Changes to the SIP message headers are not visible immediately, see:

https://www.kamailio.org/wiki/tutorials/faq/main#why_changes_made_to_headers_or

If it would be inside request_route, then you would be able to use msg_apply_changes(), but in this case you can just look at what is sent out and Contact should be there. Being over TLS, you can use modules like sipdump or siptrace to view the incoming/outgoing SIP traffic.

You are interested in advertised_port probably

Please note, SIP RFC allow not to send port if that port is 5060 udp.

QUESTION

Is there any way to answer a call or originate a call by Kamailio?

Asked 2021-Mar-01 at 05:51

I know that Kamailio works as a SIP Proxy and I also know that Asterisk/FreeSWITCH or other similar products can do what I'm asking here, but still wondering if it's possible to use Kamailio to answer a call or originate a call?

Let's say, "User ---> Kamailio", Kamailio answer the call with "200 OK to INVITE", and then play an announcement "Thank you for using Kamailio", then BYE the call?

I can't find any related information so I guess the answer is no, but still want to double check.

Many thanks in advance.

Answered 2021-Feb-27 at 22:59

You can answer and play message if you use kamailio with mediaproxy.

Mediaproxy docs have some samples.

Originate is problematic and unreasonable in most cases, but there is https://www.kamailio.org/docs/modules/devel/modules/rtimer.html

Much simple method is use SIPP or perl/python sip module(external), after that rewrite call in kamailio as you wish.

Problem is that in your config your serial forking route runs before looking into Kamailio location DB. So after first fork to 1001@192.168.50.131 you need somehow to route call to part where Kamailio looks into location DB, in default config it is route(LOCATION). Something like this:

QUESTION

How to get Kamailio to set `Record-Route` header to internal IP for internal leg of call?

Asked 2020-Sep-07 at 13:42

I have Kamailio 5.4.1 (and RTPEngine) running on an internal server with a private IP address 172.31.7.96 and One-to-one NAT to an external IP address. The external IP is 192.0.2.100. (Note: The internal IP addresses are all unedited, but the public IPs have been replaced with TEST-NET-1 and TEST-NET-2 example addresses.) I will eventually be doing transcoding with RTPEngine, but for now this is a simple SIP Proxy.

I have a Java application that sets up SIP calls running on an internal server with a private IP address 172.31.7.171. The Java application has set properties.setProperty("javax.sip.OUTBOUND_PROXY", "172.31.7.96"); to use Kamailio as an outbound SIP proxy.

The Kamailio server is a stock Kamailio sample configuration with the following changes:

To resolve such an issue I switched to use IPv6 on internal SIP servers for signaling and IPv4 for RTP media.

Sounds like an error with the SQL INSERT query, if I had to guess I'd say you're being caught out by the date format in the SQL table not matching the date format you're pushing to it.

I don't know the structure of your database, but there's a simple trick I use for debugging SQL queries when I can't see the query being run;

Start up Wireshark/TCPdump on the machine and packet capture for all SQL traffic (MySQL is port 3306) and replicate the error. From the packet capture and you'll be able to see the Query Kamailio's database engine ran.

QUESTION

Are Kamailio pseudo-variables $var safe to use until the end of a single message handler?

Asked 2020-Mar-25 at 19:35

I'm using pseudo-variables $var in Kamailio because according to the documentation, they are faster than $dlg_var, but I'm wondering if it's safe to use them like this:

ANSWER

Answered 2020-Mar-10 at 03:47

Values of $vars variables cleared at the start of new message loop.

So for the single message, it is safe.

Kamailio run X threads(configurable in config/at startup), the main loop send each message to one of threads. That way processing can go concurent and use all CPUs.
