New and Changed Features

Access Control to LDAP Directory

You can control access to the LDAP directory on the phone. When you configure the phone with an LDAP directory and leave the user credentials empty, the phone prompts for either the username and password or the client DN and password to access the LDAP directory.

If you configure the user credentials in the administrator web interface or in the configuration file, the user can access the LDAP directory without entering credentials.

Call Forwarding Enhancements

The enhancements provide a unified interface for the settings of call forwarding on the phone. The call forwarding has the following modes:

  • Feature key synchronization (FKS)

  • BroadSoft's Extended Services Interface (XSI) Synchronization

  • Local

When you enable the settings for certain call forwarding type (such as, call forward all, call forward busy, or call forward no answer), the corresponding menu items display on the phone screen.

You can enable the call forwarding services in the Supplementary Services section under Voice > Phone on the phone web page.

The settings of call forwarding can be synchronized between the server and the phone by the following ways:

  1. FKS

  2. XSI Synchronization

If you want to make the settings of call forwarding on the local phone take effect, you need to disable FKS and XSI first. The priority of taking effect for call forwarding setting in the supported modes is: FKS > XSI > Local.

Directory Enhancements

The phone now supports the following enhancements:

  • All directories screen: A new phone screen that works as a landing page where users can search contacts from all enabled directories. To enable this feature, use the Browse Mode Enable and Search All Enable fields under the Directory Services section in Voice > Phone of the phone administration web page. Users press Contacts on the phone to access the All directories screen.

    You can also control the maximum number of contacts displayed on the All directories screen. To configure the maximum number, use the Max Display Records field.

  • Category softkey: From the All directories screen, users press the Category softkey to display the Directories screen with all enabled directories. Users can access a directory from the list and perform further operations, such as to search contacts or to make a phone call.


    Note

    The simple search operation for the BroadSoft directory requires XSI actions version 22.0 or later.


  • BroadSoft directory individual mode: This feature toggles the BroadSoft directory mode between the legacy mode and the individual mode. In the legacy mode, only one directory (called "BroadSoft directory") displays on the phone. In the individual mode, you can choose to enable or disable each type of BroadSoft directory and name each type of the directory. If enabled, users can narrow their search to find their contacts quickly in a specific BroadSoft directory.

    To enable this individual mode, use the Directory Individual Mode Enable field from Voice > Phone > XSI Phone Service of the phone administration web page. To manage each type of the BroadSoft directory, use the following fields:

    • Directory Personal Enable and Directory Personal Name

    • Directory Group Enable and Directory Group Name

    • Directory Enterprise Enable and Directory Enterprise Name

    • Directory GroupCommon Enable and Directory GroupCommon Name

    • Directory EnterpriseCommon Enable and Directory EnterpriseCommon Name

Display Caller Number for a Contact with Unresolved Characters

You can configure the phone to display the caller number instead of an unresolved caller name in the incoming call alerts.

By default, the phone displays both the caller name and the caller number in an incoming call alert. If the phone can't resolve the characters in caller name, the user sees boxes in place of the unresolved characters. If you have unresolved characters, configure the phone to display only the caller number with the Replace Unresolved Caller Name with Number field. Locate the field in the Language section on the Voice > Regional tab in the phone web interface.

ICE Implementation on MPP

Implementation of Interactive Connectivity Establishment (ICE) on Multiplatform Phones (MPP) provides the most optimized and direct media path for audio and video calls. Before this implementation, the media path traversed through a cloud-hosted media server. With ICE, the resources used by the media relay nodes are reduced by 90%. When you enable ICE, all Webex calls with MPP phones negotiate the most optimized path with this feature.

To configure this feature you modify the database at a tenant or device level. Only Cisco Service Readiness Engineering (SRE) team can modify this feature. MPP supports full ICE mode as per RFC-5245.

To enable ICE on MPP, the variable ICE_STUN_Enable in the device profile is modified with the following syntax.

<STUN_Enable ua="na">Yes</STUN_Enable>
<ICE_STUN_Enable ua="na">Yes</ICE_STUN_Enable> 
<STUN_Server ua="na">10.89.68.76</STUN_Server>

The configuration variable ICE_STUN_Enable is hidden on the phone web interface. The others are shown on the phone web interface.

This feature cannot be configured or modified from the phone web interface. The end user can't modify this feature.

LDAP Cache for SIP User Credentials

The phone now saves the LDAP user credentials in a local cache when the credentials are configured manually on the phone, administration web page, or phone configuration XML file (cfg.xml). In addition to the host user of the phone, the LDAP cache mechanism is also applicable for the users who sign into the phone with the Flexible Seating or Extension Mobility feature.

The cached LDAP user credentials are associated with the SIP user ID. When a user accesses the LDAP directory, the phone checks the LDAP cache to locate the user's credentials. If the credentials are found in the cache, the user can access the LDAP directory without the need to sign in.

The phone can save up to 50 user credentials. The phone removes the least-used credentials when the cache size limit is reached.

LDAP StartTLS Support

The phone now supports Start Transport Layer Security (StartTLS) for the communications between the phone and the LDAP server. StartTLS begins as a plain text connection over the standard LDAP port. It provides the flexibility for encrypted or unencrypted communications according to the actual situation of the LDAP server. If the server supports to upgrade the connection to TLS, then StartTLS encrypts the communications using TLS. Otherwise, the communications are unencrypted, for example, in plaintext.

To enable this feature, use the StartTLS Enable field under the LDAP section in Voice > Phone of the phone administration web page.

Menu Visibility Configuration

You can configure the phone to:

  • show or hide specific menu items on the phone screen.

  • enable or disable the personal directory.

  • enable or disable the ability to search for contacts in all the directories.

By default, all the menu items, the personal directory, and the feature of contact search in all directories are available to users. You can hide particular items with the fields in the Menu Visibility and Directory Services sections on the Voice > Phone tab in the phone web interface.

If you hide a menu item, it doesn't display on the phone screen. If you disable the personal directory, users can't see Personal address book on the phone screen or the Personal Directory tab in the phone web interface. In this case, users can't add contacts from the call history. If you disable the contact search in all directories, users can only search for contacts in a selected directory, instead of all the directories.

Reverse Name Lookup for Inbound Calls using Broadsoft Directories

The reverse name lookup searches the phone's external directories. When a search succeeds, the name is placed in the call session and in the call history. For simultaneous multiple phone calls, reverse name lookup searches for a name to match the first call number. When the second call connects or is placed on hold, reverse name lookup searches for a name to match the second call. The reverse lookup searches the external directories for 8 secs, if in 8secs there is no result found, there will be no display of the name. If a result is found in 8secs, the name is diplayed on the phone. The external directory search priority order is : BroadSoft(XSI) > LDAP > XML.

Reverse Name Lookup for Local Directory

This feature enables to do a reverse name lookup against local contacts for BroadWorks server call logs. If the call number of server call logs matches that in the local directory, the call name of server call logs will be replaced with contact name in the local directory. Also, if the call number does not match any entry in local directory, the call number will do caller id mapping and lookup the local directory again.

SIP Proxy Redundancy Enhancement

The SIP Proxy Redundancy enhancements are:

  • Increase support for up to six NAPTR records and six SRV records in a DNS query

  • Add ability to seamless switch between different SIP transport protocols during server failover and failback

  • Add ability to disable SIP proxy failback. Set the Proxy Fallback Intvl parameter to 0 in the phone web interface or the configuration file.

  • Retain an active call on the fallback server until after the call completes. After the call completes, if the primary server is available and the failback conditions are met, then perform the failback.

Limitations and Restrictions

Phone Behavior During Times of Network Congestion

Anything that degrades network performance can affect phone audio and, in some cases, can cause a call to drop. Sources of network degradation can include, but are not limited to, the following activities:

  • Administrative tasks, such as an internal port scan or security scan

  • Attacks that occur on your network, such as a Denial of Service attack

Multicast Paging Scripts Change to Empty after the Upgrade (CSCvu23613)

The default values of multicast paging scripts change from 800 to empty automatically after the upgrade to 11.3.2.

This behaviour typically occurs if the multicast paging scripts were not modified before the upgrade.

This behaviour doesn't occur if you have previously changed the multicast paging scripts to non-default values before the upgrade.

On the phone administration web page, you can check the values of multicast paging scripts from Voice > Phone > Multiple Paging Group Parameters.

After the upgrade, if you want to use the default values in the previous releases, you can configure the parameters on the administration web page.

The following list shows the default values of the multicast paging scripts in the previous releases:

  • Before 11.3(1) firmware releases, the default values are:

    pggrp=224.168.168.168:34560;name=All;num=800;listen=yes;

  • In 11.3(1) firmware release, the default values are:

    pggrp=224.168.168.168:34560;name=Group_1;num=800;listen=yes;pri=1;codec=g722

You can also configure the parameter in the phone configuration file with XML(cfg.xml) by entering a string in this format:

  • <Group_1_Paging_Script ua="na">pggrp=224.168.168.168:34560;name=All;num=800;listen=yes;</Group_1_Paging_Script>

  • <Group_1_Paging_Script ua="na">pggrp=224.168.168.168:34560;name=GroupA;num=800;listen=yes;pri=1;codec=g711a;</Group_1_Paging_Script>
