Mediant 1000 & Mediant 600
The maximum permissible size of the file is 10,800 bytes for Mediant 1000 analog modules
and 108,000 bytes for digital modules.
Each PBX extension registers separately (a REGISTER message is sent for each entry
only if AuthenticationMode is set to Per Endpoint) using the IP number in the From / To
headers. The REGISTER messages are sent gradually. Initially, the device sends requests
according to the maximum number of allowed SIP dialogs (configured by the parameter
NumberOfActiveDialogs). After each received response, the subsequent request is sent.
Therefore, no more than NumberOfActiveDialogs dialogs are active simultaneously. The
user name and password are used for SIP Authentication when required.
The calling number of outgoing Tel-to-IP calls is first translated to an IP number and then (if
defined), the manipulation rules are performed. The Display Name is used in the From
header in addition to the IP number. The called number of incoming IP-to-Tel calls is
translated to a PBX extension only after manipulation rules (if defined) are performed.
