With additional licence: Skill-based routing and/or sender-based routing

Time-controlled after-work switchingA stored announcement can be played back on a time-controlled basis or diverted to a voice mailbox.
Fixed call forwarding

The administrator can activate call forwarding for a group

  • Call forwarding immediately
  • Call forwarding by time (group drop, takes effect even if no user is logged on to the group)
  • When busy (group overflow, takes effect when all users logged on to the group are busy)
IVR system

Time-controlled end-of-work switchingA stored announcement can be played back on a time-controlled basis or redirected to a voice mailbox.
ClipNoScreeningServer-based definition of outgoing phone numbersThe sender numbers defined by the administrator can no longer be changed by the user.
This function must be supported by the SIP trunk.
User configurationDefine telephone keysFunction keys can be defined for the user.
Define skillsSkills can be entered for a skill-based queue.
SIP trunk and phone numbersFree configurationAll providers approved by STARFACE can be connected:
Administration of voice services - web admin - lines
RoutingIf several SIP trunks are connected, the routing can/must be set up.

System connection

The extension number must have at least 2 digits.
If there are several external lines, the extension areas must not overlap.
Multi-device connectionThe last 2 digits are entered as the internal extension number. If there are several external lines, the DW ranges must not overlap.
Emergency callSTARFACE Connect used as the SIP trunkIf STARFACE Connect is used as a SIP trunk with ProCall NEX, the addresses under which phone numbers are booked are automatically stored in the STARFACE Control Center. In the event of an emergency call, the caller is automatically routed to the relevant control center in the address range.
Different SIP trunk (not STARFACE Connect)For all other SIP trunks, a line (trunk) must be defined in the PBX via which the emergency calls (e.g. 110, 112) are routed to the exchange. 
Emergency numbersThe emergency numbers (e.g. 110, 112 in Germany) are reserved in the PBX so that they can be routed directly to the exchange.
These can therefore not be assigned as internal numbers for a subscriber.
