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,

dlg_req_within kamailio 5.7 CSeq values
by Jonathan Hunter 16 Nov '23

16 Nov '23

Hi All, I am playing around with the dlg_req_within to send a REINVITE to toggle some rtpengine parameters and this works fine. The first time I use the command after tracking the dialog, it sends a REINVITE with an incremented CSEQ value. However when I issue it again, it sends another REINVITE but with the same CSEQ value, so again 2 for example. How can you ensure its incremented or can you set it somehow? As would like to generate at least 2 reinvites per dialog. Many thanks Jon Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows

How to check for presence of a file from a route? (Or any other way to tell kamailio not to accept new calls)
by Benoit Panizzon 13 Nov '23

13 Nov '23

Hi I'm still looking for a better way to tell Kamailio that we want to enter 'maintenance' and STAY in maintenance after a restart. Maintenance is: Reject all messages without totag with 503 to prevent creating new dialogues. I could use a shared pv and the use kamcmd pv.shvSet to toggle it. But when kamailio is restarted, that pv is also reset to it's initial state. Not good, if I want to make sure the node stays in maintenance mode after a restart as for example after pushing a config change via ansible. So what comes to my mind is to check for the presence of a file. something like: route[CHECK_MAINTENANCE] { if (!has_totag() && is_method("INVITE")) { if (file_exist("/etc/kamailio/maintenance.flag")) { xlog("L_ERR", "Maintenance flag present! Rejecting INVITE\n"); t_send_reply("503", "Maintenance mode - no new calls accepted"); exit; } } } Mit freundlichen Grüssen -Benoît Panizzon- -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

Inconsistent behavior between reg_fetch_contacts (registrar module) and reginfo_handle_notify (pua_reginfo module)?
by Mohammad Hossein Ahmadi 13 Nov '23

13 Nov '23

Hello everyone, I have previously set up Kamailio 5.7.2 IMS configuration (including P-CSCF, S-CSCF and I-CSCF) and successfully made voice calls. Now I'm trying to set up an IP-SM-GW AS using the example here (with some tweaks): https://github.com/kamailio/kamailio/blob/master/src/modules/smsops/example… Currently I'm trying to send the SMS using a SIP software client (MicroSIP). The problem is, while the SMS is received at the AS and stored in the database, it does not send it to the callee. While troubleshooting the problem, I've found that reg_fetch_contacts("location", "$var(uri)", "caller") in route[SEND_SMS] cannot find the contact which was added by reginfo_handle_notify("location") in route[NOTIFY] in the usrloc database. By tracing the problem more, I've found that reginfo_handle_notify (when handling reg event NOTIFY) adds the complete AoR in the "username" field in the location table, e.g. as "bob(a)ims.mnc001.mcc001.3gppnetwork.org". But reg_fetch_contacts (when trying to send the SMS) looks up the table using only the user part in the "username" field, e.g. "bob". So it cannot find the callee contact and the configuration assumes the callee is still not registered; so it tries to send out a SUBSCRIBE every time it tries to send an SMS to the callee, instead of actually sending the SMS. Does anybody have any idea on what could have caused this inconsistent behavior between reginfo_handle_notify and reg_fetch_contacts?

Dispatcher list reloading itself from file?!?
by Benoît Panizzon 13 Nov '23

13 Nov '23

Hi List I wanted to take one of our cores down gracefully by not destroy running dialogues to be able to implement a config change on Kamailio 5.5 For this I did: kamctl dispatcher.remove ID SIP-URI, for every IC This worked fine, Kamailio is instructed to reply 503 on out of dialogue traffic from unknown endpoints causing the endpoints to re-route traffic to the other core, eventually making it possible to stop and restart Kamailio without harm. dialog count was steadily decreasing, until after about 10 minutes after removing the dispatcher URI's it started to increase again. kamctl dispatcher.list shows me, all dispatcher URI I removed are back! There is no ds_reload() being executed by calls. In the module description, I find no hint, that the dispatcher config is being reloaded from file in some interval or so. What could be the cause of my removed dispatcher suddenly being back? -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

pseudo variable in include_file not possible
by Bernd Krueger-Knauber 13 Nov '23

13 Nov '23

Hi, since we use git also for our kamailio stuff, we need to check in also host specific stuff. (same kamailio.cfg but different addresses and ... ) For this I thought an include_file for different hosts would be nice, but I can not check in the different host specific files, because I can not use something like: |include_file "$HN(n).cfg" It is not allowed in kamailio 5.6.x Or better: the pseudo variable is not replaced. Is there a way to work arround, or is it possible to make it possible? Best regards Bernd |
