Issue	Fix
Calls to Office Communicator 2007 Phone Edition from endpoints that use ICE v19 clients fail.	The Session Description Protocol (SDP) attributes now support Invites from ICE v19 clients.
The Real-time Audio (RT Audio) Narrow Band (NB) codec causes audio distortion.	This codec was fixed, and there is no longer an audio distortion.
The mouth-to-ear latency is higher than expected because of the route and priority route of the data.	The route and priority route of the data were adjusted and the mouth-to-ear latency was reduced.
RT Audio on the phone exhibits popping sounds and clicking sounds when hardware volume is near maximum and packets are arriving from the AMD64 build of RTAudio codec.	Users no longer experience popping sounds and clicking sounds.
The RT Audio healer overreacts to small jitter fluctuations and does not optimize delay for low jitter.	The RT Audio healer no longer overreacts to small jitter fluctuations.
Unnecessary items are logged in the log files.	There is reduced logging volume because unnecessary logs are removed.
Audio distortion occurs when the encoder has some slips where some frames have a zero gain.	The encoder no longer causes audio distortion.
The RT Audio healer sometimes causes latency spikes.	The optimized RT Audio healer delivers more consistent latency.
There is memory leak with every screen touch.	Screen touches no longer cause memory leak.
The error message for incorrect credentials shows / instead of \ for the domain field: "Cannot sign in. Please verify your sign-in address, domain/username, and password and try again"	The error message was changed.
You cannot search Outlook contacts soon after you sign in to Office Communicator 2007 Phone Edition.	The error condition that leads to this issue was fixed.
When a close is issued after shutting down the audio, the stream context is asked to close and free itself. However, the specific check is not always accurate. In most cases the object is not deleted. This behavior causes memory leak.	The check was expanded to examine another variable that is set based on the Start function calls and the Stop function calls to the object.
A call is not established when the ICE v19 endpoint retries by sending ICE v6 Invite.	The transaction state is cleared so that the retry is not rejected as a duplicate message.
The user hears artifacts in audio (audio distortion) during the call because of an internal memory codec issue.	The codec was fixed, and there is no longer an audio distortion.
The user hears a jitter in certain situations.	The RT Audio healer has removed the jitter.
Reduction in the Dynamic Voltage Frequency Scaling (DVFS) during a call causes problems.	DVFS stays at high speed until the media stack stops.
The fingerprint performance is reduced and remains reduced after a call is placed.	The fingerprint performance has improved by increasing the priority.
Audio is played to the speakerphone based on the ringer volume setting instead of based on the speaker volume setting.	This issue was corrected.
By default, the volume for the ringer, handset, and speaker is set to maximum.	By default, the volume for the ringer, handset, and speaker is now set to half volume.
A call that is in a connecting state is disconnected before the remote party ends the call.	The call connecting time-out was lengthened.
If both sides of the phone call are silent for about 30 seconds, the call is disconnected.	Call are no longer be ended automatically.
The error message is not descriptive when user dials a number that does not map to a dial plan.	The error message was made explicit to indicate that the format of the number that the user has dialed does not match configured dialing rules.
Endpoints that require the support of the SIP replaces method reject calls from Office Communicator 2007 Phone Edition.	Office Communicator 2007 Phone Edition now advertises support of the SIP replaces method.
