The table below shows the constraints that were known to exist in previous releases but which are now resolved in Version 3.0.1.

Incident Description

IPPSFB-10191 CDP is missing the "DEVICE ID" header.

IPPUC-6137 One-way voice audio occurs in OVR Limited Service.

IPPSFB-9991

[BToE] A failure occurs with the Consultation Transfer functionality when using BToE and the FonComfort application.

2.3 Known Constraints in Version 3.0.1.426

The table below shows the constraints known to exist in Version 3.0.1.426.

Table 2-2: Known Constraints in Version 3.0.1.426

Incident Description

- 420HD IP phone does not support:

 Exchange integration (Calendar)  Visual Voice Mail  Outlook contacts and Skype for Business 'Favorites' contacts

106815

106161

[Boss-Admin] Second pickup sometimes fails, i.e., if Admin picks up a Boss call and then Boss tries to pick up the call back).

[Boss-Admin] Skype user whose name starts with a small letter and configured as Admin, it’s displayed on the Boss phone as a URI address rather than with the display name.

105852

106432

Version 3.0.1 15 400HD Series IP Phones for Skype for Business

[BToE] In the scenarios listed below, the phone performs as a PC playback de standalone phone. Some call management capabilities consequently go missing, e.g., hold, transfer, conference roster screen. In these scenarios, a regular call may start similarly to a video call, i.e., the phone is used as the PC playback device. Example scenarios:

 RGS/Delegate call made on behalf from the PC client  Call from IM (Instance Message) that was opened before the phone was paired.

This is aligned with Microsoft's BToE implementation.

[BToE with Delegation] When a video call comes in to the Boss, a paired Admin phone will not ring but can accept the call. This is aligned with Microsoft's BToE implementation of video calls.

[Skype for Business 'Favorites'] Only the SIP URL is added to 'Favorites' when adding a cont from the Personal Directory or from Outlook.

[Skype for Business 'Favorites'] The phone does not retrieve Outlook contacts from On Premises Exchange servers.

[Multi-Party Skype for Business Remote Conferencing] When a Conference is locked, the phone cannot add a user (Skype for Business client or other certified phone) if not admitted within 15 seconds.

Sometimes, the user is unable to join a Skype for Business meeting whose configured 'End time' has passed.

[BToE on their PCs must uninstall it before installing the new version of the application.

[BTOE] When a paired user answers an incoming team-call, the phone does not present the call as a team-call.

[BTOE] When a paired user answers a delegated call, the phone does not show that this is a delegated call.

[BToE video] A paired user cannot answer a second incoming call via the Skype for Business client when having an active video call.

[BToE - video] On a PC with low CPU resources, interference in the voice of a video call might be experienced.

-

[BToE] Call Transfer from the Skype for Business client to another user can be performed from the phone but not from the client.

[Boss Admin] When the Boss configures an Admin user, the phone's LCD displays the Admin's username instead of the Admin's regular name.

[Boss Admin] When Boss performs a handoff to Admin, Admin cannot transfer the call back to Boss with a single-step Handoff softkey. Call Transfer is possible using the Transfer options.

[Boss Admin] 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'.

[Boss Admin] Response Group - A call initiated by Admin on Boss' behalf to Response Group cannot be picked up by Boss.

[Boss Admin] 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.

[Boss-Admin in a conference scenario] The Rosters screen does not indicate if a participant is 'On-behalf '.

Provisioning by the Redirect Server doesn't function if the phone receives any provisioning of configuration URL via DHCP options.

Call Log information is saved to the phone file system once every 6 hours. Consequently, Call Log information such as missed, received and outgoing calls may not be saved after restarting.

Accessing the phone's Web interface with HTTPS via Internet Explorer requires TLS 1.2 support. TLS 1.2 can be set in Internet Explorer via Tools > Internet Options > Security tab. If TLS 1.2 cannot be supported, the Chrome browser can be used instead of Internet Explorer.

The Chrome browser cannot be used to manually update the phone's firmware through the Web interface over HTTPS protocol. Internet Explorer can be used instead.

[Voice Mail] If the user calls their Voice Mail and then gets an incoming call, the call with the Voice Mail is ended rather than put on hold.
