Enable exit code 0 from voicemail (available starting from Beta 3.88.41711.32)

Starting from WMS Beta Version 3.88.41711.32, support for exit code 0 from voicemail allowing caller to speak with an operator was added

How to use:

  • Add the letter  ‘o’ as called number to the Dialplan context (that is where the “0” key sends the caller)

How to disable:

  • Add the parameter operator=no to the file voicemail.conf. It allows sender to hit 0 before/after/during leaving a voicemail to reach an operator

Disable devices sync

Important: By default, the sync is enabled. It is necessary to disable it in case of FAILOVER scenario on Failover PBXs!

To disable the sync:

  • Add parameters disable_sync_portal=1 “ and disable_sync_manual=1 to the config file /rw2/etc/pbx/device_sync.conf
    Available values: 1 – sync is disabled; 0 – sync is enabled

Enable Q-value (serial forking) for trunk registration

To enable q-value (serial forking) parameter via custom register string:

  • Copy registration line for some trunk from /etc/callweaver/sip-registration.conf (Example: register => 144?144:123456:”144″@10.168.0.144:5060)

  • Uncheck Enable registration option in Trunk Settings (WMS -> Trunks)
  • Add new line into /etc/callweaver/sip-general-custom.conf: register => 144?144:123456:”144″@10.168.0.144:5060~~0.6 (where 0.6 is q-value)

  • Run the command:

    callweaver -rx “sip reload”

Enable g729 transcoding for web phone calls to trunks which do not support G711

Important:

  • It’s not recommended to enable this feature, as it reduces call quality and generates useless load on CPU!
  • It must be enabled only if the operator doesn’t support g711a/u for some calls
  • It can generate CPU overload and problems if too many calls use it; in this case it is recommended to use another operator which supports all the needed codecs ( g711a / g711u / g729)


Note: Feature is supported only on PBXs with modern CPU or Cloud.


To enable g729 transcoding, edit the file /etc/callweaver/sip-general-custom.conf:

  • Add the parameter g729_transcoding=yes to [general] section



  • No labels
