TLS capture with sip_trace()
by Mikko Lehto 13 Jan '15

13 Jan '15

Hi I am getting incorrect source port to Homer web while tracking outgoing request from my proxy to remote SIP server. Juha Heinanen <jh(a)tutpro.com> wrote in another thread: > in case of tcp (and tls) the source port is always a random one. > only the destination port can be predetermined. Interface capture (tcpdump) shows exactly what Juha wrote i.e. random source port for TLS connection. I always get local TLS listener address as Homer source_port, clearly not true when comparing to output of tcpdump. I am calling sip_trace() from branch_route and onsend_route. Is it even possbile to use siptrace with TLS so that it records correct TCP (random) source port to Homer? I tried briefly printing some structure variables in siptrace/siptrace.c but it seems that real source port is not available in struct dest_info at that context. -- Mikko

Maxmind GeoIP2 implementation.
by Sergey Okhapkin 12 Jan '15

12 Jan '15

Is anybody working on implementation of geoip2 module for kamailio? The advantage of the new API is a seamless support of both ipv4 and ipv6 addresses. If there is no work in progress, I'm goild to take the duty to implement module geoip2 based on the existing geoip module. I don't think it worth to extend geoip module to support both maxmind database formats.

Problem with tag field with using a custom table for the permissions module.
by Jan Hazenberg 09 Jan '15

09 Jan '15

Hi, I'm trying to use a custom table for the permissions module and run into a issue with the tag field, all other fields seem to work fine. Here is my config: modparam("permissions", "db_url", DBURL) modparam("permissions", "db_mode", 1) modparam("permissions", "peer_tag_avp", "$avp(permissions_tag)") modparam("permissions", "trusted_table", "trunks") modparam("permissions", "source_col", "ip") modparam("permissions", "proto_col", "transport") modparam("permissions", "from_col", "from_pattern") modparam("permissions", "tag_col", "trunk_uuid") When i start kamailio i see the following error in the log: Jan 6 21:49:57 sip /usr/sbin/kamailio[24327]: ERROR: db_mysql [km_dbase.c:123]: db_mysql_submit_query(): driver error on query: Unknown column 'trunk_uuid' in 'field list' Jan 6 21:49:57 sip /usr/sbin/kamailio[24327]: ERROR: <core> [db_query.c:132]: db_do_query_internal(): error while submitting query Jan 6 21:49:57 sip /usr/sbin/kamailio[24327]: ERROR: permissions [address.c:112]: reload_address_table(): failed to query database Jan 6 21:49:57 sip /usr/sbin/kamailio[24327]: CRITICAL: permissions [address.c:363]: init_addresses(): reload of address table failed Jan 6 21:49:57 sip /usr/sbin/kamailio[24327]: ERROR: permissions [permissions.c:631]: mod_init(): failed to initialize the allow_address function Jan 6 21:49:57 sip /usr/sbin/kamailio[24327]: ERROR: <core> [sr_module.c:968]: init_mod(): Error while initializing module permissions (/usr/lib/x86_64-linux-gnu/kamailio/modules/permissions.so) Jan 6 21:49:58 sip kamailio: ERROR: <core> [daemonize.c:315]: daemonize(): Main process exited before writing to pipe If i change the tag_col to tag it works fine, both fields are varchar(64). And the field trunk_uuid exists in the trunks table. I'm running kamailio 4.2.1 Thanks, Jan Hazenberg

dialog timeout reinvite
by Kelvin Chua 09 Jan '15

09 Jan '15

Happy new year everyone! :) I have stumbled into a case where a switch would send a reinvite to my kamailio server every 15 minutes. I am setting dialog timeout using avp for prepaid purposes. now i think it resets the timer upon processing of the reinvite. what is the best way to work around this?

listening to specific interface with ip
by Jijo 09 Jan '15

09 Jan '15

HI All. I know that kamailio support listen on an interface with port (listen = eth0:5060). Does it support listen on an interface with ip, port, transport? For example listen=eth0: udp:10.10.10.10:5060 Thanks Jijo

Can you use the sr.modf() method / function to call append_branch?
by J Lee 08 Jan '15

08 Jan '15

I would like to know if there's a way to do parallel forking via lua code. So specifically, I'd like to be able to do something like this: seturi("sip:a@example.com"); append_branch("sip:b@example.com"); append_branch("sip:c@example.com"); append_branch("sip:d@example.com"); t_relay(); except via lua, because the list of branches is dynamic. I've tried the following: sr.modf("append_branch","sip:10.x.x.x") but the error message I'm getting is: /usr/sbin/kamailio[7437]: ERROR: app_lua [app_lua_sr.c:177]: lua_sr_modf(): function 'append_branch' is not available Just wondering if I "should" be able to do this. I've been reading http://www.kamailio.org/wiki/embeddedapi/devel/lua#srtm_package but haven't seen any references to append_branch. The other alternative I'm looking at is to just use lua to generate the list of destinations and pass back a hashtable of sorts to the cfg file. Then from there I will try to loop through the hashtable and do the append_branch command for each entry in the table. If you have other suggestions, I'd appreciate it. Thanks.
