[SR-Users] Dialog Module Hash Size vs Number of Dialogs

Hello,

I am trying to properly size the use of the Dialog Module hash table for
Kamailio 4.1.3 implementation using:

modparam("dialog", "hash_size", <number that is power of two>)

However, in my testing, I have been unable to figure out the relationship
between the hash size and a number of dialogs I need to support.  I think
the hash size is specifying a memory block in kB, but even setting the hash
size to a very tiny number does stop me from creating hundreds of dialogs.

Is there a way to determine a relationship between the hash size and a
rough number of dialogs that would be expected?

Thanks,
