rport
by Marc Soda 28 Mar '14

28 Mar '14

I have a Kamailio server forwarding REGISTERs to an Asterisk box, similar to the way Daniel shows here: http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb Can I force Kamailio to append rport=5060 to the topmost Via header, prior to forwarding the REGISTER to Asterisk? I tried add_local_rport() but it only included 'rport' and not 5060. Thanks, Marc

SIP Connection questions
by GRIBANOV, Oleg 28 Mar '14

28 Mar '14

Dear sirs, I would like to make some tests of the SIP connection using your server. Could you please confirm me the following details: - IP of the server? Is it 212.79.11.155 ? - How could I register and use the STUN server ? What is the address of STUN server ?

Integrating Kamailio and Freeswitch
by mark li 27 Mar '14

27 Mar '14

Hi there. I'm a noobie to Kamailio and Freeswitch... but I'm trying to follow the article located here: http://kb.asipto.com/freeswitch:kamailio-3.1.x-freeswitch-1.0.6d-sbc I've tried to add all the sections marked with WITH_FREESWITCH in the sample config in the article into my own kamailio-advanced.cfg file. Here's what my cfg file looks like: http://pastebin.com/KsvrYVN7 I've restarted kamailio after making these changes. Then I tried to dial 41 to listen to vmail or 44999 to leave a message for user 999 but both return a busy tone. Any suggestions would be appreciated. Thanks.

Need to confirm the changes for the Kamailio.cfg
by varun pratapsingh 27 Mar '14

27 Mar '14

HI All, This is my first post to this community and I am new user of the Kmailio. I want to use the Kamailio and RTPProxy on the same machine. I have installed and rtpproxy succesfully and I have started both the kamailio and RtpProxy. My RtpProxy is listening on localhost:7722 port of my local machine. Now this machine is on the public IP and I want that all sip and RTP passes though this machine from SIP Softphones before going to the SIp Server. This means the machine on which I am running the Kamailio and RTPProxy will act like a SIP proxy from my SIP Softphones through which the SIP and RTP relays. SIP is relaying fine with defult kamailio.cfg but can anyone let me know the changes in Kamailio.cfg so that my RTP also passes or rleays through this Kamailio + RTPProxy machine. Thanks in advance. Thanks and Regards Varun

Preventing information about my sip network
by Arya Farzan 27 Mar '14

27 Mar '14

I'm concerned about others reverse engineering their way into my project's sip network. Is there anyway to prevent others from finding out that the SIP protocol is being used and prevent others to reverse engineer their way into my sip network?

Rewrite SIP INVITE
by Mickael MONSIEUR 26 Mar '14

26 Mar '14

Hello, I installed kamailio and asterisk with the tutorial of asipto. For alias numbers I configured the module alias_db. Everything works because Asterisk outgoing call is directed at Kamailio, then Kamailio is sending to the alias registered (table location) Only the number alias appears in the "To" (02XXXXXX) and not in the INVITE URI. It only shows "s" ... is it possible to force writing 02XXXXXX instead of "s" ? Example: INVITE sip:s@10.1.0.191:5060 SIP/2.0 Max-Forwards: 69 From: "0475XXXXXX" <sip:1053212@sip.domain.com>;tag=as7df9ab18 To: <sip:02XXXXXX@kamailioIP:5060> Contact: <sip:1053212@asteriskIP:5060> Call-ID: 344d42bd16975a54141d11f635bdfc71(a)sip.domain.com CSeq: 102 INVITE Date: Wed, 26 Mar 2014 15:06:01 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH Supported: replaces, timer Content-Type: application/sdp Content-Length: 252 Because without it, Asterisk servers behind Kamailio not will route the call to the correct extension but to the "s". Asterisk ignores the "To" apparently this is strange ... Thank you, Mickael

mediaproxy-ng, invalid header version

Using Kamailio with a SIP Trunk
by Rizwan Khan 26 Mar '14

26 Mar '14

I want the following setup: 1 Kamailio server to handle internal calls (A/V), IM and Presence. 1 Asterisk or any other way to communicate with an NGN where I will create the SIP Trunk to route calls outside of the network. Is this the right approach or there is a way to directly communicate with the NGN to make a SIP trunk by using some external modules. Any guidelines will be highly appreciated. Rizwan Khan

Memory leak when using db_unixodbc, help tracking it down (try 2)
by Alex Villacís Lasso 26 Mar '14

26 Mar '14

I have a CentOS 6 installation with the following packages installed from the RPM build service from Kamailio: kamailio-unixodbc-4.1.2-1.1.x86_64 kamailio-4.1.2-1.1.x86_64 kamailio-presence-4.1.2-1.1.x86_64 kamailio-utils-4.1.2-1.1.x86_64 I am also using db_unixodbc for all database accesses (with MySQL backend). The problem is that after a few hours, a single Kamailio process (never more than one) starts complaining that it has run out of memory: 9(11479) ERROR: uac [uac_reg.c:638]: uac_reg_tm_callback(): got sip response 408 while registering [admin_pbx.elastix.com] 9(11479) ERROR: db_unixodbc [dbase.c:335]: db_unixodbc_fetch_result(): no memory left 9(11479) ERROR: <core> [db_query.c:502]: db_fetch_next(): unable to fetch next rows 9(11479) ERROR: db_unixodbc [dbase.c:224]: db_unixodbc_free_result(): invalid parameter value 9(11479) ERROR: db_unixodbc [dbase.c:327]: db_unixodbc_fetch_result(): no private memory left 9(11479) ERROR: <core> [db_query.c:434]: db_fetch_query_internal(): unable to fetch the db result 9(11479) ERROR: presence [publish.c:108]: msg_presentity_clean(): failed to query database for expired messages 9(11479) ERROR: db_unixodbc [dbase.c:327]: db_unixodbc_fetch_result(): no private memory left 9(11479) ERROR: <core> [db_query.c:434]: db_fetch_query_internal(): unable to fetch the db result 9(11479) ERROR: presence [publish.c:108]: msg_presentity_clean(): failed to query database for expired messages 9(11479) ERROR: db_unixodbc [dbase.c:327]: db_unixodbc_fetch_result(): no private memory left 9(11479) ERROR: <core> [db_query.c:434]: db_fetch_query_internal(): unable to fetch the db result I have attached the stderr output when I kill the offending process.

However, I would like your help in focusing my search, on whether this is a known issue, or where in db_unixodbc should I look.
