[OpenSIPS-Users] Limits for dialog profiling

[Răzvan Crainea]

Hi, John!

The only limitation of the dialog profiles that I can think of is that 
the counter cannot exceed the maximum value of unsigned int (4294967295).
Yes, dialog profiles can be used to count the number of active calls 
with a specify "key" (as you require, the key can be a destination 
number), even though there are thousands of concurrent calls.
The log_profile_hash_size is used to define the Hashtable size. The 
larger the hashtable is, the fewer hash collisions you have. It does not 
limit the number of profiles at all, it only affects the performance of 
the hashtable. You can find more information here[1].
