[Kamailio-Users] 30x Redirect / Forward, even questions
by Samuel Muller 26 Jan '10

26 Jan '10

Hello all, I've questions 'bout the redirect/forward with 30x requests. Actually, it does not work, it seems the uac redirect module doesn' t use the new contact for the new invite. simple schema : pstn gw -> kamailio -> linksys -> call forward unconditionnal to another pstn number -> kamailio -> gw pstn the 302 as seen with ngrep tool : #SIP/2.0 302 Moved Temporarily. #To: <sip:B@sip_proxy;user=phone>;tag=91515579fff6b8d1i0. #From: <sip:A@pstn_gw1;user=phone>;tag=16627-UI-00020cf3-54eea92c4. #Call-ID: 16627-RO-00020cf2-4186e9762@pstn_gw1. #CSeq: 81990 INVITE. #Via: SIP/2.0/UDP sip_proxy;branch=z9hG4bK0f0c.22989b87.1. #Via: SIP/2.0/UDP pstn_gw1:5060;rport=5060;received=ip_pstn_gw1;branch=z9hG4bK-25EA-243F3. #Record-Route: <sip:sip_proxy;lr=on;ftag=16627-UI-00020cf3-54eea92c4;did=f65.bcc44f06>. #Contact: <sip:C@sip_proxy>. #Diversion: "B" <sip:B@sip_proxy>;reason=unconditional. #Server: Linksys/SPA942-6.1.3(a).

I've another question, is the 30x always considered as a failure_route ? Any help and/or explanations about the tricks would be really appreciated ... thanks, -- Samuel MULLER sml(a)l33.fr

[Serusers] Questions about the command : serctl fifo
by inge 26 Jan '10

26 Jan '10

Hi, I am using SER 0.9.9. I have questions about two commands "serctl fifo" : - serctl fifo t_stats : What does mean the "current", "waiting" and "total" values returned by the command? - serctl fifo ul_stats : What does mean the two values returned on the line "location"? Regards, David.

[Kamailio-Users] Global constants
by Alex Balashov 26 Jan '10

26 Jan '10

Daniel, What is the recommended way (if any) to have a "global constant" that exists outside of any particular routes, in K3? My objective is to define a global DB_URL that can be used by all modules everywhere, but I can't just 'and' the modules together, e.g. modparam("mod1|mod2|mod3|...", "db_url", "...") because the modules are dynamically included (thanks to include_file!) and I do not know the list of all loaded modules easily at runtime. So instead, db_url is configured on a per-module basis. I thought preprocessor constants (e.g. #!define and friends) would allow me to set values for them, but they don't, so that's out. What other options are available that do not involve an event/local route, and operate instead in the completely global namespace? Right now, I am using a Perl script that manually substitutes the value of the db_url modparam everywhere in a large directory tree. :/ What am I not thinking of?

[Kamailio-Users] Active dialogs waaaay to high
by Anders 26 Jan '10

26 Jan '10

Hi, When I run 'kamctl fifo get_statistics all calls', it tells me that the the number of dialogs is about 2000 times higher than what it really is. Actually it seems like it has added a couple of thousand to the number. How do I 'reset' this number? A restart of kamailio didn't help... Thanks! //Anders

[Kamailio-Users] "Permanent" AVP
by Antonio Reale 26 Jan '10

26 Jan '10

Hi all, I'd like to simulate in kamailio 1.4.4, the loading of a global setting (like a parameter that is loaded only at startup), using AVPs. So, I want to load some AVP only at proxy startup. Probably it is not possible because, if I'm not wrong, AVPs are transaction persistent. The problem is that I don't need to load those AVPs for every transaction. There is a why to implement such configuration? Thanks. Best regards. -- Antonio

[Kamailio-Users] 477 Send failed
by vragukumar＠signalogic.com 25 Jan '10

25 Jan '10

Hello, I have setup Kamailio and rtpproxy on a server, that acts as a SIP Proxy. An asterisk server sits behind this proxy server. I have noticed that on some occasions when the softphone(x-lite) tries to register with the asterisk through the proxy,it receives a 477 send failed. If i restart Kamailio, the problem seems to disappear. I have attached a logfile showing Kamailio's error output. What could be the reason for such behavior ? Thanks and Regards, Vikram.

[Serusers] how to compile the docs?
by Chump Chumpster 25 Jan '10

25 Jan '10

Hi, I'm sure this is a simple question and hopefully a simple answer. I've downloaded and am experimenting with SER 2.0.x. I can't find any instructions on how to compile the docs included with the source, into a usable format. They're pretty difficult to use as XML without a stylesheet :-) I appreciate any advice to get me going in the right direction....

[Kamailio-Users] Fwd: TLS Multiple records not read
by Jijo Jose 25 Jan '10

25 Jan '10

Thanks for the response. The SIP server is reading only the first record(first sip message), the _tls_read() function's log shows the length of first sip message which is matching with length of first record in wireshark.. This means SSL_read returns only the first record. I did the test using TCP which is working fine as it is reading two sip messages on a single read. Please find the log and attached print screen of wireshark traces.

[Kamailio-Users] Outgoing registrations
by Andrey Utkin 25 Jan '10

25 Jan '10

How do you make outgoing registrations to sip providers' accounts? I haven't found Kamailio functionality like this, so looks this requires some b2bua usage? Is there some other way?
