uac_replace_from/to, msg_apply_changes and Re-INVITE

by Henning Westerholt

Hello, I am currently debugging a strange issue related to the usage of uac_replace_from/to() after msg_apply_changes(). It works all fine, but in a Re-INVITE case it inserts the wrong headers for the 100 - Trying case. The calle side gets then a reply with wrong From/To. This happens all the time with this particular cfg. I already checked for the usual issues: - msg_apply_changes() called several times - msg_apply_changes() called after transactions created/async processing etc.. Any ideas what else could be the problem? The msg_apply_changes() is needed for some SDP filtering logic in the cfg. Thanks and regards, Henning -- Henning Westerholt - https://skalatan.de/blog/ Kamailio services - https://skalatan.de/services

Port 5060 omitted in Record-Route

by Lợi Đặng

Hi all, i was using kamailio 4.2.1 located in 2 networks > listen = tcp:MY_ADDR:5060 advertise MY_ADDR:5060 > listen = tls:MY_ADDR:5061 advertise PUBLIC_NAT_ADDR:5061 when the call made from the inside network to out side, running `record_route()` resulted in 2 Record-Route headers added (enable_double_rr=1) Record-Route: PUBLIC_NAT_ADDR:5061;transport=tls;lr > Record-Route: MY_ADDR;transport=tcp;lr That was totally fine omitting the port in the first Record-Route when using tcp (or udp) on the first realm, but when i start switching to tls, it caused trouble Record-Route: PUBLIC_NAT_ADDR:5061;transport=tls;lr > Record-Route: MY_ADDR;transport=tls;lr The client is then told to send ACK/BYE to `MY_ADDR;transport=tls` located at `MY_ADDR:5061` as per rfc3263, then the call would failed. I had another try with `record_route_preset("PUBLIC_NAT_ADDR:5061;transport=tls", "MY_ADDR:5060;transport=tls");`, it really did add what i want with explicit 5060 port on RR, `ACK/BYE` travel on the correct path, but `loose_route()` only consumes the local `Route` header (it should consume 2). So my assumption is to stick with `record_route()` function to make `loose_route()` work properly. I tried using another port on the local realm, e.g: 5062 and the port is explicitly added to the Record-Route header `MY_ADDR:5062;transport=tls;lr` So is `5060` couldn't be explicitly added to the inbound Record-Route, or i just missed something? Any help will be appreciated. P/S: I also tried 4.4.7 and it still omit my 5060 port in the RR. rgds, Loi Dang Thanh Phone : +84. 774.735.448 Email : loi.dangthanh(a)gmail.com

presence_dialoginfo module not sending publish on dialogue change

by Richard Nunley

To whom can be of assistance, I’m am working towards enabling presence on my Kamailio proxy but have hit a bit of a brick wall. I’m seeing dialogues being created and persisted to the database, subscriptions are being handled and rows are being written to the active_watchers table but no PUBLISH is ever being received by the server to kickoff the sending of NOTIFY to the active watchers. Further, I’m never seeing a row in the watchers table though I don’t know that this isn’t expect behavior. I’ve attached my current config for review. Any help will be greatly appreciated! Thank in advance!

db_redis and user

by Joan Salvatella

Hello, We are working on a project that's using two active-active Kamailio 5.2 instances that redirect traffic to several Asterisk 15.4 instances. Kamailio is acting as a registrar and should store the location information of the registered terminals. The backend database is db_redis. Phone terminals get registered and the information gets looked up from the subscriber schema in redis (That's cool) but we are having problems with the locations. This is the related code: modparam("db_redis", "keys", "location=entry:ruid&usrdom:username,domain&timer:partition,keepalive") if(ds_is_from_list("1", "2", "sip:$fd:5080")) { record_route(); route(INVITE_ASTERISK); exit; } route[INVITE_ASTERISK] { xlog("L_INFO", "[R-INVITE-RESOLVER:$ci] Entering ASTERISK INVITE resolver\n"); if (!lookup("location")) { sl_send_reply("404", "User Not Found"); return; } route(INVITE_POSTROUTE); } route[INVITE_POSTROUTE] { rtpproxy_manage(); t_on_reply("MAIN_REPLY"); if(!t_relay()) sl_reply_error(); } When looking up the location schema this errors appear: 9(39) WARNING: db_redis [redis_dbase.c:1098]: db_redis_perform_query(): performing full table scan on table 'location' while performing query 9(39) WARNING: db_redis [redis_dbase.c:1101]: db_redis_perform_query(): scan key 0 is 'expires' 9(39) WARNING: db_redis [redis_dbase.c:1101]: db_redis_perform_query(): scan key 1 is 'expires' 9(39) ERROR: <core> [db_ut.c:92]: db_str2int(): Unexpected characters: [-03-29 18:16:36] 9(39) ERROR: <core> [db_val.c:76]: db_str2val(): error while converting integer value from string 9(39) ERROR: db_redis [redis_dbase.c:1062]: db_redis_convert_row(): Failed to convert redis column 'expires' to db value 9(39) ERROR: db_redis [redis_dbase.c:1231]: db_redis_perform_query(): Failed to convert redis reply for row 9(39) ERROR: db_redis [redis_dbase.c:1243]: db_redis_perform_query(): failed to perform the query 9(39) ERROR: db_redis [redis_dbase.c:1829]: db_redis_query(): failed to do the query 9(39) ERROR: usrloc [udomain.c:981]: udomain_contact_expired_cb(): db_query failed Any hints?

Kamailio v5.2 kamctl alias add problem

by Igor Potjevlesch

Hi kamailios, I meet a problem with the " kamctl alias add" command in the 5.2 version, I saw that the module used to add an alias had changed, and now the command result with an error : [kamailio]# kamctl alias add XXXX@XXXX sip:XXXXX@XXXX { "jsonrpc": "2.0", "error": { "code": 500, "message": "Not enough parameters or wrong format" }, "id": XXXXX } I read the function who return this message " static void ul_rpc_add(rpc_t* rpc, void* ctx)" in the ul_rpc.c in the usr_loc module. I tried to pass the command with two more parameters : # kamctl alias add 0175951068(a)trunk7.bornsip.fr sip:0175951068@trunk7.bornsip.fr NULL NULL { "jsonrpc": "2.0", "result": { }, "id": 29200 } And this time it works correctly, but I saw thaht the test prameters was in the field "path" , do you know why we have to indicate a path ? Are we obliged to indicate this two more parameters ? What is the utility of this field ? Thank you in advance, Igor

by PICCORO McKAY Lenz

recently i wrote a portion of my cfg file but i found that i based my code in other sources and results of try/tach experiments i cannot found the documents for the languaje of the core i only found the link: https://www.kamailio.org/wiki/cookbooks/devel/core but in that link there's no references about languaje per see only about how to write portions of the file and sections.. maybe i wrong or the document are wrote in different way? by example how to evaluate the output of a custom function/section?

app_ruby - KSR::PV.sets method not found

Hi all, I’m trying to set a pseudovariable via app_ruby. I’m able to retrieve pseudovariables using PV.gete as such: However trying to set these using sets, I get “No method found”: KSR::PV.sets("$fu", "sip:#{$uacs[trunk]['r_username']}@#{$uacs[trunk]['r_domain']}") Mar 30 04:44:59 ip-10-0-0-2 /usr/local/sbin/kamailio[28421]: ERROR: {1 102 INVITE 0fae8097312bec2b5ec79ada30c227e7@127.0.0.1:5060} app_ruby [app_ruby_api.c:107]: app_ruby_print_last_exception(): exception: undefined method `[]' for nil:NilClass PV.seti appears to work correctly.
