A single Session Manager instance installed on geographically distributed servers
System Manager monitors Session Manager's health
System Manager alerts an administrator when it detects a problem
System Manager provides UPS backup for Session Manager in case of electricity loss
System Manager collates system information and logs to help trace problems
The SM100 firewall monitors the rate of incoming SIP messages in order to prevent DOS attacks
At regular intervals, Session Manager sends OPTIONS requests to SIP Entities to check they are still able to receive and process SIP requests
At regular, configurable intervals, System Manager checks the SIP Registry to make sure it is not nearing capacity
Session Manager monitors the types of SIP requests it receives, in order to apply relevant processing
Registration enables calls to be made to their IP phone, thus helping Session Manager avoid costly charges on behalf of the organization
Registration is an IP mechanism for clocking in and out of work
Registration gives Session Manager the user's public identifier and the IP address of the phone, meaning that Session Manager knows where to route incoming calls for the user.
Registration is the mechanism through which User A calls User B, via Session Manager

Timer B was named after Henning Schulzrinne's youngest son
Timer B determines the minimum duration for a SIP transaction, which is by default 32 seconds

Timer B is the time after which a request will be cancelled if a response has not yet been received
True

Session Manager regularly checks the network for unauthorized SIP Entities
The SM 100 card is a self-contained computer that has built-in firewall capabilities
The SM 100 card removes all sensitive information (eg authorization data) from the SIP message before sending it out over the network
Messages are encrypted before being sent over the network and deciphered at Session Manager by the SM 100 card. Only those with relevant keys can decipher the messages

A SIP Domain is an authorized domain from which requests can be accepted
The domain of an incoming Request URI is checked against the SIP Domains collection to determine if the request should be processed locally or simply proxied downstream
An unrecognized SIP Domain causes a request to be challenged
An unrecognized SIP Domain causes a caller to be blocked

They both actively receive network traffic, providing an active / active model of server redundancy
One is for signaling traffic and the other is for management traffic
One belongs to the SM 100 and the other to the server box
The primary adapter receives all network traffic, whilst the secondary is on 'hot stand bye', ready to take over if anything goes wrong with the first
'Originating' and 'terminating' apply to the half call model in which a SIP Entity translates non-SIP signaling on the branch side to SIP signaling on the core side
'Originating' and 'terminating' refers to the SIP Entity in the branch and the SM100 security module respectively
'Originating' and 'terminating' refers to the individual application of features, or services, on behalf of the caller and the callee
