 Operator Extension: Choose an extension to be operator extension. When an incoming call has been directed
to voicemail, then by pressing ‘0’ the caller will be put through to the operator extension.
 Global Ring Time: If it’s not specifically configured, an incoming call will ring the extension for the time given
here.
 Outbound Call Transfer: Allow outbound phone calls to be transferred, if enabled it might cause phone call
problem in certain situations. For example, an outbound phone call had been placed to another IVR system,
the keypress might be recognized as transfer request on your own IPPBX system.
 Music On Ringback: If enabled, callers will hear music instead of ringback tone when calling extensions.
 Auto Answer: Auto-answer enables the IPPBX to automatically answer the inbound calls from analog ports.
 PPI: The P-Preferred-Identity (PPI) header is used among trusted SIP entities (typically intermediaries) to
carry the identity of the user sending a SIP message as it was verified by authentication.
 Analog Fast Sent Number: This parameter will always add a # at the end of the numbers dialed through the
PSTN lines, it will cause the carrier to forward the calls immediately instead of waiting till digits timeout. If
your PSTN line carrier supports this feature, you may enable it for faster outbound phone calls via PSTN.
