Configuration settings

The following settings are used to set the system's voicemail server type and location. Fields are enabled or grayed out as appropriate to the selected voicemail type. Refer to the appropriate voicemail installation manual for full details.

These settings can be edited online with the exception of Voicemail Type and Voicemail IP Address. These settings must be edited offline and requires a reboot of the system. To enter offline editing, select Menu Bar Current User Icon > Offline Mode.

Voicemail Type

Field

Description

Voicemail Type

Sets the type of voicemail service used by the IP Office server.

None

No voicemail operation.

Analogue Trunk MWI

Select this option to support receiving a message waiting indicator (MWI) signal from analog trunks terminating on the ATM4U-V2 card. MWI is a telephone feature that turns on a visual indicator on a telephone when there are recorded messages.

Avaya Aura Messaging

Select this option if you want to configure the system to use Avaya Aura Messaging as the central voicemail system. If you choose this option, you are still able to use Embedded Voicemail or Voicemail Pro at each branch to provide auto-attendant operation and announcements for waiting calls. When selected, access to voicemail is routed via an SM line to the numbers specified in the AAM Number field. The optional AAM PSTN Number can be configured for use when the SM Line is not in service.

For a setup where the voicemail box numbers configured on Avaya Aura Messaging or Modular Messaging are same as the caller's DID, the short code to route the PSTN call should be such that the caller-id is withheld ( "W" in the telephone-number of the shortcode ). This is to make sure that, during rainy day - the voicemail system does not automatically go to the voicemail box of the caller based on the caller id.

Call Pilot

Select this option if you want to configure the system to use CallPilot over SIP as the central voicemail system. If you choose this option, you are still able to use Embedded Voicemail or Voicemail Pro at each branch to provide auto-attendant operation and announcements for waiting calls. When selected, access to voicemail is routed via SM line to the numbers specified in the CallPilot Number field.

  • The CallPilot PSTN Number field and associated Enable Voicemail Instructions Using DTMF check box are not supported. IP Office cannot access the CallPilot system over the PSTN when the Session Manager line is down.

  • Users can access their CallPilot voicemail by dialing the Voicemail Collect short code. Access to CallPilot voicemail from Auto Attendant cannot be enabled by setting a Normal Transfer action to point to the Voicemail Collect short code. If desired, it can be enabled by setting a Normal Transfer action to point to the CallPilot number.

Centralized Voicemail

Select this option when using a Voicemail Pro system installed and licensed on another system in a multi-site network. The outgoing line group of the IP Office line connection to the system with the Voicemail Pro is entered as the Voicemail Destination.

In a Server Edition network this option is used on the Secondary Server and expansion systems to indicate that they use the Primary Server for as their voicemail server.  

Distributed Voicemail

This option can be used when additional Voicemail Pro voicemail servers are installed in a SCN network and configured to exchange messages with the central voicemail server using email. This option is used if this system should use one of the additional servers for its voicemail services rather than the central server. This option is not supported by Server Edition systems.

When selected:

  • The Voicemail Destination field is used for the outgoing H.323 IP line to the central system.

  • The Voicemail IP Address is used for the IP address of the distributed voicemail server the system should use.

Embedded Voicemail

IP500 V2 systems can store voicemail messages and prompts on the system's own memory card. It also supports internal auto-attendant configuration. For details, refer to IP Office Embedded Voicemail Installation.

Group Voicemail

This option is used to support third-party voicemail systems attached by extension ports in the group specified as the Voicemail Destination. Not supported by Server Edition systems.

Modular Messaging over SIP

Select this option if you want to configure the system to use Modular Messaging over SIP as the central voicemail system.

  • When selected, access to voicemail is routed via an SM line to the numbers specified in the MM Number field.

  • The optional MM PSTN Number can be configured for use when the SM Line is not in service.

Remote Audix Voicemail

Select this option if using a remote Avaya Intuity Audix or MultiMessage voicemail system. Requires entry of an Audix Voicemail license. This option is not supported by Server Edition systems.

Voicemail Lite/Pro

Select this option when using Voicemail Pro. The IP address of the PC being used should be set as the Voicemail IP Address.  In a Server Edition network this option is used on the Primary Server.  It can also be used on the Secondary Server if the Secondary server includes its own voice mail server. Use of Voicemail Pro requires licenses for the number of simultaneous calls to be supported.

Field

Description

Voicemail Mode

Default = IP Office Mode.

This field is only shown here for Embedded Voicemail. For systems using Voicemail Pro, it can be changed using the Default Telephony Interface setting shown in IP Office Web Manager and the Voicemail Pro client.

Voicemail provided by the IP Office system can use either IP Office Mode or Intuity Mode key presses for mailbox functions. End users should be provided with the appropriate mailbox user guide for the mode selected. You can switch between modes without losing user data, such as passwords, greetings, or messages.

The following user guides are available from the Avaya support web site:

  • Using IP Office Embedded Voicemail Intuity Mode

  • Using IP Office Embedded Voicemail IP Office Mode

  • Using a Voicemail Pro Intuity Mode Mailbox

  • Using a Voicemail Pro IP Office Mode Mailbox

Voicemail Destination

SIP Settings

For Embedded Voicemail and Voicemail Pro, for calls made or received on a SIP line where any of the line's SIP URI fields are set to Use Internal Data, that data is taken from these settings. These options are shown if the system has SIP trunks and is set to use Embedded Voicemail, Voicemail Lite/Pro, Centralized Voicemail or Distributed Voicemail.

Field

Description

SIP Name

Default = Blank on Voicemail tab/Extension number on other tabs.

This value is used for fields, other the Contact header, where the SIP URI entry being used has its Contact field set to Use Internal Data.

  • On incoming calls, if the Local URI is set to Use Internal Data, the system can potentially match the received R-URI or From header value to a user and/or group SIP Name. This requires the SIP URIs Incoming Group to match a Incoming Call Route with the same Line Group ID and a . (period) destination.

SIP Display Name (Alias)

Default = Blank on Voicemail tab/Name on other tabs.

The value from this field is used when the Display field of the SIP URI being used is set to Use Internal Data.

Contact

Default = Blank on Voicemail tab/Extension number on other tabs.

The value is used for the Contact header when the Contact field of the SIP URI being used for a SIP call is set to Use Internal Data.

Anonymous

Default = On on Voicemail tab/Off on other tabs.

If the From field in the SIP URI is set to Use Internal Data, selecting this option inserts Anonymous into that field rather than the SIP Name set above. See Anonymous SIP Calls.

Voicemail Language Prompts

When the system routes a call to the voicemail server it indicates the locale for which matching prompts should be provided if available. The locale sent to the voicemail server by the system is determined as show below. If the required set of prompts is not available, the voicemail will fallback to another appropriate language and finally to English (refer to the appropriate voicemail installation manual for details).

  • Short Code Locale: The short code locale, if set, is used if the call is routed to voicemail using the short code.

  • Incoming Call Route Locale: The incoming call route locale, if set, is used if caller is external.

  • User Locale: The user locale, if set, is used if the caller is internal.

  • System Locale: If no user or incoming call route locale is set, the system locale is used unless overridden by a short code locale.

Systems using Embedded Voicemail, if the required set of upgraded language prompts to match the locale is not present on the system SD card, Manager will display an error. The required prompt set can be uploaded from Manager using the Add/Display VM Locales option.
