| Multi-device connection | The last 2 digits are entered as the internal extension number. If there are several external lines, the DW ranges must not overlap. | |
| Emergency call | STARFACE Connect used as the SIP trunk | If 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 numbers | The 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. | |
