2.0
Download - REPLACED BY 2.1 ABOVE
Changelog
- SmartStream
- Advanced Audio Routing
- New Audio Routing drop-down in call dialog and quick-dial configuration to specify Stereo, Left Only or Right Only
- New Incoming Call Audio Routing drop-down in System Settings to specify Stereo, Left Only, Right Only or Alternating
- Use a mono codec where relevant (Opus) when a mono routing is specified
- Multiple Simultaneous Calls (licensed feature)
- Allow up to 8 simultaneous calls, each with individual audio routing
- Status tab displays a table of all active calls with individual routing indication (L / R speaker icons), metering and drop button
- New Drop All button hangs up all active calls
- Expanded RTP port range (any port forwarding on firewalls / routers must be updated): 15004-15515
- USB keyboard support - allows dialling using a keyboard or number pad:
- Type a username (when registered to a SIP server) or full SIP URI and press enter to dial
- Backspace key can be used to delete previous characters
- By default, audio routing will be stereo; to override, when making the call, press and hold enter, press / on the number pad for left-only or * on the number pad for right-only, then release enter
- Escape and number pad . keys behave in the same way as front-panel DROP button on CallMe-TR: press and hold for 1s to drop all calls; press and hold for >=20s to factory reset (particularly useful on CallMe-TS)
- New "individual drop" mode for front-panel DROP button to drop a single call when several are active: a brief press of DROP activates the mode for 5s, after which a CALL button, or DROP + a CALL button (exactly as for dialling), can be pressed to drop the corresponding quick dial
- Full ICE support: new NAT Traversal drop-down on SIP Settings tab offers None, STUN or ICE
- New Register Keep-alive option on SIP Settings tab to maintain NAT binding for SIP port (improves compatibility with some SIP servers where incoming calls would intermittently fail)
- Improved front-panel LED behaviour. LEDs now illuminate correctly when quick-dial specified by username, without sip: prefix etc..
- Display caller name for incoming calls where available (in addition to SIP URI)
- New Friendly Name field in call dialog and quick-dial configuration to specify a name for the connection which will be displayed on the Status tab for outgoing calls
- Show CONNECTING status on web interface to indicate when a call attempt is in progress
- New Force Codec Choice option on System Settings tab to offer only the selected codec for a call (rather than just making it the preferred choice)
- Detect connection loss between web interface and codec; disable web interface when this occurs and automatically reconnect
- Improved call auto-reconnect behaviour: only reconnect automatically if the call actually connected successfully, and only if it wasn't actively dropped by either end. Continue to retry even on local network failure.
- New Licences panel on System Settings tab displays licensed features and allows add / remove of licences
- New MAC address display on System Settings screen
- Support for RØDECaster Pro USB audio
- Reduced jitter with USB audio devices
- Improved robustness of settings to power failures
- Fix to prevent IPv6-based spam calls and fix outgoing call failures after reboot when routable IPv6 address assigned by DHCP
- Fix to prevent the indication of "phantom" calls after automatically trying to reconnect after local network failure
- Fix for faster re-registrations to non-conformant SIP servers
- Internal performance improvements and memory leak fix
- Experimental wifi hotspot mode:
- When a compatible USB wifi adapter is connected, CallMe-T will create an open hotspot with the same name as the Device Name
- Connect to this network from a phone, tablet or PC (choose to "Stay connected" when prompted by Android despite no internet)
- Browse to http://10.0.0.1 or http://c.mt to access the normal web interface
- The interface currently doesn't work well on small screens, but should be good enough to configure IP settings and quick dials
- May not work on all browsers / devices; for best results, use Chrome
- New LED modes to reflect multiple calls:
- CALL buttons
- When the main or shift QD assigned to a button is connecting: flash 200ms on, 200ms off; otherwise:
- When only the main QD assigned to a button is connected: on solid
- When only the shift QD assigned to a button is connected: flash 500ms on, 500ms off
- When both main and shift QDs assigned to a button are connected: flash 2000ms on, 500ms off
- DROP button
- When "individual drop" mode is active: flash 100ms on, 100ms off; otherwise:
- When at least one call is connected: flash 500ms on, 500ms off; otherwise:
- If the unit is registered to a SIP server: on; otherwise: off
