The final user has two different kinds of credentials, both supplied by its client administrator:
User portal access credentials
SIP credentials used to register terminals to IvozProvider
Through the user portal, it can browse their call registry and configure:
Call forward
Do not disturb
Call waiting
Displayed data when calling
Geographical configuration
On the other hand, the SIP credentials allow users to configure their terminals to place and receive calls.
Note
The same SIP credentials can be used in multiple devices at the same time,generating what is known as parallel-forking: whenever a call is placed to an user, all the active devices will ring so the user can answer the call from any of them.
