Resolved Issues
| Category | Issue ID | Product | Description |
| Audio | VOICE- 74909 | Edge E Series | Received audio played from the handsfree speaker may be distorted when noise sources are present at the microphone for call start while the AEC is converging. |
| Call Management | VOICE- 74962 | CCX Series Edge E Series Trio | Phones that have failed over to a backup SIP server for extended durations may cease to send REGISTER messages and eventually go offline. |
| Call Management | VOICE- 74858 | Edge E Series | Changes to a call’s state, including remote calls monitored on an SCA line, can cause the phone to freeze if they occur while searching the contact directory. |
| Call Management | VOICE- 74857 | Edge E Series | When the Line Key Reassignment feature is enabled, not all speed dials marked as favorites appear on screen, and some favorites aren’t explicitly assigned to a line key. |
| Calling | VOICE- 74438 | CCX Series Edge E Series | An incorrect change of a default configuration value causes Edge E and CCX phones that use Broadsoft Flexible Seating guest logins to show the wrong caller ID in calls. |
| Certificate management | VOICE- 75070 | CCX Series Edge E Series Trio | The SCEP sourced CA certificate isn’t included in the list of trusted CM when a TLS profile’s CA list is set to “All.” |
| Conference Management | VOICE- 74787 | Trio C60 | For locally mixed conference calls on the Trio C60, the participant control panel will close and be unrecoverable for the rest of the call if all participants individually place the call on hold. |

| Shared Lines | VOICE- 75053 | Edge E Series | The shared line LED state may be incorrect due to a race condition where the SIP CANCEL of a remotely answered call arrives after the shared line’s SIP NOTIFY with state information. |
| Software Updates | ECS- 1520 | Trio C60 | Trio C60 occasionally rejected a software upgrade due to memory constraints but now optimizes memory to reduce the amount of space needed for an upgrade before starting the upgrade. A factory reset may be required to upgrade to software with this resolution available. |
| User Interface | VOICE- 74308 | Edge E Series | The keypad diagnostics tool on Edge E incorrectly quits the diagnostic test after a single press of the unlit page button of an expansion module instead of after the second press |

| Category | Issue ID | Product | Description | Workaround |
| Application | VOICE- 74788 | CCX 500 CCX 505 | Choosing the Dialpad Base Profile allows DiaIpad’s service to change the admin password before a user signs in.
