issues with RTP on different hosts & dispatcher mod
by Infinicalls Infinicalls 02 Nov '15

02 Nov '15

Hi, I whenever I try to add rtpproxy to my config file modparam("nathelper", "rtpproxy_sock", "udp:firsthost:12221 udp:secondhost:12221") , I get this error. 0(45810) ERROR: <core> [modparam.c:139]: set_mod_param_regex(): parameter <rtpproxy_sock> of type <1> not found in module <nathelper> 0(45810) : <core> [cfg.y:3435]: yyerror_at(): parse error in config file /usr/local/etc/kamailio/kamailio.cfg, line 423, column 82: Can't set module parameter ERROR: bad config file (1 errors) 0(45810) INFO: <core> [sctp_core.c:53]: sctp_core_destroy(): SCTP API not initialized I am having with_nat. Secondly, I tried with dispatcher and it works for one way calls. ie. User1 is able to call User2, but vice versa is not possible. Both RTP1 and RTP2 are in different machines and Kamailio sits on a different machine. All have identical network setups. And no NAT. Any idea. Can somebody guide me? thanks. regards Ganesh Kumar

100% CPU usage after NTP date update
by Stefan Kohlhauser 02 Nov '15

02 Nov '15

Hello everyone! Setup: I am currently using a Kamailio 4.2.3 on an embedded device (low CPU and RAM). The device is not able to store the current date, so after a reboot its 1. Jan 1970 until NTP updates the date. Problem: If the date is updated after the Kamailio has started (a leap of 45 years) the Kamailio uses up all the CPU and renders the device useless for a very long time. Notes: There are no incomming requests at the time. (But the Kamailio is not responsive during that time anyway.) Adjusting the internal Kamailio-time seems to take longer when the date update leap is bigger. My questions: 1) Can I prevent the Kamailio from using up the entire CPU after a date update? Or maybe do the internal ticks-update more gracefully? 2) For my better understanding: What happens within the Kamailio after adjust_ticks has updated the internal date? Thanks in advance for your help! Best regards, Stefan

Multi-Array with AVPs
by Jonathan Hunter 02 Nov '15

02 Nov '15

Hi Guys, Hope all are well? sorry to post but Im just trying to get something working where Im trying to convert a php function script into the kamailio.cfg. Im getting there but wonder how I can group results of sets of avps with another avp. Say I have these variables; $(avp(NTgrp)) = 'SB100_000361@1.2.3.4|SB100_000213@1.2.3.5|SB100_000225@1.2.3.6|SB100_000361@1.2.3.7|SB100_000213@1.2.3.8';$(avp(Prio)) = '1|1|1|2|2';$(avp(Wgt)) = '10000|10000|80000|30000|70000';$(avp(CInc)) = '0|0|1|0|1';$(avp(WTot))= '100000|100000|100000|100000|100000'; I then run a while script to split up their variables via the delimiter | in user; $var(j)=0;while($var(j)<$var(count)) {$(avp(NTgrpP))=$(avp(NTgrp){s.select,$var(j),|});$(avp(PrioP))=$(avp(Prio){s.select,$var(j),|});$(avp(WgtP))=$(avp(Wgt){s.select,$var(j),|});$(avp(CIncP))=$(avp(CInc){s.select,$var(j),|});$(avp(WTotP))=$(avp(WTot){s.select,$var(j),|});xlog("L_INFO"," Now Each time we have $(avp(NTgrpP)) $(avp(PrioP)) $(avp(WgtP)) $(avp(CIncP)) $(avp(WTotP))\n");$var(j)=$var(j)+1;} This then results in;INFO: <script>: Now Each time we have SB100_000223(a)1.2.3.4 1 10000 0 100000INFO: <script>: Now Each time we have SB100_000225(a)1.2.3.5 1 10000 0 100000INFO: <script>: Now Each time we have SB100_000386(a)1.2.3.6 1 80000 0 100000INFO: <script>: Now Each time we have SB100_000213(a)1.2.3.7 2 30000 0 100000INFO: <script>: Now Each time we have SB100_000361(a)1.2.3.8 2 70000 0 100000 Now what Id like to do is group them via priorities so I can do some further functional checks on them when in same priority group, as you can see there are 3 results at priority 1 and 2 at priority 2. Is there away I can create something of a multi-array using the AVP $(avp(PrioP)) I just created so I can group by priority? As in php I would do something like; $multi_arr[$prio_arr[$p]][] = array( "ntgrp" => $ntgrp_arr[$p], "prio" => $prio_arr[$p], "wght" => $wght_arr[$p], "cinc" => $cinc_arr[$p], "wtot" => $wtot_arr[$p], ); } Any help would be great. Many thanks Jon

Q: about CRL list (TLS)
by Vladimer Gabunia 02 Nov '15

02 Nov '15

hello all. we compiled kamailio with TLS Support. but have next problem when using CRL Lits. Our Certificate issuing scheme is follow: Offline Root CA -> Enterprise SubCA -> Server and Phone Certificate CRL list is signed by SubCA. option "require client certificate is enables (1) " When we enable CRL list, phones are not registered. CA file is offline RootCA certificate in pem format. We think that the reason is that СRL was signed by Subca or incorrect CRL format. CRL is converted from MS CRL to PEM. (What is the format for the CRL) maybe someone have experiance with similar scenarios? thanks in advance!! ________________________________ [gh.ge] ვლადიმერ გაბუნია IT სამსახურის უფროსი ტელ: (+995) 32 2505222 +8183 მობ: (995) 577 095333 შპს "ჯეო ჰოსპიტალს" სათავო ოფისი თბილისი 0160, ვაჟა-ფშაველას გამზ. № 16; http://www.gh.ge <http://gh.ge>

Problems with dispatcher module | feature disabled
by Alessio Casco 02 Nov '15

02 Nov '15

Hello! We noticed today an issue with the kamailio loadbalancing. Basically kamailio is not considering if an host is up or not, backends are set always as "FLAGS: AP" even if the host is down. I see this when the proxy starts : ERROR: dispatcher [dispatcher.c:768]: ds_warn_fixup(): failover functions used, but required AVP parameters are NULL -- feature disabled These the parameters I have set: # ----- dispatcher params ----- modparam("dispatcher", "list_file", "/etc/kamailio/dispatcher.list") modparam("dispatcher", "dst_avp", "$avp(dsdst)") modparam("dispatcher", "grp_avp", "$avp(dsgrp)") modparam("dispatcher", "cnt_avp", "$avp(dscnt)") modparam("dispatcher", "ds_ping_method", "OPTIONS") modparam("dispatcher", "ds_ping_reply_codes", "class=2;class=3;code=404") modparam("dispatcher", "ds_ping_from", "sip:proxy@sip.nexmo.com") modparam("dispatcher", "ds_ping_interval", 20) modparam("dispatcher", "ds_probing_threshold", 1) modparam("dispatcher", "ds_probing_mode", 1) modparam("dispatcher", "ds_hash_size", 10) modparam("dispatcher", "ds_hash_expire", 3600) modparam("dispatcher", "ds_hash_initexpire", 60) modparam("dispatcher", "ds_hash_check_interval", 10) modparam("dispatcher", "use_default", 0) modparam("dispatcher", "attrs_pvname", "$avp(carrierattr)") modparam("dispatcher", "setid_pvname", "$avp(carriergroup)") modparam("dispatcher", "flags", 2) I use 4.3.3, I think this issue started after upgrading from 4.3.1 but I can't say for sure. Can someone please give us some advices on this? Thanks Alessio

I configured the tls options: disable_tls = 0 listen=tls:192.168.50.60:5061 tls_certificate="/etc/kamailio/tls/crt.pem" tls_private_key="/etc/kamailio/tls/key.pem" tls_ca_list="/etc/kamailio/tls/ca.pem" tls_verify_client=on tls_require_client_certificate=on I need to check certificate revocation, but the option tls_crl does not work. Which option uses for check certificate revocation in kamailio 1.5.x ?
