TCP Session Timer Setting for VOIP system on Cisco ASA 5515

[WestlakeIT]

I'm setting up our Cisco router to for best practices for a new VoIP system we're adopting (8x8).  I've got most things figured out, but I wanted to verify whether my thoughts are correct or not on on particular thing.  The guide for setting up a Cisco 5505 for this service (only guide they had and close enough to the 5515) has this entry when talking about timouts:

• TCP session timer (TLS connections only, port 5443): 300 - 700 seconds

Looking it up, it seems the default TCP timeout timer is an hour, so this isn't something I need to worry about, right?

if one side send (FIN,ACK) the Conn will immediate end and not wait idle TCP timeout 
if not in any case then ASA wait TCP idle timeout and end Conn.
