[SR-Users] Critical dialog - Bogus event 5 Problem - PRACK after 200OK

[Daniel-Constantin Mierla]

Hello,

it should be safe, the prack doesn't change the state of the dialog 
after it is established (state 4). If you see some side effects, report 
them here.

Perhaps the log message should be adjusted a bit. What version are you 
using (kamailio -V)?

Cheers,
Daniel
