Connection at same Port

Hello ,
we are 2 friends connecting everyone at 5060 port and it is working as expected.
Now for example if the number of user is for example 100, then how everyone will be connecting to same port 5060. ?
Is there is any internal thread has been configured by default? or manually there is any method to increase the thread?

Please advice

If you are referring to UDP there is no connection, it just receives SIP messages and sends them out. There’s nothing to configure for the thread, except to ensure UDP is enabled.
