1.3.5.3 One Number Service (ONS)
The One Number Service (ONS) effectively makes mobile phones operate as fixed network
extensions. This means that subscribers can be reached under their OpenScape Business phone
number world-wide and can identify themselves only by their respective fixed network numbers.
The mobile phone integration with the One Number Service offers a single phone number for the
workplace (system telephone) and the mobile phone. The caller dials the system phone's number
(fixed network). Outgoing calls from mobile phones are signaled to the called party with the fixed
network number. Another advantage of the One Number Service is the system- and network-wide
busy indicator for the mobile subscriber.
1.3.5.4 Dual-Mode Telephony
Dual-mode mobile phones support both GSM/UMTS networks and WLAN networks. Registration
at the communication system as a SIP station is possible over a WLAN.
If the dual-mode mobile phone is in the WLAN range, it is automatically called as a SIP station
(SIP features). If it is outside the WLAN range, the dual-mode mobile phone is called via
GSM/UMTS (i.e., mobile phone integration functionality is available).
Automatic forwarding to the GSM phone number only works if the associated SIP station is
entered in the system as a mobile phone station (mobile phone integration). This means that if
the SIP station is registered, it is called as a SIP station, and if it is not registered, it is called via
the GSM phone number assigned in the mobile phone integration configuration. CTI call features
are not available for SIP clients in myPortal for Mobile. Call control usually occurs within the SIP
clients instead (see also the Release Notice and http://wiki.siemens-enterprise.com).
Calls on the company premises occur over the WLAN. As long as calls are made via a SIP client,
no call charges are incurred on the mobile phone. Handover and roaming are supported within
the WLAN range (if the wireless LAN infrastructure is designed for it), but not from WLAN to
GSM, and vice versa.
1.3.5.5 Desk Sharing
With Desk Sharing, multiple subscribers can share a system telephone and thus a workplace.
With Desk Sharing (or Hot Desking), subscribers have no fixed workplace and no fixed office
phone. Desk Sharing enables multiple mobile subscribers of the communication system to share
an office workplace and/or the phone. The subscriber simply logs in at the workplace phone
where he or she happens to be currently working. After the login, the phone number of the
employee is assigned to the used phone, and all programmed functions, as well as any
associated VM and the UC features become available.
Desk Sharing is implemented via Mobile Logon or, for only the next outgoing call, via
Flex Call/Mobile PIN.
If Desk Sharing is to be implemented for IP telephones (HFA) in networked nodes, an external
DLS (Deployment Service) must be installed. For TDM phones, Desk Sharing can be
implemented via Relocate (also called Hoteling). The following features can be used with Desk
Sharing:
– Speaker call (paging)
– Conferencing
– Override
– Toggle/Connect
– Parking
– Consultation
– Transfer
– Call pickup
– Do Not Disturb
– Call forwarding
– Send message (message waiting)
