 lte 8. Added below entries in kamailio.cfg #!define WITH_TLS #!ifdef WITH_TLS loadmodule "tls.so" modparam("tls", "config", "/usr/local/etc/kamailio/tls.cfg") modparam("tls", "private_key", "/etc/certs/localb2bua.com/key.pem") modparam("tls", "certificate", "/etc/certs/localb2bua.com/cert.pem") modparam("tls", "ca_list", "/etc/certs/demoCA/cert.pem") enable_tls=yes #!endif 9. Then I tried running kamailio proxy It complained not getting tls.so and tls.cfg Copied these files from modules/tls to /usr/local/etc/kamailio/ path 10. Then I was able to run Kamailio proxy and got the errors pasted at top of email (* Unable to load certificate file './modules/tls/ser-selfsigned.pem') * Please guide me what should I do to avoid this error. Thanks a lot. -Kamal * *

segfault in siptrace module using setflag?

by samuel

Hi folks, I was making some tests with kamailio (both 3.3.0 and 3.3.1 tgz) with siptrace module sending "homer" packets to a remote central agent where the data is stored and presented to the user. The related config is: # ----- siptrace params from HOMER ----- modparam("siptrace", "duplicate_uri", "sip:A.B.C.D:9060") modparam("siptrace", "trace_to_database", 0) modparam("siptrace", "trace_flag", 22) modparam("siptrace", "trace_on", 1) #HEPv2 == timestamp will be included to HEP header modparam("siptrace", "hep_version", 2) modparam("siptrace", "hep_mode_on", 1) modparam("siptrace", "hep_capture_id", 1) basically for all incoming messages, a route is called with the following actions: route[HOMER] { setflag(22); sip_trace(); } I've been making some tests and if I disable the setflag action, there is no problem (well, no transaction messages are sent to the central agent), but as soon as I activated setflag, kamailio crashes with the following error: <core> [pass_fd.c:293]: ERROR: receive_fd: EOF on 28 There's no concrete point in the config file where it fails so I think the problem is more tm-internals related. I can provide further information in case you need it. Just for adding information, and without any intention to start a flame-war, with opensips 1.8.0-tls the server does not crash... Thanks in advance! Samuel.

Supporting TLS and DTLS in RTP Proxy

by Kamal Palei

Hi All I am planning to enhance RTP proxy to support TLS and DTLS. We have some requirements where we need to send RTP packets either over TLS or over DTLS. I really do not know where to start :-) Few things that I have thought over is 1. I will take opnssl code base and integrate with rtpproxy code. 2. Will refer kamailio proxy code how tls connection framework is there and try to copy the code from kamailio code base to rtp proxy code base, OR is there a better alternative here. If somebody has a better idea, kindly share. Thanks a lot. -kamal
