drouting & rd
by Jean Cérien 22 Mar '18

22 Mar '18

Hello I have setup 2 gateways in my dr_rules: 5,6 - so the 2nd one is tried if the first fails. The second one requires credentials. When the first one fails: I execute the following code: failure_route[ROUTEFAIL] { if ( t_check_status("[345][0-9][0-9]") or (t_branch_timeout() and !t_branch_replied() )) { t_on_failure("ROUTEFAIL"); if (use_next_gw()) { xlog("L_INFO","failure_route(ROUTEFAIL) @@ routing to: rd: $rd, ru:$ru, t_relay"); t_relay(); exit; } then in the same ROUTEFAIL (before this code), I have if (t_check_status("401|407")) { xlog("L_INFO","failure_route(ROUTEFAIL) @@ call to uac_auth(), $si rd: $rd\n"); ..... So, when the first gateway replies with a 404, it executes correctly the first block, finds the second gw and I see in the log that rd is set to its address. Yet, when the 2nd gw replies with 401, rd is set to the very first gw. However, the pcap traces confirm it is indeed the second that replies this. If this behaviour is correct, I cant seem to find the source IP of the gateway that replied to me, to retrieve credentials from the db. version: kamailio 5.0.5 / 5.0.6 (tested on both) Thank you for your help J

Hi all, I have kamailio setup that uses a mongo cluster, and everything works fine. Only I have problems with the avpops module. The avp_db_load fails with "field [attribute] not found in result iterator", even if the attribute field is present in the object in mongo. Does anybody know what could be going wrong?

How does Kamailio decide which msg to store when receiving it double from 2 servers?
by Zigelman, Amit 21 Mar '18

21 Mar '18

I am using Captagent on 2 sip servers communicating with each other. Both Captagents then route the SIP traffic to the same Kamailio. Therefore, if I understand, Kamailio will get every msg between them twice. Once from server A and once from server B. Let's say that each of them has a different capturing code (100 for server A and 200 for server B) How will the data look in the DB? Will it hold both entries pretty much the same with a difference is some fields such as the capture node? Thanks a lot, Amit -- *Amit Zigelman* | *Software Developer* Mobile (+972) 54-570-9129 <+972%254-570-9129> | amit.zigelman(a)vonage.com

authenticating to mongodb fails
by hdssdsdsdsfsdf hdssdsdsdsfsdf 21 Mar '18

21 Mar '18

When I connect using mongo, the credentials work: $ mongo kamailio -u "kam" -p "kam" MongoDB shell version v3.4.9 connecting to: mongodb://127.0.0.1:27017/kamailio MongoDB server version: 3.4.9 > db.subscriber.find() { "_id" : ObjectI ... But when I use the following DBURL in kamailio.cfg, kamailio fails to even login to mongo: #!define DBURL "mongodb://kam:kam@localhost/kamailio" If I disable mongodb authentication, kamailio starts up just fine again. Any idea what's going wrong here?

NATDETECT Flag 16
by Duarte Rocha 21 Mar '18

21 Mar '18

Greetings, I have a doubt about the flag 16 used in nat_uac_test() belonging to the module NATDETECT. In the documentation, the following is stated : *16* - Test if the source port is different from the port in the “Via” header I have some situations that I receive a request from port 5060 and the Via Header contains no port. I think it probably assumes that it is the default port. Will this situation trigger the "16" flag ? Thanks in advance, Cheers

S-CSCF can not allocate memory
by tyd 21 Mar '18

21 Mar '18

Hello, I haved install debian 8 and kamailio 4.4.7 for IMS testing. After registering 10000 users, SIPp generates CPS 25 SIP INVITE message and BYE message after 100 seconds. After about 240000 calls, there are "cannot allocate memory" messgae on S-CSCF. The command of S-CSCF is "kamailio -m 512 -f /etc/scscf/kamailio.cfg" The parameter mem_join=1 is included in kamailio.cfg. I have modified the share memory to 1024 and 2048, but the result is the same, just increasing the pass calls. Would you please tell me how to solve the memory problem? Thanks.

execute only on INITIAL INVITE
by David Villasmil 20 Mar '18

20 Mar '18

Hello guys, I want to execute an sql only for INITIAL INVITEs, I'm trying like: #!ifdef WITH_DID_VALIDATE if(!has_totag()) { sql_query("acd", "select * from did_numbers where didNumber = '$tU' and active = 'Y'", "ra"); xlog("L_ERR", "[REQUEST_ROUTE] number of rows in table domain: $dbr(ra=>rows)\n"); if( $dbr(ra=>rows)==0 ) { xlog("L_ERR", "[REQUEST_ROUTE] DID Number validation returned [$dbr(ra=>rows)], not responding to this request\n"); exit; } sql_result_free("ra"); } #!endif But, say I remove the DID from the allowed list while a call is going on. Then responses to the allowed INVITE would not be processed. How would I limit that to ONLY the INITIAL INVITE? Should I use has_totag? Thanks!
