htable event routes behavior
by Володимир Іванець 25 Sep '18

25 Sep '18

Hello all, I have following configuration: 1. Htable which loads from MySQL DB and has autoexpire setting. *modparam("htable", "htable", "tl_connect_users=>size=4;autoexpire=120;dbtable=some_htable")* 2. Regular *route[SOME_ROUTE]* with sole logic. 3. *event_route[htable:mod-init]* 4. *event_route[htable:expired: some_htable]* I use while loop in *event_route[htable:mod-init]* to extract stored values from htable, assign them to *$var(some_variable)* and call *SOME_ROUTE* to perform some action for all of them on Kamailio start up. *SOME_ROUTE* has *$sht(some_htable =>$var(some_variable)) = "enabled"* line to add expired value back to the htable. The pboblem is when* event_route[htable:expired: some_htable]* triggers *SOME_ROUTE*. Values are not being added to htable. Hovewer if I will try to manipulate values for key_name or key_value by adding some character new item will be insert to the htable. Does anybody know if behavior is correct when exactly same value can not be inserted back to htable on it's expired event? Thanks a lot!

Help with kamailio/freeswitch
by David Villasmil 25 Sep '18

25 Sep '18

Hello guys, I know this is kamailio's mailing list, but I'm getting no answer on freeswitch, and i thought someone here has probably done this is the past. I have a proxy in front of freeswitch. I want freeswitch to use the proxy for everything including the termination to my provider. If I configured the gateway like this: <include> <gateway name="myprovider"> <param name="username" value="username" /> <param name="auth-username" value="username"/> <param name="password" value="password" /> <param name="register" value="true"/> <param name="caller-id-in-from" value="true"/> <param name="from-domain" value="myprovider.com"/> <param name="realm" value="myprovider.com"/> <param name="register-proxy" value="myproxy.domain.com"/> </gateway> </include> The registration works properly, the REGISTER goes to the proxy like REGISTER sip:myprovider.com;transport=udp SIP/2.0 and the proxy forwards it fine, and registration works great. But when i try to call via this gateway, the call goes STRAIGHT to the provider! If, on the other hand, i configure my gateway as: <include> <gateway name="myprovider"> <param name="username" value="username" /> <param name="auth-username" value="username"/> <param name="password" value="password" /> <param name="register" value="true"/> <param name="caller-id-in-from" value="true"/> <param name="from-domain" value="myprovider.com"/> <param name="realm" value="myprovider.com"/> <param name="register-proxy" value="myproxy.domain.com"/> <param name="proxy" value="myproxy.domain.com"/> </gateway> </include> Registration does NOT work, because the uri is: REGISTER sip:myproxy.domain.com;transport=udp SIP/2.0 Because there is no registrar on that proxy!

24 Sep '18

Greetings, I'm using subst_hf() function to do some search and replace and i want to identify a undifined amount of digits after a string (ex: string=123123). Everywhere i look, the right way seems to be \d so i'm doing subst_hf("Via","/;string=\d/substitution_string/", "a"); It doesn't seem to work. Any ideas why? Best Regards, Duarte Rocha

Issuse with http_client and config_file
by Barry Flanagan 24 Sep '18

24 Sep '18

Hi I am trying to use http_client with a config_file set but can't get it to work .Have tried on 4.4 and 5.1 with the same results (Debian 9 packages). Here are my modparams modparam("http_client", "config_file", "/etc/kamailio/httpconnections.cfg") ..and here is the contents of httpconnections.cfg [apiserver] url = https://my.api.com/v1 username = apiuser password = api_password timeout = 1 authmethod = 2 maxdatasize = 4 tlsversion = TLSv1.2 verify_peer = yes Whenever I try to run this, I get the following error: http_client [curlcon.c:142]: curl_get_connection(): curl_get_connection no success in looking for httpcon: [apiserver] I am running the folowing: $var(res) = http_connect("apiserver", "/wlrmap/$var(wlrUserFromPAI).json", "$avp(wlrdata)"); >From the debug logs it appears that Kamailio is initialising the module OK (included below) so I am not sure why it is failing to find it subsequently.

Module RTPPROXY param Timeout_Socket not Working

Kamailio didn't start listening on IP mentioned in Module RTPPROXY parameter Timeout_Socket<https://kamailio.org/docs/modules/5.1.x/modules/rtpproxy.html#rtpproxy.p.ti…>. Below is my configuration file. loadmodule "rtpproxy.so" modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722") modparam("rtpproxy", "rtpproxy_tout", 1) modparam("rtpproxy", "rtpproxy_retr", 2) modparam("rtpproxy", "timeout_socket", "xmlrpc:http://127.0.0.1:8000/RPC2") loadmodule "xmlrpc.so" modparam("xmlrpc", "route", "XMLRPC"); modparam("xmlrpc", "mode", 1) modparam("xmlrpc", "url_match", "^/RPC2") when I type a command $ netstat -nlp it only shows SIP listening ports.

uac usage
by David Villasmil 21 Sep '18

21 Sep '18

Hello guys On my working config, i enabled uac like so: loadmodule "uac.so" ... modparam("uac", "reg_db_url", DBURL) modparam("uac", "reg_db_table", "uacreg") modparam("uac", "reg_contact_addr", "test-proxy.singlecomm.com") ... And i added a user to the uacreg table: id,l_uuid,l_username,l_domain,r_username,r_domain,realm,auth_username,auth_password,auth_ha1,auth_proxy,expires,flags,reg_delay 1,10001,myuser,test-proxy.test.com,myuser,myprovider.com,myprovider.com ,myuser,mypass,,sip:myprovider.com,300,0,0 But it's not trying to register, and when i do: #> kamcmd uac.reg_info l_uuid 10001 I get: error: 404 - Record not found What am I doing wrong?

Include parameters in replies
by Duarte Rocha 21 Sep '18

21 Sep '18

Greetings, I need to to include some routing information (Two Id's, example "id_in=10;id_out=72") to be read later by Kamailio in every Request (Except the first one and in every Reply. For the requests, i'm including this info as parameters in the Record-Route and i'm reading it later in the Route Headers. For replies i thought about using the Via header. I'm using subst_hf() and i'm having success adding the parameter to Via in the requests. However, it does not seem the best idea since i breake the routing when i add the parameter. I wanted to avoid using custom headers for this since i can't really be sure that they won't be erased by any client's CPE or endpoint. Any ideas on this ? Thanks Cheers, Duarte Rocha
