1. When SBC is the refresher, the configuration item, ‘Terminate on refresh failure’ does not apply,  That is, anytime the session timer fires the SBC will send either a re-Invite or Update.
2. When Peer is the refresher (Not SBC), the following applies:
   a. If ‘Terminate on refresh failure = false’, SBC will send a re-Invite or Update on session timer fire.
   b. If ‘Terminate on refresh failure = true’, SBC will terminate the call by sending a BYE when the session timer fires.
   • Set the timer value is as follows:
     • Set timer X seconds before the session expires, where X is the smaller value of 32 or 1/3 of the session timer value.
       Example: Session timer = 180, then X=32 since 32 is less than 60. Then, timer will be set for 180-32 = 148 seconds.
