Voice over IP (VoIP) VoIP System Telephones After restart, the logged out Aastra 673xi/675xi will show a login page. A user can enter his call number and his user PIN. If a device entry with this call number exists and has the same device type, the login procedure continues. If the device entry is currently active on another device, the associated remote Aastra 673xi/675xi will be logged out automatically and will show a login page on its part. The now logged in Aastra 673xi/675xi starts and will get its configuration from the newly assigned device entry. Note: When adding the device entry, it is also possible to activate the Logged out option. 9.5 VoIP System Telephones The following telephones and software packages are available for VoIP system telephony: ■ Aastra 6773ip (OpenPhone 73 IP): This is a VoIP-enabled edition of the Aastra 6773 (OpenPhone 73) system telephone.
