Without Enhancements

Without the enhancements configured, the Oracle Communications Session Border Controller’s surrogate agent performs a series of registrations based on count when the system boots or when its configuration changes. It only attempts to register each user once. Although the surrogate agent uses the same retry mechanism used for SIP client transactions, it does not attempt further if it receives a failure response until the entry expires. When it receives 401, 403, or 407 responses to requests that include authentication, the surrogate agent’s automatic incrementing mechanism appends a number to the end of each registered username. Always starting at one, this number cannot appear in any other position in the username.
