[OpenSIPS-Users] how to debug new opensips setup

[Bogdan-Andrei Iancu]

Hi Erik,

if you set in your cfg "debug=6", you will get a very verbous output of 
opensips to the log file.  So, if any package is received, you should 
see it by the logs.

1) do you see the opesips startup logs ?

2) do you see any new logs when sending packages to opensips ?

Regards,
Bogdan
