Version 2.0.13B 22 Document #: LTRT-08271
and then disappears.
DHCP Option 160 doesn't read correctly when there's no "/" (forward slash) at end of sent path.
MPOP (Multiple Points of Presence): In a Lync environment, each user can have only up to five
devices connected simultaneously (for example, PC client, mobile application, and up to three IP
phones). Adding users using the Lync Team Call may also introduce this limitation. This issue is
planned to be resolved in the next release.
Presence of Federate users is not displayed in Call Log, though BLF presence works well.
A phone which is in two active calls cannot be joined to a remote conference by one of the two
callers' devices.
The phone cannot perform Semi-Attendant transfer via Call Log or Corporate Directory.
RTCP-XR is not supported in this version and is planned to be supported as part of the QoE
Reporting feature in the next release.
If a call was made from the phone's Contact Search and the phone number contains parenthesis
"()", the dialed number is not displayed on the phone's LCD.
On rare occasions, the phone enters “sign out” state and does not recover automatically, but
requires the user to sign in manually by pressing the Sign in softkey.
If the Active Directory search fails and PAID is included in the SIP INVITE message, the phone
does not display the callee / caller name.
Lync mobile client: The call may disconnect when an external Lync user calls from the phone to a
Local (internal) Lync user who answers the call with the Lync mobile client.
USB headset limitations:
• Voice may sound metallic or sometimes noises may be heard during a call. Switching the
phone's audio device to Handset/Speaker and then returning to Headset resolves this issue.
• When making a local conference call (and the phone is not in BToE pairing mode), the
phone's user interface reacts slowly.
3.2.3 Resolved Constraints in Version 2.0.11B
The following constraints from the previous release have now been resolved in Version 2.0.11B:
Calls between two phones that are signed in with the same user cannot be made.
Translation fixes in Hungarian language.
In some Lync environments, a noise may be heard on the phone when calling a user that is
configured with 'Simultaneously Ring'.
In some environments, the phone may send a request for a new IP address once every three
DHCP lease time cycles. A fix for this issue already exists (as part of the next release) and can be
provided on request.
Ringback may stop after only one ring when calling a user that is configured with 'Simultaneously
Ring'.
One-way voice occurs when the call is placed on-hold for more than 30 minutes and then resumed.
BToE: No voice is experienced when a paired user joins a Lync Conference Meeting as an external
user.
The phone sometimes does not attempt to re-register when it recovers from a lengthy network
disconnection.
BLF blinks when the phone is in "Busy" state.
Boss Admin: Boss fails to remove Admin delegation when Boss and Admin phones belong to
different Lync pools.
LLDP process crashes on rare occasions.
Phone crashes when calling using a speed dial that was configured with a long name.
Phone may crash on rare occasions in call transfer scenarios.
Phone may crash on rare occasions in Remote Conference Call scenarios.
