Obsoleting unmaintained modules
by Daniel-Constantin Mierla 21 Nov '23

21 Nov '23

Hello, during the Kamailio Developers Meeting 2023 in Dusseldorf that took place last week, it was proposed to obsolete modules that seem to be unmaintained and no activity about them was noticed during the past years. It is quite some overhead in packaging them and trying to keep them compiling when they have external dependencies, therefore such step should spare some resources in the future. The list (see below) was built based on the options of those present at the meeting, now we want to discuss it on the larger communities of developers and users. If you are using any of these modules or you think any of them worth keeping, reply with the names of the modules that you want to be kept. The proposed action is to relocate the obsoleted modules to a new git repository "kamailio-obsolete" to still keep some visibility to them and in the eventually of future interest on any of them, it can be reintroduced in the main repository. Next is the initial list of modules proposed to be considered obsolete: - app_java - app_lua_sr - app_mono - app_python - app_sqlang - auth_identity - call_control - db2_ldap - db2_ops - db_cassandra - db_perldvdb - dnssec - domainpolicy - h350 - mediaproxy - osp - peering - print - print_lib - pua_xmpp - ratelimit - uid_auth_db - uid_avp_db - uid_domain - uid_gflags - uid_uri_db - uri_db - xmpp - xprint Cheers, Daniel -- Daniel-Constantin Mierla (@ asipto.com) twitter.com/miconda -- linkedin.com/in/miconda Kamailio Consultancy and Development Services Kamailio Advanced Training -- asipto.com

UAC DNS SRV timeout
by Sergiu Pojoga 17 Nov '23

17 Nov '23

Hi, Setup: kamailio acting as a UAC needs to register with a server whose outbound proxy is DNS SRV based only, there's no A record on the proxy's FQDN. The provider advertises two SRV records. ;; ANSWER SECTION: _sips._tcp.sip.provider.com. 10 IN SRV 10 50 5061 sip11-sip.provider.com. _sips._tcp.sip.provider.com. 10 IN SRV 15 50 5061 sip10-sip.provider.com. Everything was working fine, until the provider changed the SRV priority, putting a lower priority on the host that is actually down at the moment. In this case, sip11-sip.provider.com is DOWN and sip10-sip.provider.com is UP. Now, what's happening is Kamailio tries to REGISTER with the lower priority host, gets no reply back (TCP connection doesn't get established). It then takes 30 seconds for Kamailio to try the host with the higher priority, registering successfully. And so it goes for every re-register: failure => 30 seconds => register OK. The same happens for INVITES to the downstream: INVITE => timeout => 30 seconds => INVITE (other host 200 OK). I've tried to play with TCP and DNS params, but so far no luck: no matter what I did - it took the same 30 seconds for Kamailio to detect failure and retry the secondary host. Any suggestions will be highly appreciated. Kamailio 5.6.4 (x86_64/linux) 239d0a tcp_connection_lifetime=3604 tcp_max_connections=60 tcp_connect_timeout=10 tcp_keepalive = yes tcp_crlf_ping=yes tcp_keepcnt=3 tcp_keepidle=30 tcp_keepintvl=30 tcp_reuse_port=1 tcp_accept_no_cl=yes tcp_rd_buf_size=16384 use_dns_cache = on use_dns_failover = on dns_srv_loadbalancing = on dns_try_naptr = on dns_try_ipv6=no dns_try_naptr=no dns_use_search_list=no dns_retr_time=1 dns_retr_no=3 Thanks --Sergiu

auth_check : sip user / authentication user mismatch
by Jawaid Bazyar 17 Nov '23

17 Nov '23

Hi, I am trying to register an endpoint as follows: REGISTER sip:siptest.booger.net SIP/2.0 Via: SIP/2.0/UDP X.X.X.X.76:31114;branch=z9hG4bK223420485;rport From: sip:1720XXXXXXX@siptest.booger.net;tag=962873337 To: sip:1720XXXXXXX@siptest.booger.net Call-ID: 2053687751-32761-1(a)EH.BJI.BAE.HG CSeq: 2067 REGISTER Contact: sip:1720XXXXXXX@X.X.X.X:31114;reg-id=2;+sip.instance="<urn:uuid:00000000-0000-1000-8000-000B82A1C58B>" Authorization: Digest username="654fe87c-67ff-42dd-8d5e-79786a99713c", realm="siptest.booger.net", nonce="ZVaJtmVWiIrsuWc5hkzM3MUUUs8MgRFR", uri=sip:siptest.booger.net, response="119a3b6426cdcfa037bf1825b69139a5", algorithm=MD5 X-Grandstream-PBX: true Max-Forwards: 70 User-Agent: Grandstream GXP2170 1.0.11.64 Supported: path Expires: 120 MAC: 00:0b:82:a1:c5:8b Allow: INVITE, ACK, OPTIONS, CANCEL, BYE, SUBSCRIBE, NOTIFY, INFO, REFER, UPDATE, MESSAGE Content-Length: 0 Note that the Authorization username differs from the To-From username. This is intentional, as I am testing use of randomly generated credential . This worked with this endpoint directly against Asterisk, for instance. However, registering against Kamailio now, I am getting: Nov 16 21:24:26 vs-rs01 /usr/sbin/kamailio[584855]: DEBUG: {1 2067 REGISTER 2053687751-32761-1(a)EH.BJI.BAE.HG} auth_db [authorize.c:503]: auth_check(): authentication username mismatch with from/to username Even though I have this set in the config: if (!auth_check("$fd", "subscriber", 0)) { // default 1, change to 0 to skip check 0 is supposed to mean no user checks performed. I am doing this because I want to use the complex credentials for authentication, but want the endpoint to tell me the phone number in an INVITE to/from, instead of putting in the extremely long credential. Is there a way to get Kamailio to accept different SIP User ID and Authentication ID fields? Thanks, Jawaid

pv cache limit is going to be exceeded
by Ali Taher 17 Nov '23

17 Nov '23

Hello all, I'm using the following Lua script to fetch data from Redis, which is in form of list: function split(str, delimiter) for token in string.gmatch(str, "[^" .. delimiter .. "]+") do return token end end function contains(mainString, subString) return string.find(mainString, subString, 1, true) ~= nil end function longest_match_acode() local currentSeconds = os.time() local milliseconds = os.clock() * 1000 local ddate = os.date("%Y-%m-%d %H:%M:%S", currentSeconds) .. string.format(".%03d", milliseconds) KSR.xlog.xinfo("starting date:" ..ddate) local size = 0 local result local acode = "29192" local inputbcode = "4474173" local delimiter = ":" while size == 0 do local currentSeconds = os.time() acode = string.sub(acode, 1, string.len(acode) - 1) KSR.ndb_redis.redis_cmd("srvN", "LRANGE price:" .. acode .." 0 -1", "r") size = tonumber(KSR.pv.get("$redis(r=>size)")) end local left = 0 local right = size - 1 while left <= right do local currentSeconds = os.time() local milliseconds = os.clock() * 1000 local ddate = os.date("%Y-%m-%d %H:%M:%S", currentSeconds) .. string.format(".%03d", milliseconds) resultRight = tostring(KSR.pv.get("$redis(r=>value[" .. right .. "])")) resultLeft = tostring(KSR.pv.get("$redis(r=>value[" .. left .. "])")) local bcodeLeft = split(resultLeft, delimiter) local bcodeRight = split(resultRight, delimiter) if contains(inputbcode, bcodeRight) then KSR.xlog.xinfo("Input bcode contains bcode value from Redis: " .. resultRight .. " at index: " .. right .. " with date: " .. ddate) end if contains(inputbcode, bcodeLeft) then KSR.xlog.xinfo("Input bcode contains bcode value from Redis: " .. resultLeft .. " at index: " .. left .. " with date: " .. ddate) end left = left + 1 right = right - 1 end local currentSeconds = os.time() local milliseconds = os.clock() * 1000 local ddate = os.date("%Y-%m-%d %H:%M:%S", currentSeconds) .. string.format(".%03d", milliseconds) KSR.xlog.xinfo("ending date:" ..ddate) end function ksr_request_route() if KSR.is_INVITE() then longest_match_acode() KSR.sl.send_reply("404", "Not found"); end end I'm getting the following warning in the log : WARNING: LUA {INVITE}: <core> [core/pvapi.c:340]: pv_cache_add(): pv cache limit is going to be exceeded - pkg memory may get filled with pv declarations I think the issue is in the following lines: resultRight = tostring(KSR.pv.get("$redis(r=>value[" .. right .. "])")) resultLeft = tostring(KSR.pv.get("$redis(r=>value[" .. left .. "])")) the list coming from Redis has around 30k items, which I'm iterating through using value[x] which is exhausting the pv declaration as per my understanding. How to overcome this issue? Is it possible to save the list as an array variable and then iterate through that array? Regards,
