External Mobility

Mobility functions for employees working not from the office but mobile are enabled either by the IP Office Power User or the IP Office Mobile Worker license. The former Mobile Twinning / Mobility License will continue to work with all the features described below.

The mobility functions enabled by these user licenses are Mobile Twinning , and Mobile Call Control , as well as one-X Mobile client support . Each feature has to be enabled in IP Office Manager for eligible users.

Mobile Twinning (External Twinning)

A typical use for Mobile Twinning would be for a salesperson that has a desk extension but is often out of the office. They only give out their office phone number to clients, but the IP Office Mobile Twinning will ring their mobile/cell phone as well as the desk extension. External mobile devices can be set as twinning targets even if the primary telephone is logged out (e.g. in the case of a "virtual" extension).

Call Back

To avoid any call charges when using a mobile / cell phone the call back feature has been implemented:

When calling a particular number at the IP Office, the IP Office will reject the call and will call back the mobile number if this number has been identified as an eligible one. After accepting this call the mobile user gets a dial tone and can establish another call. Depending on the service provider’s tariff, there are no call charges (except possible roaming charges) on the mobile invoice.

This feature is very useful for employees using their personal mobile phone for business only from time to time: their personal mobile phone number stays confidential and they do not to claim mobile charges back from their business.

Avaya one-X Mobile Client Support

IP Office supports the Avaya one-X Mobile 'Single Mode' Clients running on selected Symbian Single-Mode or Windows Mobile 5 or 6.x handsets. This provides a graphical interface for call control and allows a one-number service for both incoming and outgoing calls.

For a full list of supported handsets see

IP Office systems supporting one-X Mobile require a dedicated DID/DDI number for each feature required (e.g. hold, transfer).

Mobile Call Control

This allows a user who has answered a twinned call on their mobile/cell phone to dial a DTMF sequence ** (star-star) to put the call on hold and receive IP Office system dial tone. The user will then be able to perform supervised and un-supervised transfers, shuttle (switch between held calls), and conference (Conference add and transfer to a meet-me conference).

Mobile Call Control is a mobility feature similar to but independent of one-X Mobile. It allows any mobile phone user to access IP Office features without using the one-X Mobile client application.

Mobile users can gain access to the “Star Star Service” dial tone when they receive a twinned call. After receiving a twinned call, the mobile user can dial ** to place that call on hold and get dial tone from the IP Office. Once the mobile user receives IP Office dial tone, any subsequent dialing done is interpreted as if the user is logged into an analog extension on the IP Office.

To gain access to the “Star Star Service” dial tone, the mobile user can dial the FNE 31 DID/DDI that has been programmed in the IP Office. Similarly, once dial tone is heard, the user can dial numbers and short codes as if the user is logged into an analog extension on the IP Office.

Mobile Call Control and one-X Mobile require twinned calls to be routed through specific trunk types on IP500 / IP500v2 only:

IP500 PRI-U (single or dual) daughter cards
IP500 Dual or Quad BRI daughter cards
SIP trunks (RFC 2833)

IP Office Softphone

Usable both inside the office and at remote locations, IP Office Softphone is a PC-based telephony client allowing a user to make and receive phone calls right from his PC, equipped with e.g. a headset of speakerphone. In addition, the softphone supports end to end Video between two softphone users on a IP Office network. Full voice access to the IP Office system is available wherever reliable access to the company network exists.

This can be in meeting rooms, using a Voice ready Wi-Fi network, at a remote office site using the local Ethernet interface or at home or in a hotel-room, when connecting to the company network through a VPN (Virtual Private Network).

The softphone offers standard calling functionality, like several call appearances, hold, transfer and access to a large number of IP Office features via dedicated feature keys. Access to IP Office directory is of course also available.

IP Office Softphone can be used as a standalone client (not requiring any additional server) or in combination with one-X Portal for IP Office.

If used in combination with the one-X Portal application, the softphone delivers a centralized call log, synchronized with many IP Office telephones as well as a number of collaboration features like presence status indication and instant messaging. one-X Portal can be used with the standard deskphone while working in the office and switched to softphone when working remote.

Details about IP Office Softphone can be found in the chapter User Call Control Applications .

Mobile Messaging

Mobile Messaging means managing your voice messages together with email messages using the mobile / cell phone. Similar to a unified messaging solution on the desktop PC it enables the user to manage all of their daily messages in one place, in this case the mobile messaging application of the mobile / cell phone (like for example Outlook Mobile on Windows Mobile devices).

At the low end of the range of mobile messaging options is the simple voicemail-to-email forwarding using SMTP, which is standard with both the Essential and Preferred Edition.

The synchronization of the voice message status between all a user’s devices (Outlook, voicemail telephone interface, one-X Portal, mobile / cell phone) so that listening to a new message at one device changes the message status from “new” to “old” in all of these interfaces requires the Preferred Edition. It contains an IMAP interface to integrate the VoiceMail Pro solution with any IMAP capable email system.

With the IP Office Preferred Edition in conjunction with an Exchange 2007 Server it is possible to synchronize received voice mails with the email system. If the email system also empowers mobile users to receive, manage, and send messages by their mobile phone (‘Mobile Email’) all voice mails can be managed as well from the mobile / cell phone.

Together with an appropriate mobility solution like Blackberry the Exchange 2007 integration enables visual voicemail on mobile devices. The voice mails provided by the Preferred Edition are specially marked as “voicemail” so Exchange 2007 handles them different from standard emails so that a mobility solution will be able to show voice mails on the display of the mobile device. Users can now browse through the voicemails, identify high priority ones by caller information and listen to them first.
