Configuration Examples; Sip Call Flow - AudioCodes Mediant 1000 User Manual

REGISTER messages are sent to the Registrar's IP address (if configured) or to the
Proxy's IP address. A single message is sent once per gateway, or messages are sent per
B-channel according to the parameter AuthenticationMode. There is also an option to
configure registration mode per Trunk Group using the TrunkGroupSettings table. The
registration request is resent according to the parameter RegistrationTimeDivider. For
example, if RegistrationTimeDivider = 70 (%) and Registration Expires time = 3600, the
gateway resends its registration request after 3600 x 70% = 2520 sec. The default value of
RegistrationTimeDivider is 50%.
If registration per B-channel is selected, on gateway startup the gateway sends REGISTER
requests according to the maximum number of allowed SIP dialogs (configured by the
parameter NumberOfActiveDialogs). After each received response, the subsequent
REGISTER request is sent.
