Hello Daniel, substr you suggested didn't worked. See my previous email.
your previous email didn't say anything about the results. That's why I asked. Be sure you don't have those spaces that are in the email you wrote. Also, I had more parenthesis in the parameter of the subst_uri().
Or you can try the alternative with:
if($rz=="sips") { $ru = "sip" + $(ru{s.substr,4,0}); }
I asked for more details from the backtrace to confirm that what I found is the cause for the crash in this case -- see one of my previous emails from today.

I tried something like
if (proto==TLS) { #subst_uri('/^sips.+)$/ sip:\1/ '); subst("/sips:/ sip:/g "); }
but there some cases where client use ;transport=TLS which need remove too.

change the r-uri to use sip instead of sips.
You can try with:
subst_uri('/^sips:(.+)$/ sip:\1/ ');

You don't need to run kamailio through gdb. If it crashes, then you get a corefile -- in the logs it says the name of the file. It is usually located in / or in the path you gave to -w parameter.
After you reproduced the crash, locate the corefile and run gdb like:
gdb /path/to/kamailio /path/to/corefile bt full
The /path/to/kamailio should be /usr/sbin/kamailio if you installed from rpms.
If you have improvements to init or sysconfig kamailio file, send a patch and we will include the changes in kamailio repository.

Hello,
looking at the logs, the process routing the register is forwarding it, by opening a tls connection -- that is because the uri has sips as schema.
The crash is reported in another process that doesn't print much logs messages. As Olle suggested, can you get the backtrace with gdb from the core file? That will help to see where the crash happened.
gdb /path/to/kamailio /path/to/corefile bt full
And again, it would be good to upgrade to 4.2.3 -- it is same config and database, just install new version and restart. In this way we rule out issues that were fixed already, avoiding to spend time on something fixed.

Hello,
can you send the REGISTER request received by kamailio and your config to me?
As you receive it over TLS, you can get the register by adding the next line in kamailio.cfg at the beginning of request_route:
xlog("received request: [[$mb]]\n");
I will like to double check if the issue is still present.
You should upgrade to 4.2.3, because it is the latest stable, you have 4.2.1 and there were many fixes meanwhile.
If you preserve sips as uri schema, then you force tls further for forwarding. You should change that to sip:domain ...

Hello Everyone, I have standard case where kamailio play role of proxy for asterisk servers. Kamailio configured use TLS transport on public side and on private side UDP 5060. When client (SIP soft phone) connect to TLS socket everything goes well until kamailio trying forward request. Kamailio tries DNS resolve tls transport srv records instead of udp then it just crashed when no tls configured on private side of kamailio.
Do I need manually fix sips in URI ? Or some different miss configuration ?

This is clearly not a valid sip uri.
/O
Hello,
your substitution to replace sips with sip all over the message is breaking it. Use only the part I gave for r-uri, the rest should left untouched, so don't use the subst(...).
See this message again for what I asked from backtrace:

Hello Daniel, substr you suggested didn't worked. See my previous email.your previous email didn't say anything about the results. That's why I asked. Be sure you don't have those spaces that are in the email you wrote. Also, I had more parenthesis in the parameter of the subst_uri().
Or you can try the alternative with:
if($rz=="sips") { $ru = "sip" + $(ru{s.substr,4,0}); }
I asked for more details from the backtrace to confirm that what I found is the cause for the crash in this case -- see one of my previous emails from today.
