Hi Jurijs,
I had a look at the logs but they are confusing: looks like there are two calls (transactions) stored by tsilo and the ts_append is called only for one.
In the logs you sent:
1) row 19: an INVITE comes with callid 9741c821-93b2-1239-0599-024233fefdc7
2) row 60: since there is no contact the transaction is suspended (transaction hash:id=9467:1575872173)
3) row 132: a REGISTER is received from the user for which the transaction was suspended
4) row 193 onward: the transaction 9467:1575872173 is resumed, the INVITE is sent out and the transaction stored by tsilo
5) row 262: another REGISTER from the same instance (same sip.instance and received) is received
6) ts_append is called but the transaction hash:id is 16864:783220347 and the callid is 3ed4a6c3051ea46b50487a0d1b5b25ec@10.10.0.0: when has this transaction been stored? I couldn't find anywhere in the logs
Which version of kamailio are you using?
Are you setting the "use_domain" tsilo parameter?
First I'd suggest trying to call ts_store specifying the r-uri, as you do for ts_append.
Then could you please retry the scenario being sure that there is only one transaction stored?
Thank you,

Federico

Hi,

Any ideas regarding "t_append_branches(): failure to add branches (-1)"?

Is there a way somehow to dump what ts_append handover towards tm? I think if I would be able to see this I will be able to understand what is wrong. I tried tm:local-request and failure route and branch route, but these routes are not executed when this error happens.

Maybe the issue is that the TLS connection is established between Kamailio and UAC what is in front my Register and this Register kamailio just tries to connect directly towards UAC and it fails? At least this is my idea why this might fail.

Hi Jurijs,
I had a look at the logs and there is something strange: I see the ts_append logs before the registrar module ones (the save function).
Are you sure you are calling ts_append after calling save()?

Hello,

if you get it always, then run with debug=3 and send all the debug messages here, there should be more hints about why a branch is not added.

Hi,

I have several Kamailio proxies - loadbalancer which is used as TLS offload and Authorization server and behind registrar servers.

In this case I can't make tsilo work on the registrar server.

I'm always getting: "tm [t_append_branches.c:172]: t_append_branches(): failure to add branches (-1)"

If I use just one Kamailio which is used as Authorization and Registrar server then tsilo works as expected.

Looks like kamailio where I run ts_append tries to connect to UAC directly and not through Loadbalancer.

Any ideas? How can I troubleshoot this?

Thank you!
