Via header force change protocol to TLS?

by Anthony Alba

I have kamailio behind a TLS termination proxy so the sockets are correctly deduced to be TCP. However the clients only talk TLS to the proxy and are confused when the top Via header added by Kamailio is TCP. Is there a way for Kamailio to forcibly pretend its protocol is TLS? Like advertised_address but "advertised_protocol" instead. (With pjsip testing: it has a flag use_tls which ignores TCP from Kamailio and continues to use the persistent TLS transport to proxy. Linphone fails because it tries to honor TCP in Via and is unable to establish TCP transport). BTW I am using t_relay_to_tcp so Kamailio will return traffic to the proxy as TCP even though the contact addresses specify transport=TLS.

Dialog and DMQ on restart

by Björn Klasen

Hi everybody, I'm just testing Kamailio 5.4.1 with dialog replication over DMQ. This seems to work very good. Dialogs are replicated without problems. When I'm restarting one node I would have expected, that all dialogs are synced again, just like in dmq_usrloc. But this does not happen. After a restart the nodes dialog-list is empty. Did I miss somethin? Is there a special parameter that I have to set?

Upgrade Minor versions

by Gavin Baumanis

Hi there, I have taken over a project that uses Kamailio. I am aware of what we use it for - I am just not sure on the how... apart from what I have read in the docs. We're currently running 5.4.2 and I'd like to upgrade to (at least) the latest 5.4 offering - as that seems as if it would be the easiest and safest option. So I am hoping I might get some direction, please - on the way forward for an upgrade. The documentation seems OK if you're upgrading minor versions... but I couldn;t find anything about upgrading patch versions. Thanks!

Updated: Online devel meeting on matrix - 15:00 UTC, Dec 5, 2023

by Daniel-Constantin Mierla

Hello, we should consider an online devel meeting sometime soon to summarize what was done at (and still needs to be done after) devel meeting in Dusseldorf and plan a bit the targets for next major release (5.8 or 6.0)? If considered useful, I propose Dec 5 at 15:00UTC (16:00 Berlin/Paris/Madrid/Rome), but we can also look for other dates as well. Topics to be discussed can be added at: - https://github.com/kamailio/kamailio-wiki/blob/main/docs/devel/irc-meetings… Pull requests can be made by users without git access. Cheers, Daniel PS: Previous announcement indicated the start time 14:30 UTC, this message changes it to 15:00 UTC - 30min later due to a constraint in availability of one of the Kamailio developers. -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda

Setting up Kamailio as SIP Proxy

by Saul Ibarra

Hi, I am needing some help setting up kamailio as a sip proxy between a provider(trunk) and a test pbx The trunk requires username&password and i would like to add that information to the request within the Kamailio proxy, so that the PBX can authenticate directly by IP (without username&password) through the Kamailio proxy. As a programmer with a limited background in SIP (currently learning), I am keen on understanding the intricacies of this setup at the SIP level. Could you please direct me to resources or documentation that covers scenarios similar to mine? Any help or guidance you could provide would be greatly appreciated. Thanks

tsilo dependency on usrloc

by Alex Balashov

Hi, I wanted to revisit the topic of tsilo dependence on the location service. All three ts_append*() functions have the following quality: - ts_append(): "performing a contact lookup on the table specified by the domain parameter." - ts_append_by_contact(): "the contact lookup is performed" - ts_append_to(): "performing a contacts lookup on the table specified by the domain parameter" Why is this extensive coupling to usrloc necessary? This makes it impossible to use `tsilo` in case of providing a push-notification add-on that front-ends an upstream registrar, requiring a kind of local shadow registrar or mid-registrar. What would make more sense is a generic mechanism that allows one to "drip" new contacts into an existing transaction, whether suspended or active. Kamailio has a mechanism to add more branches to an existing transaction, but the scope of that mechanism is only from *inside* the vantage point of the transaction in question. The key parlour trick of `tsilo` is that it permits dripping new branches into a *different* transaction. ts_append_to() almost does the trick, providing a target index and label, but it just insists on doing a registrar lookup to source the contacts. What is really wanted and needed for the downstream PN gateway use-case is a means of extracting contacts from incoming registrations (or other sources, potentially) without storing them in any fashion locally, without using or even loading usrloc, and just throwing them over the fence into a different transaction. Is this somehow possible by means other than tsilo? Am I overlooking something?

How to use: kamcmd ul.db_users?

by Benoit Panizzon

Hi List I want to find a way to check how many users are regsitered. https://www.kamailio.org/docs/modules/devel/modules/usrloc.html#usrloc.r.db… But no matter how I try, I get a 500 error... # kamcmd ul.db_users location And yes, the table is called 'location'. I did try to find out how kamctl ul show --brief pulls that information, but did not succeed. Also that command takes way too long how that we have several thousand registered users. Or would I need to query this directly from the database?

No access to variables within timer route

by dries＠degendt.com

Hi, I have a timer which is called each 5 seconds: modparam("timer", "declare_timer", "REFRESH_CALLSTATE_TIMER=REFRESH_CALLSTATE_TIMER,5000,slow"); I'm enabling setting the variable "testvar" and enabling the timer when an INVITE is received: if (is_method("INVITE|ACK|UPDATE|CANCEL|BYE")) { $var(testvar) = "blablabla"; timer_enable("REFRESH_CALLSTATE_TIMER", "1"); ... route[REFRESH_CALLSTATE_TIMER] { xlog("L_INFO", "Testvariable: $var(test)\n"); } However, the variable is always 0: INFO: <script>: Testvariable: 0 I've also tried printing pseudovariables like $ci, $du but nothinh seems accessible. Is there a workaround for this? Best regards, Dries
