t_drop_replies can't be used on a route?
by David Villasmil 09 Jun '22

09 Jun '22

Hello guys, I have a failure route which calls another route, and on this route I need to t_drop_replies(); But i'm getting: [core/cfg.y:3510]: yyerror_at(): parse error in config file /etc/kamailio/include/relay_routes.cfg, line 143, column 20: Command cannot be used in the block Any way to fix this without me having to use it in the failure_route?

remove header in async processing (e.g. by http_async_client)
by Henning Westerholt 09 Jun '22

09 Jun '22

Hello, I'd like to remove headers during async processing e.g. in a route called from http_async_client(..). The usual textops functions are not working here. Adding headers could be done using something like rtjson, but it do not offer a remove header function. I could of course loop the request locally, but this is not that "nice". Any other suggestions for this case? Or just the rtjson module needs some extensions? Thank you, Henning -- Henning Westerholt - https://skalatan.de/blog/ … [View More]

Siremis startup helper service for systemd
by Joseph Goettgens 09 Jun '22

09 Jun '22

Hi, I had some difficulties getting Siremis 5.3 to run under Debian 11 Bullseye. It turned out that the problem was the creation of the Siremis socket: <UnixSockLocal name="unixsocklocal" address="/run/siremis/siremis_rpc.sock" timeout="3.0"/> There is a warning in siremisJRCommands.xml that points out that systemd has to be reconfigured as sockets in /tmp are no longer shared (PrivateTmp setting). By the same token, /run/siremis/siremis_rpc.sock cannot be created as the httpd … [View More]

Re-establishment of a closed TCP connection
by Vitalii Krutsitskyi 09 Jun '22

09 Jun '22

Hello General overview of the infrastructure: Client (Cisco Hardware) ---> AWS NLB ---> Kamailio Instances The client has a time limit for the opened TCP connections - 10 minutes. This is a hardcoded value that can't not be changed. Regardless of the traffic that flows through the connection, it is closed after 10 minutes. Problem: in case of long-running calls above 10 minutes it is not possible for Kamailio to send back SIP traffic back to the client using the original TCP connection.… [View More]

ipops dns_query not working using Kemi
by Thomas de Rooij | CM.com 09 Jun '22

09 Jun '22

Hi all, We are trying to do a DNS query using Kemi: KSR.ipops.dns_query(domain, "xyz") The result is always -3. This is returned here: https://github.com/kamailio/kamailio/blob/5.5.4/src/modules/ipops/ipops_pv.… It seems weird to me that the error code is returned because the same non-Kemi code works just fine. Could it be related to this issue: https://github.com/kamailio/kamailio/issues/2052 Thanks. Kind regards, Thomas

Siremis JSONRPC problem on Bullseye
by Joseph Goettgens 07 Jun '22

07 Jun '22

Hi, I seem to have a problem setting up Siremis 5.3 on a Debian 11 box using the Kamailio 5.6.0 release (installed from repo). When I enter something like core.uptime into the JSONRPC Command Panel, I get a "System Internal Error" alert. The Apache error log then says: [Mon Jun 06 10:48:41.459377 2022] [php7:notice] [pid 22322] [client 192.168.xxx.xxx:45030] socket bind failed: No such file or directory, referer: http://deb11srv1-kamailio/siremis/sipadmin/jrcmds The path siremis/… [View More]

t_cancel_callid - doesn't insert Reason header, if called from branch 0
by Pavel Veselovsky 07 Jun '22

07 Jun '22

Hallo all, I defined branch_failure routing block via t_on_branch_failure() In the branch_failure route, in case of "408 Request timeout" I am sending CANCEL with reason "t_cancel_callid("$ci", "$cs", "22", "408")". If the t_cancel_callid("$ci", "$cs", "22", "408") is called in branch_failure for branch idx 0, the CANCEL is sent, but Reason header is missing there. Why? (I expect that t_cancel_callid() should insert Reason header regardless of branch it is called from) If the … [View More]

SNMP, export concurrent calls count
by ZZ Wave 30 May '22

30 May '22

Hello. Debian 10, Kamailio 5.2.1 I want to monitor concurrent calls in/out per every trunk connected to this proxy (it's done with dialog profiles), and export this to Zabbix. But I can't find in snmpstats documentation how to export user-defined variables. Help me please. Maybe SNMP isn't the best solution for that...
