Configure SIP timers

Information for configuring the Timer B the timeout for receiving INVITE replies setting

Overview

SIP timers have an effect on the functional configuration of the product. You can configure Timer B, the timeout in milliseconds for receiving a reply from a client after the SIP container sends an INVITE request to that client.

If a SIP container does not receive a reply from a client after the defined Timer B timeout value, the container sends error message 408 to the application.
