This allows customers to connect with other parties by e-mail address as well as
by IP address, as IP addresses may be dynamic and difficult to remember. In
addition, the CS allows customers to connect with other parties by telephone
number through a Voice Gateway which supports the target telephone number.
The Voice Gateway is chosen by the CS based on the E.164 telephone number of
the call.
Processing Calls
When the Voice Gateway routes a call to an e-mail address, the CS is used to
resolve the target e-mail address. And when a Voice Gateway routes calls to a
telephone number, the CS is used to resolve the telephone number to the IP
address of a Voice Gateway which supports the target telephone number.
Maintaining Records
The Voice Gateway, using virtual WebPhone processes, can publish a destination
(such as a conventional telephone) as well as an e-mail address. The CS directs
each call for a virtual WebPhone to the appropriate Voice Gateway for processing.
If the Voice Gateway goes offline for some reason, the status for the related virtual
WebPhone processes are updated by the CS.
Account Management
The Gateway Routing Manager (CS) maintains account information, such as
account type, account number, and PIN code.
Accounts
Accounts can be set up as an individual account or corporate account. All
accounts are identified by an account number and PIN code, and individual
accounts are also identified by an e-mail address.
Transaction Processing
When a Manager (usually the Voice Gateway) requests a transaction, it contacts
the CS for account information. Depending on the type of the account, the CS
either approves or denies the proposed transaction.
