Kamailio -topoh- and Via headers
by Gonzalo Gasca 08 Oct '14

I'm using Kamailio as SIP Registrar using Websockets. My topology looks like this: Sip client (sipml5) ---> wss ---> Nginx ---> ws ---> Kamailio 4.1.5 When I look into my SipMl5 application in the Register Message 200 OK from Kamailio I see the Nginx private IP address 172.31.22.2 Via: SIP/2.0/WSS df7jal23ls0d.invalid;rport=37111;received=172.31.22.2;branch=z9hG4bKtv75otkzmPVsdNWevweLt4TN9JnLnQ0p How can I remove private IP Address in Via header to achieve topology hiding? >From Kamailio logs: Oct 6 00:34:21 ip-172-31-27-85 /usr/sbin/kamailio[8941]: DEBUG: registrar [reply.c:374]: build_contact(): created Contact HF: Contact: <sips:gogasca@df7jal23ls0d.invalid;rtcweb-breaker=no;transport=wss>;expires=200#015#012 Oct 6 00:34:21 ip-172-31-27-85 /usr/sbin/kamailio[8941]: DEBUG: sl [sl.c:288]: send_reply(): reply in stateless mode (sl) Oct 6 00:34:21 ip-172-31-27-85 /usr/sbin/kamailio[8941]: DEBUG: <core> [msg_translator.c:204]: check_via_address(): check_via_address(172.31.22.2, df7jal23ls0d.invalid, 0) O Version: kamailio 4.1.5 (x86_64/linux) # ------ topoh -------- modparam("topoh", "mask_key", "opencall") modparam("topoh", "mask_ip", "<Public IP Address of Kamailio>") modparam("topoh", "vparam_prefix", "llamato") modparam("topoh", "mask_callid", 1) modparam("topoh", "sanity_checks", 1)

Thanks Daniel, I'm trying to use sqlite (mysql is too "heavy" for my environment) but usually I receive a lot of commit failed because database is locked (especially in presentity.c and publish.c) Is there any way to manage, maybe i've missed some sqlite configuration parameters? ----Messaggio originale---- Da: miconda(a)gmail.com Data: 6-ott-2014 18.17 A: "Marino Mileti"<marino.mileti(a)alice.it>, "Kamailio (SER) - Users Mailing List"<sr-users(a)lists.sip-router.org> Ogg: Re: [SR-Users] Presence PUBLISH error hello, It seems that the column type and value type are mismatching, but they can still be compatible. The fact is that db_text was not designed to handle large data values, so not tested with presence. Eventually you may want use sqlite (or other db module) instead or go into db_text and update as needed.

rtpengine with rejected re-invites to new RTP ports
by Jeff Pyle 08 Oct '14

08 Oct '14

Hello, Given the following scenario with Kamailio and rtpengine in the middle: - call establishes with G.711 RTP - b-leg re-invites to T.38, indicating a different port number then he is using for G.711 - a-leg refuses the re-invite with a 488 - call continues using G.711 on original port numbers as if re-invite never happened Will Kamailio and rtpengine handle it? Today I have a functional configuration with rtpproxy on another SIP proxy. It handles every scenario I have tried except this one. rtpproxy sees the new ports in the re-invite and adjusts its session accordingly. If the re-invite is rejected, the old media ports are no longer valid through rtpproxy, and the call fails. Is there an approach I can take with Kamailio and rtpengine to allow this scenario to succeed? Regards, Jeff

tcp_read_data() errors in syslog
by Petr.Wozniak＠seznam.cz 07 Oct '14

Hello All, I have installed kamailio with TLS module together with siremis on server and all seems works fine except that sometimes appear in syslog file the following errors: /usr/sbin/kamailio[3266]: ERROR: <core> [tcp_read.c:289]: tcp_read_data(): error reading: Connection timed out (110) /usr/sbin/kamailio[3266]: ERROR: <core> [tcp_read.c:1281]: tcp_read_req(): ERROR: tcp_read_req: error reading /usr/sbin/kamailio[3268]: ERROR: <core> [tcp_read.c:289]: tcp_read_data(): error reading: Connection reset by peer (104) Some part of syslog please you find enclosed. I don't know where I should search for the cause of these errors and how to debug and remove them. I don't know if these errors are caused by incorrect kamailio configuration or are caused on client's side. Thank you for your opinions and help in advance Regards, Petr

multiple endpoints call
by Marino Mileti 07 Oct '14

07 Oct '14

Take a look at : modparam("registrar", "max_contacts", x) to have up to "x" contacts for AOR and in your REGISTRAR route if your save("location") has some extra parameters (for example the 0x04 used to restrict one single record in loaction table ----Messaggio originale---- Da: ovoshlook(a)gmail.com Data: 6-ott-2014 22.02 A: "Kamailio (SER) - Users Mailing List"<sr-users(a)lists.sip-router.org> Ogg: [SR-Users] multiple endpoints call Hello. I have multiple endpoints registered at my kamailio with one account (for example user1 registerd from norhway, USA, and Russia at one time), so when I call from user2 to user1 I want to ring all endpoints registered by user1 account. Now I can ring only one, first entry at location table. What setting may I use for this? Thanks
