Configuring SIP provider
accounts
In this menu, you can configure SIP
provider accounts and add or delete
incoming call numbers. Log on as SIP
user at a SIP provider with 1 speech
channel (TC system, Cloud,…). In
addition, you are given a central
overview for configuration of the
SIP provider account. SIP provider
accounts link the Access system over
the Internet to the VoIP telephony
connection of a VoIP provider by
means of the Session Initiation
Protocol (SIP).
Note:
After creating an SIP provider
account, you must restart the Access
server services in order to use them.
