My last name has changed and is incorrect when I make a call, how do I change this?
The source of the information that is displayed on the phone comes from the University's Core User Database (CUD).  The Chorus team cannot update this information manually.  Changes need to be made via your local Personnel team.  Once the change has been made, the information will filter through to the phone display.

In the web portal you will usually see this error if you try to make a call from a preferred device which does not exist.
Why do I have a missed call in my call history with the voicemail symbol but not a corresponding voicemail message?
Voice mail history screen  voice mail screen

There will be a voicemail icon under the Missed call in Call history because the call reached the voicemail part of the system. 

The system detects noise/voice so if the message is silent, no corresponding voicemail will be in the voicemail list.

If a voicemail is recorded and the caller hang ups before pressing #, there will be a voicemail left as the system has detected their voice (the same as if the caller records a message then presses #).


How do I set up voicemail messages?
Visit this page for a guide: Record a new personal greeting.


Does the instant messaging service of Chorus integrate with other IM services, such as Skype or Jabber?
No. Instant messaging requires both users to have a Chorus account.
Can I send instant messages to external clients?
No, this is not currently supported by Chorus.

Preferred devices

Why have I got workphone and a my extension with a one listed in my preferred devices?
By default, accounts are set up to support both a deskphone and a softphone as a preferred device. The deskphone is called 'Work phone', and the softphone is your full telephone number with an additional '1' suffix. If you do not use a softphone, you just need to make sure that your preferred device is set to 'Work phone' when using the web portal to make calls.

Will Chorus work over wireless internet connections, such as Eduroam and OWL?
Your ability to use Chorus on a wireless network is dependent on the quality of your connection, and this depends on various factors such as your location and proximity to wireless access points. We are supporting Chorus over wireless connections on a “best efforts” basis: for best results, you should access Chorus on a computer with a wired network connection.

OSMO for smartphone (iOS, Android)

If I use the OpenScape mobile client to make or receive calls, are there any circumstances in which I will see charges on my mobile phone bill?
Not usually.  However, if you pay for data, then you will see charges as the connections to the client will use data. 
If you are using the Openscape mobile client overseas and you are using Mobile phone (cellular) to receive calls and you are charged for inbound calls to your mobile phone, you will be charged when the client calls your mobile.

Hold music

I don't like the hold music, what should I do?
It is only possible to have one call waiting tone for the whole University. Following complaints that the default call wait tone was inappropriate we replaced the jaunty jingle with the current call wait tone. The current hoopoe call had been used previously on the old Telecoms systems satisfactorily for some years.
Given the diversity of internal and external users, and the constraints of licensing and system, it is unlikely that we will be able to provide something to meet all tastes. A decision was made to use the hoopoe call as a nature sound is preferable to poorly rendered music of any genre.
