PTT Express 3.1.20

1.       Major Features

    a.    After changing the talk-group or changing the status, the PTT Express user interface would be on the fore-ground to facilitate confirmation of the changed talk group and to allow user to continue making PTT calls when CallKeyConfig is 0 (on-screen buttons).

    b.    Recovery update procedure : Copy the Recovery update package for PTT Express installation/uninstallation for KK to the internal storage of respective device and perform the recovery update as per the procedures mentioned in the OS recovery update guidelines

    c.    To change the settings of the PTT Express client, modify the ptt_settings.xml file located at /enterprise/device/settings/ptt.

    d.    To enable Debug Logs, follow below steps:

        1.    Pull ptt_settings.xml from /enterprise/device/settings/ptt/ folder.

        2.    Edit< setting name="logLevel">Debug

        3.    Check for /storage/sdcard0/PTT folder.

        4.    Logs will be created with DEVICE_MODEL_MAC_ADDRES_PTT_log.txt

    e.    The previous log file is saved as DEVICE_MODEL_MAC_ADDRES_PTT_log.txt.bck.

    f.     The default log level is set to ‘None’ (to avoid issue 74744). Update value of ‘log_level’ in ptt_settings.xml to enable the logging.

    g.    Log file should not be renamed or deleted while logging is active. Copy the log file to PC or other folder if snapshot log file has to be created.

    h.    Use ‘adb’ to copy the logs to PC.

    i.      CDR log file will be created, if not exist, only when enableCDR is true and the first call happens on channel whose CDR is true or Private call.

    j.      PTT HEADSET Usage Notes:

    k.    Group call is initiated by pressing (and holding) headset button. Due to special PC implementation, there will be 600ms delay after user presses the headset button. User shall start speaking only after talk permit tone is played.

    l.      Private call is initiated by pressing headset button in following sequence: Down, Up and Down (and hold). These 3 clicks shall occur within 600ms. If there are more than 3 clicks within 600ms, then the clicks will be discarded and nothing will happen.

    m.   Enabling display of call statistics - The PTT Express client provides a toggling option on the settings page to enable/disable the display of toast messages showing call statistics.

    n.    Mute functionality - The PTT express client allows itself to be muted and un-muted using the mute button on the main dialog, or using the key configured in the ptt_settings.xml or using intents. When the client is muted, it is indicated on the UI and on the status bar. While in Mute state, the client’s audio and tones are muted and PTT key events ignored. The Mute functionality is not persistent across the reboots or application restarts. However the Mute functionality is persistent across Enable and Disable of the service.

    o.    Audio feedback Functionality – The PTT Express client allows voice feedback on Channel and Profile Switch. The configuration “audioFeedback” should be set as Default to enable the Audio feedback. Based on the language value set in the profiles, the audio would be played, in that specific language. The value of the language is set as locale string defined in Only installed languages are supported and the language list would be listed in accessibility settings on the device.

    p.    PTT supports Airwatch and SOTI MDM for deploying configuration changes.

    q.    Full-duplex client co-existence - The PTT Express client supports a configurable option “fullDuplexClientCoexistance” to coexist with full duplex WAN or VOIP client. There is another configurable option “vibrateOnVoiceCall” which allows full duplex incoming calls to vibrate when PTT is in call. The following is applicable when “fullDuplexClientCoexistance” is set to true:

    r.     When there is an outbound call made or when an inbound call is accepted on the full duplex client, PTT Express enters into co-existence mode by muting itself and showing yellow icon on the status bar. It also stops playing out any tones or calls and ignores key requests for PTT calls.

    s.    When a full duplex call terminates, PTT Express exits the co-existence mode to resume normal operations.

    t.      Few full duplex clients allows PTT Express to exit coexistence mode when its call is put on hold and then enter back to coexistence mode when the call moves out of hold state.


2.       SPR fixes

    SPR 28025 Disabling PTT express via SOTI.

3.       Known issues

    a.       The coexistence solution is dependent on the announcement of states done by the full duplex client. Few variations mentioned beneath have been observed in which case PTT Express client may not be able to enter or exit from coexistence mode.

    b.      While coexisting with few versions of VOIP clients and the WAN client, PTT Express cannot come out of coexistence state when a call is put on hold.

    c.       Specific version of Jabber client is not seen to announce MODE_RINGTONE due to which PTT Express cannot honor “vibrateOnVoiceCall” settings.

    d.      Certain full-duplex clients are at times seen to fail in announcing their call states which can result in PTT Express not entering/exiting coexistence mode as expected. It can be recovered when a succeeding inbound/outbound established call is terminated. In some cases, a warmboot might be required

    e.      After Reset (or) reboot key presses will not be detected for initial 30 secs.

7.    DWDemo now shows the scanner firmware version if the scanners supports the feature.
