Billing
When a mobile originated call is initiated from the RJ11 port (PSTN/
PABX) and the call is connected to the remote user, the system
sends the billing tone to the PSTN/PABX at the RJ11 port. The tone
lasts for 500ms. Some PABX can catch this tone and start billing the
user at the PABX for the call.
Refer to “Handset Advanced Operation” for setup instructions.
