uacreg issue
by Lucas Alvarez 09 Nov '11

09 Nov '11

Hi, after following the steps of this guide: http://by-miconda.blogspot.com/2010/10/best-of-new-in-kamailio-310-10.html, poulating the uacreg table, loading the uac module and restarting kamailio I didn't see any REGISTER packet sent out to the sip provider, is something missing? How can I know if the values from the table are being loaded? I would appreciate any kind of help. Regards, Lucas Alvarez

negative www_authorize result codes
by Juha Heinanen 09 Nov '11

09 Nov '11

auth_db/README tells this about www_authorize() negative result codes: Negative codes may be interpreted as follows: * -1 (generic error) - some generic error occurred and no reply was sent out; * -2 (invalid password) - valid user, but wrong password; * -3 (invalid user) - authentication user does not exist. whereas in auth_radius i return: Negative result codes may be interpreted as follows: * -7 (internal error) - some internal error occurred (see syslog); * -6 (nonce reused) - nonce is used more than once; * -5 (no credentials) - credentials were not found in request; * -4 (stale nonce) - stale nonce; * -3 (authorization failed) - RADIUS responded with Access Reject which may be, for example, due to user not found or wrong password; * -1 (error) - some error occured during authorization (see syslog); since both modules depend on the same auth module, why does www_authorize return the full set of negative result codes or is its README out of date? -- juha

uacreg question
by Lucas Alvarez 08 Nov '11

08 Nov '11

Hi, I have properly populate the table "uacreg" as says here: http://by-miconda.blogspot.com/2010/10/best-of-new-in-kamailio-310-10.html and I'm loading the uac module, is there anything I could be missing? Because I'm not seeing any register packet being sent to my sip provider. Thanks in advance, Lucas Alvarez

how to give integer avp name in pseudo variable?
by Juha Heinanen 08 Nov '11

08 Nov '11

i have not been able to figure out, how to give integer avp name in a pseudo variable. test $var(name) = "i:1000"; $avp($var(name)) = "value"; xlog("L_INFO", "avp i:1000 has value <$avp(i:1000)>\n"); xlog("L_INFO", "avp s:i1000 has value <$avp(s:i:1000)>\n"); produces to syslog Nov 8 13:17:23 sip /usr/sbin/sip-proxy[8642]: INFO: avp i:1000 has value <<null>> Nov 8 13:17:23 sip /usr/sbin/sip-proxy[8642]: INFO: avp s:i1000 has value <value> that is, $var(name) value i:1000 is interpreted as string name even when its syntax conforms to integer name. is this is a bug or how should value of $var(name) look like? -- juha

Conditional uacreg
by Alex Balashov 08 Nov '11

08 Nov '11

Is there some way by which credentials can be loaded into the uacreg table, but not all of them used at once? The problem I have is a need to make these registrations active and inactive periodically, whereas the registration facility that the uac module provides is fully managed/largely unattended. Using $uac_req(...) is not an option because I need to capture the failure replies (which is not supported in TM) in order to do digest challenge authentication. -- Alex Balashov - Principal Evariste Systems LLC 260 Peachtree Street NW Suite 2200 Atlanta, GA 30303 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/

Can Kamailio send routes to and /or receive routes from SQL Server? Is there any way for Kamailio to connect to SQL Server in general? Thanks Jonny

That's mixed. Thus I advice you to switch the order of IP addresses so that internal is 192... and external is 109... This is essential to use the i,e flags correctly. > I'm getting RTPstats published on Kamailio/RTPproxy syslog. > > I am using Echo() application in asterisk.

Thus I suspect that the RTP packets from Asterisk to the public rtpproxy interface do not even arrive at rtpproxy. > > The # DTMF signal sent from Client phone reached asterisk safely and > terminated the Echo() application. > > I did the ip_forwarding thingie too.-- somebody mentioned to do this if > using RTPproxy in bridged mode. This is bullshit. People seem to not understand IP at all. rtpproxy is forwarding in user mode - it receives on a UDP socket and sends on a UDP socket. Thus, kernel based forwarding is not involved when using rtpproxy. You can disable IP forwarding again. > #echo "1" >> /proc/sys/net/ipv4/ip_forward > #sysctl -p > > > Here are the corresponding Logs from Kamailio and rtpproxy. The thing is quite easy. Swap the IP addresses when starting rtpproxy and then configure Kamailio to call rtpproxy with the proper i,e flags (as described in my previous email). For example: if (has_body("application/sdp")) { if ($si == "192.168.2.75") { # message from internal to external rtpproxy_manage("ie"); } else { # message from external to internal rtpproxy_manage("ei"); } } Put above code block in the main route block and also in a reply route which will be activated (or in the default reply route). Put some xlog statements around the rtpproxy calls to verify the proper command is called. regards Klaus
