Forward Registration
by nutxase 28 Jun '23

28 Jun '23

Hi All I have setup kamailio using websockets(wss) i am trying to forward any registration that comes to kamailio to go to asterisk, so in theory kamailio is a registration proxy i have set rewritehostport("xxx.xxx.xxx[:5080](http://node3.sipalto.com:5080)"); the registration forwards fine but the contact on asterisk side shows as sip:xxx:kamailioip.xxxx.invalid so therefore asterisk sees the sip peer as offline what am i missing :( Sent with [Proton Mail](https://proton.me/) secure email.

Matching the From Username in LCR rule table
by harneet singh 27 Jun '23

27 Jun '23

Hi Experts, We wished to used the LCR Module to be able to select the Gateway(s) to send the calls to based on the From(Caller) Username. Based on the LCR Documentation, the usage of other fields like request URI or prefix etc is pretty clear. But for the From Usename I am having certain trouble understanding the same. It refers to some mtree. Excerpt below: "A gateway matches a request if user part of Request-URI matches "prefix", caller URI matches "from_uri" pattern,* caller URI userpart matches mtree with "mt_value"*, and callee URI matches "request_uri" pattern in a tuple that is associated with the gateway." Can someone explain/ share a sample lcr_rule table entries for the From Username that can be matched against the incoming sip message for gw selection? Do we need to manually create an mtree by the name "*lcr*". Asking based on the below section in LCR documentation? Any pointers are highly appreciated. 3.35. mtree (string) Name of mtree to which load_gws() matches caller URI userpart. *Default value is "lcr".* Regards, Harneet Singh -- "Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth" - Sir Arthur Conan Doyle

uac_replace() and uac_restore debug help
by Duarte Rocha 24 Jun '23

24 Jun '23

Hello, I'm currently experiencing some odd behaviours when using these functions and I need some help debugging to find the root of the issue. I receive a call from a client and do some changes to the To and From header using auto mode with password. Encrypted info goes on the Record-Route header parameters (vsf\vst) normally. 1 - On subsequent requests sent by the originating client, domains on To and From header are different from the ones sent in the first INVITE. In this scenario, somehow the automatic modifying has errors on the end result. Can the different domains affect the end result of the automatic modifying or only the vsf\vst parameters and password are needed to the auto replace\restore? 2 - How can I decrypt the info on vsf and vst parameters in order to verify the info sent and the encryption? Cheers, Duarte Rocha

uac_restore behaviour question
by Duarte Rocha 22 Jun '23

22 Jun '23

Hello, I have some questions regarding uac_replace methods. When I receive the first INVITE from someone I change To and From using uac_replace_to() and uac_replace_from(). I do this only on first INVITES. In order to restore them I use the "auto" so the changes are restored automatically in replies or requests sent to the call originator.. In the case of subsequent requests from the originator kamailio still changes To and From without me using uac_replace functions. Is this caused by the auto restore? Does it work for both sides and is this is the intended behaviour? Cheers

How to handle 302 redirects
by Trey Ormsbee 22 Jun '23

22 Jun '23

Hello, Im having a hard time figuring out how to handle a 302 reidrect, the uac_redirect modules shows a simple configuration. However for me, what it is not doing is changing the 302 back to invite. It is sending the 302 as is on. if(!t_check_status("3[0-9][0-9]")) { exit; } get_redirects("3:1"); t_relay(); This code just relays the 302 for me. I should add I am using this with the DISPATCHER module so perhaps that has something to do with my issue. Setup is this, kamailio is sitting between to sip servers, so the flow goes like this, sip_server_a -> kamailio -> sip_server_b. sip_server_b only responds with 302 redirects, sip_server_a does not handle 302’s at all. Kamailio will only get invites from sip_server_a, and the redirects from sip_server_b will only have one contact. How can I get kamailio to reply to sip_server_a’s invite with the updated INVITE? My config is a mesh of the dispatcher example and uac_redirect example with this specific section handling the redirect: # Sample failure route failure_route[RTF_DISPATCH] { xlog("L_NOTICE", "RTF_DISPATCH: "); if (t_is_canceled()) { exit; } # next DST - only for 500 or local timeout if (t_check_status("500") or (t_branch_timeout() and !t_branch_replied())) { if(ds_next_dst()) { t_on_failure("RTF_DISPATCH"); route(RELAY); exit; } } if (t_check_status("302")) { xlog("L_NOTICE", "RTF_DISPATCH: 302 "); if (!get_redirects("1:1")) { xlog("L_NOTICE", "RTF_DISPATCH: failed to get_redirects "); t_reply("480", "Temporarily Unavailable"); exit; } xlog("L_NOTICE", "RTF_DISPATCH: got redirects "); t_relay(“sip_server_a”,”5060”); } } Any ideas what I am doing wrong is this supported? Im expecting once I relay this message that it should be an INVITE not a 302 redirect. I cant find any examples of anyone else really doing this.

Hello, I have the following statement: if KSR.is_method("INVITE") then KSR.log("info", "method not allowed " .. KSR.kx.get_method() .."\n"); KSR.x.exit(); end For some reason, it falls into this condition no matter which method I use, I tried OPTIONS, NOTIFY etc. log file: <core> [core/kemi.c:152]: sr_kemi_core_log(): method not allowed OPTIONS the same with this check: if KSR.is_method_in("I") then KSR.log("info", "method not allowed " .. KSR.kx.get_method() .."\n"); KSR.x.exit(); end this is the lua modparam settings: # ---- lua params ---- modparam("app_lua", "load", "/usr/local/etc/kamailio/main.lua") modparam("app_lua", "reload", 1) modparam("app_lua", "log_mode", 1) cfgengine "lua" version: kamailio 5.7.0 (x86_64/linux) 1c23c2 Any idea what I'm doing wrong?
