Variable interpolation in xavp identifiers
by Alex Balashov 08 Apr '15

08 Apr '15

Hello, There seems to be an implementational difference in interpolation of PVs in AVP and XAVP identifiers and/or field names. The pseudovariables documentation[1] on classical AVPs says: The 'id' can be: ... pseudo variable - if value of pv is integer, id is integer, if string, id is string So, for example, this composition of variables works: $var(f) = 'donkey'; $avp($var(f) = 'eehaw'; xlog("L_INFO", "Donkey says: $avp(donkey)\n"); It correctly prints: Donkey says: eehaw Making some assumptions, I tried this, and it did not work similarly as expected: $var(f) = 'donkey'; $xavp(r=>$var(f)) = 'eehaw'; xlog("L_INFO", "Donkey says: $xavp(r=>donkey)\n"); This prints: Donkey says: <null> And a PV dump confirms that the PV value is not interpolated: Mar 31 18:26:15 localhost /usr/local/sbin/kamailio[2399]: INFO: debugger [debugger_api.c:1799]: dbg_dump_json(): {"$xavp(r)":[{"$var(f)":["eehaw"]}]} Interpolation of variables does not work for either field or stem names. Is this a design principle of XAVPs, or an oversight?

Websockets, set_contact_alias(), & IPv6
by Anthony Messina 08 Apr '15

08 Apr '15

I've been working on Kamailio websocket integration and I believe I'm having issues with the IPv6 address representation in the Contact header's alias parameter. After Googling, it appears after https://github.com/kamailio/kamailio/commit/814c08f3 the IPv6 contact is represented in brackets []. However, it when using websockets, and the alias= parameter uses brackets [] around and IPv6 address, there are message parsing issues. With a header such as the following Contact: <sip:wstest1@example.com;gr=urn:uuid:26140e27-0ab7-4e65-98e3-3d0909b1434e;alias=[2001:db8:0:1]~48768~6> Asterisk 13.2.0 will give the following error: pjsip:0 <?>: sip_transport. Error processing 1855 bytes packet from UDP 10.77.79.3:5060 : PJSIP syntax error exception when parsing 'Request Line' header on line 12 col 129: And when sipjs, or jssip are used with either Firefox or Chrome, they send garbage in the ACK request URI: Kamailio logs something like the following and the ACK cannot be processed: WARNING: sanity [sanity.c:236]: check_ruri_scheme(): failed to parse request uri [�a�{1me▒s�na@50�9��1.�8:�2v0;i��a��=11>7�n7x>10O�2v0~1] Is it proper to have [] brackets around the IPv6 alias address in the Contact header? Does the value need to be quoted? If I force the browser to use IPv4, without changing anything else, both jssip and sipjs work perfectly in Firefox and Chrome. -- Anthony - https://messinet.com/ - https://messinet.com/~amessina/gallery 8F89 5E72 8DF0 BCF0 10BE 9967 92DC 35DC B001 4A4E

Hi there, I have noticed that my kamailio proxy, version 4.2.2 is originating core dumps. This happens when Kamailio receives an INVITE in failure route, then execute the function async_sleep(3), after that changes request uri, then it stops with following error message shown below: <core> [mem/f_malloc.c:586]: fm_free(): BUG: fm_free: bad pointer 0x7f8d26605ed8 (out of memory block!), called from <core>: parser/msg_parser.c: set_path_vector(822) - aborting Please see the attachment that contains the " gdb bt full" from core.dump originated Thank you for your attention Best Regards -- Cumprimentos José Seabra

Recommendation for toggling MSILO m_store auto-notification reply on/off
by Anthony Messina 02 Apr '15

02 Apr '15

Using Kamailio 4.2-dev and MSILO, is it possible to "toggle" the auto- notification reply MESSAGE using something similar to the following where "$var(msilo_reply)" is emtpy at startup (or are there suggestions for a better method): modparam("msilo", "from_address", "$var(msilo_reply)") ... if(CONDITION WHERE I WANT THE AUTO-REPLY RETURNS POSITIVE) { $var(msilo_reply)="$rU(a)example.net"; } m_store($rU) ... My use case is that I would like the auto-notification reply to occur in some instances, but not others. I also do not want to create a loop where the auto-notification replies are also stored. I was originally using a simple test: if(src_ip!=myself), but I have begun to use the IMC module as well as the EXEC module and these MESSAGEs appear to originate from "myself." Looking at the MSILO documentation I see there is "extra_hdrs(string)," but this appears to be designed to add headers to dumped MESSAGEs. I was hoping there would be a way to add a custom header to the auto-notification, on which I could filter/drop generated replies earlier in the route, but it doesn't appear that this exists. My preference for the best-case scenario would be to control the generation of the auto-notification reply in the first place rather than having to add a control to detect the reply and drop it. Thanks in advance for any recommendations. -- Anthony - https://messinet.com/ - https://messinet.com/~amessina/gallery 8F89 5E72 8DF0 BCF0 10BE 9967 92DC 35DC B001 4A4E

Nonce lifetime in RADIUS auth module
by Måns Nilsson 31 Mar '15

31 Mar '15

Hi, I have a problem with stale nonces being reused by a UA. I'd like to do two things; * Set the nonce lifetime to a lower value * Handle stale nonces in my authentication route For the first, I'm interpreting the RADIUS module documentation so that it gets such parameters from the generic auth module and, therefore, I should be good with something like: ... modparam("auth", "nonce_expire", 60) # Set nonce_expire to 60s ... For the second, I'd appreciate pointers on how to set stale=true in the 401 reply, if special handling is required. I have incomplete packet traces to work from right now, so can't tell if it is being set already. Thanks, -- Måns Nilsson primary/secondary/besserwisser/machina MN-1334-RIPE +46 705 989668 I'm wearing PAMPERS!!

htable persistation question
by Attila Megyeri 31 Mar '15

31 Mar '15

Hi, We are having problem with persisting htable. There are 4 hashtables defined in kamailio config, like: modparam("htable", "db_url", DBURL) modparam("htable", "htable", "vtp=>size=10;autoexpire=120;dbtable=htable;dbmode=1;") modparam("htable", "htable", "a=>size=6;") modparam("htable", "htable", "rpn=>size=10;autoexpire=0;dbtable=htable;dbmode=1;"); modparam("htable", "htable", "rpnn=>size=10;autoexpire=0;dbtable=htable;dbmode=1;"); The strange behavior is that if I restart kamailio, the hash table is not persisted into the database. If I change e.g. rpn's dbtable to e.g. htable_1 (which should be created in the kamailio mysql database schema upfront, then the rpn hashtable will be presisted successfully at every stop and will be reload at every start. What is wrong in my config? Kamailio version is 4.2.3 Thanks, Attila

Hi all I'm sharing a location table between two kamailio 3.3 and kamailio 4.2 servers. Table versions are 5 and 6 but I don't know how to skip table version checking to prevent one of them from running. Any tips? thanks, Jon
