[SR-Users] dlg_end_dlg

[Daniel-Constantin Mierla]

Hello,

the backtrace shows that the process is blocked inside perl script 
listing on the network. Perhaps is waiting the reply to the command sent 
to kamailio. Perhaps the perl functions you are using in your script can 
have a timeout and not block forever.

In which case you need to terminate the call in config? There is a 
dlg_bye() function that could be useful.

Cheers,
Daniel
