Change Log

New Features


    • IPAC from V2.10 is the official and only supported firmware for Annuncicom MPI400. Developments on this release are mostly focused on adding features supported mainly on this product

  • Digital Input Operation modes: Configurable individually for each dry contact input available

    • SIP: initiate calls, accept incoming calls, hangup calls when the input is closed.

    • SIP “Press-Hold-Release”: same as SIP with the difference that any state change of the input triggers the action to perform.

    • SIP Refer Blind Transfer: Transfer a call to the configured extension

    • Input operational modes and configuration of the extension to be dialed are assigned in the new IO Page on the web interface (only available on hardware with input and output capabilities)

  • Relay Output activation: Configurable individually for each dry contact input available

    • Relay activation on SIP RINGING state (de-activation when ringing is over)

    • Relay activation on SIP ACTIVE call state (de-activation when call is hangup)

    • Relay activation on SIP DTMF sequence (de-activation upon reception of DTMF de-activation sequence, configured separately)

    • Relay activation from REST API call (if enabled in the configuration)

    • Relay activation modes are configurable in the Relay section of the IO page (only available on hardware with input and output capabilities)

  • Audio Input management:

    • Added support for gain adjustment of an audio input interface in the settings page of the web interface:

      • Line In: to get the signal from the line level input

      • Mic: to get the signal from the standard mic input

      • Phantom Mic: to get the signal from the phantom powered mic input

      • Gain: to adjust the gain of the selected input

  • SIP Source

    • Added SIP ringing tone to be played when auto answer is off

    • Added SIP “Half Duplex” mode with “level” and “timeout” adjustments to enable fine tuning of “talk” and “listen” status

    • Added “Capture Buffer Latency” to adjust the input buffer of the SIP Client

    • Added “Audio Input Level” to fine tune the input level setting of the SIP client

    • Added “Auto-Answer” enable / disable option and “Auto-Answer timeout” to pick up calls automatically after the specified interval

  • REST API Extension:

    • Extended REST API with new calls to:

      • GET Input Status

      • GET Relay Status

      • SET (PUT) Relay Status (API control must be enabled on the intended relay)

Fixes / Improvements

Known Limitations / Issues

  • Configuration Tool: SIP Server settings related to username must be entered manually in the tool for each device despite they are copied from one device to all others when pushing the configuration or copying and inserting.

  • Configuration Tool: the green cell indicating the playing source is not updated in real time. It requires the user to click the READ ALL button. 

  • RTP Regular mode: frequency drifts (playback speed adjustments) when playing formats with lower sample rates (e.g. G711 @ 8kHz)
