[SR-Users] dlg.end_dlg on RTP timeout

[Daniel-Constantin Mierla]

The xmlrpc module has its own callback, you should not use the one from
xhttp module, see:

  -
https://kamailio.org/docs/modules/5.3.x/modules/xmlrpc.html#xmlrpc.pevent_callback

Try with this one and see if the logs are still there. You may need to
set some other modparams for xmlrpc module if you want to still use
xhttp, so you split the handling based on URL.

On the other hand, I am not sure what causes those error messages, even
when attempting to use xhttp callback, one seems to be trying to get
value of $ci. Do you have topos module loaded? Any other event route
callbacks that you have?

Cheers,
Daniel
