again, or when logging in for the first time. Previously, the Web interface presented a login popup
prompt.
New capability for phones to operate with 18 Multiple Points of Presence (MPOPs) including
Microsoft Skype for Business clients. (The 420HD non-GbE phone supports up to 5 MPOPs).
Block User Sign-Out. Administrators can disable users from signing out. A new configuration file
parameter 'lync/userSetting/prevent_user_sign_out' has been added. Default=0 (disabled). When
enabled, the Sign out softkey is not displayed in the LCD. Identical to the previous version's
configuration file parameter 'voip/common_area/enhanced_mode', which was specific for Common
Area users, the new configuration parameter applies to all users. The new parameter takes
precedence over 'voip/common_area/enhanced_mode'.
IT administrators can disable user phone microphones using a new configuration file parameter
'voip/audio/microphone/enable' which by default is enabled.
3.1.2 Known Constraints in Version 2.0.13
Version 2.0.13 includes the following known constraints:
Boss Admin:
• When the Boss configures an Admin user, the Admin's username is shown instead of the
Admin displayed name.
• When the Boss performs a handoff to Admin, Admin cannot transfer the call back to the Boss
with a single step ‘Handoff’ softkey. Call Transfer is possible using the Transfer options.
• The list in the Dialed Calls screen, shown after pressing the REDIAL key, is incorrect after a
call to Boss is made and the call is answered by Admin. When the caller presses REDIAL,
they see Admin's phone number instead of Boss'.
• Admin who is in two ongoing calls or local conference call, cannot pick up another call Boss
holds.
• The incorrect pickup screen may appear when Admin has more than one Boss (mixup
between Bosses).
• Response Group - A call initiated by Admin on Boss' behalf to Response Group cannot be
picked up by Boss.
• Response Group - Incoming call from Admin (on behalf of Boss) appears in Response Group
agent's phone LCD as a regular call and not as a Response Group call.
• When Admin receives a second call (for Boss), the BossVM softkey is not functioning.
• Call pickup after Handoff of the same call and Handoff after call pickup of the same call are
currently not possible and target to be supported in next release.
BToE:
• BToE does not function if PC users are switched without logging off first.
• Call Park can be performed from the phone, not from the Skype for Business client.
• Audio Primary Device:
Switching Audio Primary Device during a call from the Skype for Business PC client to the
phone does not function. This is a limitation of Skype for Business-compatible IP phones.
(Audio Primary Device can be switched from the phone to the PC client.)
During an incoming Skype for Business call, the Primary Device cannot be changed in
the Skype for Business Conversation window. It can be changed when making outgoing
calls, and for incoming PSTN calls.
• Video Calls:
Outgoing and incoming video calls are possible using the Lync PC client with the following
limitations:
When a paired user has an active video call (e.g., answered from the Skype for Business
PC Client), attempting to answer another call (either from the Lync PC client or with the
phone) disconnects the video call.
