TCP Persistent Connections
by Ross McKillop 10 Nov '21

10 Nov '21

Hopefully the collective hive mind can help with this one, as I have little experience of using TCP in this manner and neither does a friendly Kamailio expert I know personally. I'm replacing a closed box thing that accepts connections from various nodes over TCP. They send INVITEs and REGISTERs over that TCP socket and expect to receive inbound calls over the same established TCP socket. Struggling to make Kamailio behave the same way, but it should be possible. The first time it receives a message, I add the sender to the dispatcher as follows; jsonrpc_exec('{"jsonrpc": "2.0", "method": "dispatcher.add", "params": [5, "sip:$si:$sp;transport=tcp", 0, "socket=tcp:127.0.0.1:5776"], "id": 1}'); This works great, but despite setting the socket to use there, when a call later comes in and it's routed to one of the dispatcher nodes that's been added in this way it fails because Kamailio attempts to open a new connection to the IP / PORT rather than having kept the socket open from the earlier message and reusing the same connection/. Any ideas? I get the feeling I'm missing something obvious! Ross

$var assignment broken on master ?
by Chaigneau, Nicolas 09 Nov '21

09 Nov '21

Hello, I've just built Kamailio from the master. Assigning a value to a < var > doesn't seem to work anymore... This works with Kamailio 5.5.2. E.g. : $var(my_var) = "hello"; xlog("L_WARN", "var(my_var): $var(my_var)\n"); # => This shows value 0. Regards, Nicolas.

How to determine size (number of elements) in xavp stack?
by Benoît Panizzon 09 Nov '21

09 Nov '21

Dear Community In my previous post I mentioned my problem with sql_xquery I fear I used this wrong. $dbr is probably only populated if sql_query is used. Anyway, it is always 0 in my testings, even if I clearly get a result. Now I would like to know how many results I have. How can I determine the size of an $xavp stack (or array)? Or is there another way to get the number of rows returned by a sql_xquery without looping an index through all rows? -- 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 ______________________________________________________

sql_xquery return 1 on 0 rows?
by Benoît Panizzon 09 Nov '21

09 Nov '21

Dear List... kamcmd> version kamailio 5.4.7 (x86_64/linux) Strange issue found. According to: https://kamailio.org/docs/modules/5.4.x/modules/sqlops.html I should get return value 2 if no rows returned: $var(query) contains a query that does not match (number is not assigned) if (sql_xquery("impkam", "$var(query)", "assignedtn") == 1) { if ($avp(debug) > 1) { xlog("L_INFO", "$cfg(route): SQL Dump Result: $var(assignedtn) ROWS: $dbr(assignedtn=>rows) \n"); } do stuff with the assigned number } else { do stuff in case that number is not assigned } Log Output: CHECK_ASSIGNED_TN: SQL Dump Result: 0 ROWS: 0 So the return value of the query was == 1 but the result contains no rows. How can that be? -- 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 ______________________________________________________

STIR/SHAKEN public key
by David Villasmil 05 Nov '21

05 Nov '21

Hello guys, I'm testing with 2 providers right now, and one of them is asking me to include my whole certificate on the *secsipid_add_identity(origTN, destTN, attest, origID, x5u, keyPath)* like: *secsipid_add_identity("$fU", "$rU", "A", "", "https://kamailio.org/stir/$rd/cert.pem <https://kamailio.org/stir/$rd/cert.pem>", "/secsipid/$rd/key.pem");* but it is stated that: *x5u is the HTTP URL referencing to the public key that should be used to verify the signature;* One provider is asking to put the cert there, the other hasn't asked that yet. So i'm a little confused, should the x5u be the actual cert (with its intermediary?) or only the public key? Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

Suppressing part of the xlog line
by Steve Wilkins 05 Nov '21

05 Nov '21

Hello, Is there a way to suppress the printing "date & time, host, and Kamailio execution path" at the begging of each xlog line? Example current xlog line: Nov 4 16:54:52 myserver /usr/local/sbin/kamailio[7021]: INFO: <script>: => Test xlog line I would like xlog line to be: INFO: <script>: => Test xlog line Thank you,

Is this idea even feasible?
by Antony Stone 04 Nov '21

04 Nov '21

Hi. I'm looking for a solution to the following problem, and wondering whether Kamailio (with which I have very little experience so far) may be it, or whether I'm thinking in totally the wrong direction. The problem: I have a SIP client application which runs on a standard Linux system, and is extremely basic - it can REGISTER in order to receive inbound calls, and it can send INVITEs in order to place outbound calls, and that's about it. It handles media as well - in essence, it's a simple softphone. I can't change it for a more capable one, before anyone suggests that :) Specifically, this thing cannot send REINVITEs in order to put calls on hold, nor can it handle anything to do with transfers (blind or attended). I'm looking for something which does have these SIP capabilities which I could put in between this application and the SIP server through which it is placing and receiving calls, so that I can (through some sort of API) cause calls in progress to be put on hold, resumed, blind transferred, or hold-and-attended- transferred. Does that sound like something Kamailio can do? If so, can anyone point me in a helpful direction re how to go about it? If not, can anyone suggest something else which could sit in between a very basic SIP client and a PBX server, in order to inject these sorts of commands into the path and thereby give me these sorts of extra call capabilities? Thanks, Antony. -- I'm not impossible, just highly implausible. Please reply to the list; please *don't* CC me.

STIR/SHAKEN, is a number format mandatory?
by David Villasmil 04 Nov '21

04 Nov '21

Hello guys, I'm getting failed by my provider because I'm sending to them with +1 both on the headers and on the payload. My understanding is there is no mandatory format, or is there? Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337
