This is the standard Kamailio behavior. Thus, you should apply NAT traversal techniques to instruct Kamailio to reuse the established connection. In short: for each register call fix_nated_register(). For every other request and response call fix_nated_contact(). Thus, if you use the default configuration and apply NAT traversal it should work. regards klaus ------------------------------ Message: 2 Date: Wed, 31 Mar 2010 11:37:27 +0200 From: Daniel-Constantin Mierla <miconda(a)gmail.com> Subject: Re: [Kamailio-Users] Registrar: Save modified contact / set the q value To: Ovidiu Sas <osas(a)voipembedded.com> Cc: NeoTel Lists <MailingLists(a)neotel.at>, users(a)lists.kamailio.org Message-ID: <4BB317D7.4030102(a)gmail.com> Content-Type: text/plain; charset=ISO-8859-1; format=flowed On 3/30/10 8:29 PM, Ovidiu Sas wrote: > If you need this in 1.5, try to fix the contact header and then > forward the REGISTER back to yourself. > The loopback REGISTER should have the fixed Contact header and now you > can call save(). > You will need to tweak a a little bit the config to get everything > right into the usrloc (the loopback REGISTER will come from the server > IP) and it might work. > it works for no nat scenario, otherwise make sure you will get the looped message on the same socket and you add before looping a header with source ip and port (corresponding nat box pinhole) that you store in received avp.

Any PV has a string representation of the value, comparison is done as integer if both PVs are integers, otherwise is done as string. The safe side is to use PV representation of selects when comparing with another PV. PV and selects is another point for the future coherence.

[Kamailio-Users] more type conversion wonders
by jh＠tutpro.com 31 Mar '10

31 Mar '10

i played a bit more with selects and found that statement if ($sht(auth=>foo::count) > @cfg_get.local.gw_timeout) { xlog("foo"); } produces error 0(9213) : <core> [cfg.y:3379]: parse error in config file /etc/sip-proxy/sip-proxy.cfg, line 507, column 28-55: bad expression: type mismatch: str instead of int at (507,55) but the error goes away if i either make explicit conversion if ($sht(auth=>foo::count) > (int)(a)cfg_get.local.gw_timeout) { xlog("foo"); } or use $sel if ($sht(auth=>foo::count) > $sel(cfg_get.local.gw_timeout)) { xlog("foo"); } this is thus exactly opposite than in my t_set_fr ordeal where i got conversion error when i used $sel instead of @. in my opinion, no (int) conversion should be needed in the firs case, because the value of the cfg variable is int. in summary, writing statements that include selects is very difficult and error prone. -- juha

[Kamailio-Users] Registrar: Save modified contact / set the q value
by NeoTel Lists 31 Mar '10

31 Mar '10

Hello Everybody! Is there any way to save(domain, 0x02) the contact after it has been changed somehow in Kamailio <= 1.5? Do I have to upgrade to 3.0 and use msg_apply_changes() before save()? Or: Can I set the to be saved q value somehow? br Walter

[Kamailio-Users] Quick REGEX to match Private IP
by Uriel Rozenbaum 30 Mar '10

30 Mar '10

Hi guys, Does anyone have a REGEX syntax to match a private IP on the 192.168.x.x range? I'm trying with: if($avp(s:ip_origen)=~"192.168(\.([1]?\d{1,2}|2[0-4]{1}\d{1}|25[0-5]{1})){2}" ) But all IPs pass as private, even public ones. Thanks! Uriel

[Kamailio-Users] Fast lock loop with arm
by Zappasodi Daniele 30 Mar '10

30 Mar '10

Hi, I have a big problem with fast lock mutex on arm CPU: sometimes I find one or more children that go in an infinite loop, in the while loop of get_lock function. They remain in Run for long time (sometimes hours) and openser keeps 100% CPU. Now I have changed the functions get_lock and tsl in order to obtain more info and I observe that (if and) when the process finish the cycle, it have done a big amount of cycles. This the log with my added info: Mar 26 20:29:08 SAM-IP openser[1645]: NOTICE:tm:_lock: ret 1 (cycle) Mar 26 20:29:51 SAM-IP openser[1645]: NOTICE:tm:_lock: ret 1 (cycle) Mar 26 20:29:55 SAM-IP openser[1645]: NOTICE:tm:_lock: ret 1 (cycle) Mar 26 20:29:55 SAM-IP openser[1645]: NOTICE:tm:t_retransmit_reply: MYTM lock [process in loop] Mar 26 20:33:46 SAM-IP openser[1645]: NOTICE:tm:_lock: ret 59374917 (cycle) [after 4 minutes and 59374917 cycles, this is an example with a "short" loop] Mar 26 20:33:46 SAM-IP openser[1645]: NOTICE:tm:t_retransmit_reply: MYTM lock done I'm not able to recognize the call flow that generates the loop (I know only that it always happens when t_retransmit_reply calls LOCK_REPLIES), but I urgently need a work around to escape from the loop. This is the get_lock function with my counter j: inline static int get_lock(fl_lock_t* lock) { #ifdef ADAPTIVE_WAIT int i=ADAPTIVE_WAIT_LOOPS; int j=1; /***** my change ****/ #endif while(tsl(lock)){ #ifdef BUSY_WAIT #elif defined ADAPTIVE_WAIT j++; /***** my change ****/ if (i>0) i--; else sched_yield(); #else sched_yield(); #endif } return(j); } Can I break the lock when my counter reaches a big value? Should I call the unlock function after the break? which value can be considered too big?

[Kamailio-Users] Kammailio as proxy and clustered asterisk as registrar
by Vic Jolin 30 Mar '10

30 Mar '10

Hi, I would like to seek help from the list regarding my setup. I have kamailio setup to send any sip messages to load balance asterisk clusters. The registration part is successful. The calling part is not, calls get dropped, I believe it's rtp issue or maybe nat. I'm very new to kamailio and would like to ask for help on this. Tia!

[Kamailio-Users] kam 1.5 sqlops sql_query timeout value
by Robert McGilvray 30 Mar '10

30 Mar '10

Hello, I'm using the sqlops module for some custom queries against mysql. Sometimes during a cluster failure the mysqld nodes will hang there waiting for the backend to finish up whatever it's doing, it still accepts the connection and the query but doesn't return results. I have a pair of F5 load balancers in front of the two sql nodes, so there is redundancy as long as the cluster is operational. I'd prefer to keep the cross-site failover in kamailio. I looked through the docs on sqlops and I can't find any reference to a timeout value. I'd like to implement a failover in the script to my other database cluster but if kam waits for a long time before returning a negative it may not work very well. Consider this code in my script for 911 services in my US offices: (I rewrite the rpid/pai and ruri based on IP address then send it to my provider(s)) modparam("sqlops","sqlcon","gokam=>mysql://*****:*****@172.20.180.21/sip _gokam") if (!sql_query("gokam", "select location,cidname,cidnum,ciddomain,e911number,inet_ntoa(network) as network,inet_ntoa(netmask) \ as netmask from e911 where (inet_aton('$si') & netmask) = network", "result")) { sl_send_reply("500", "Database error"); exit; } What I'd like to do is: modparam("sqlops","sqlcon","gokam=>mysql://****:****@172.20.180.21/sip_g okam") modparam("sqlops","sqlcon","gokam_site2=>mysql://*****:*****@172.23.180. 21/sip_gokam") if (!sql_query("gokam", "select location,cidname,cidnum,ciddomain,e911number,inet_ntoa(network) as network,inet_ntoa(netmask) \ as netmask from e911 where (inet_aton('$si') & netmask) = network", "result")) { xlog("L_CRIT", "Primary database failure, using alternate\n"); if (!sql_query("gokam_site2", "select location,cidname,cidnum,ciddomain,e911number,inet_ntoa(network) as network,inet_ntoa(netmask) \ as netmask from e911 where (inet_aton('$si') & netmask) = network", "result")) { sl_send_reply("500", Database error"); exit; } What is the default timeout for sql_query before it returns a negative, is it configurable?
