Analog Settings
Global Analog Settings are used for configuring the IPPBX system to seamlessly work with the telephone lines from
your telecommunications providers.
 Caller ID Signaling: The signaling type applied on the PSTN lines to pass caller ID.
 Bell-US—Also known as Bellcore FSK. Used in the Canada, China, Hong Kong and US.
 DTMF—Dual Tone Multi-Frequency. Used in Denmark, Finland and Sweden.
 V23—Mostly used in UK.
 V23-Japan—Mostly used in Japan.
 Caller ID Start: Defines when the caller ID starts.
 Ring—Caller ID starts when a ring is received.
 Polarity—Caller ID starts when polarity reversal starts.
 Polarity(India)—Can be used in India.
 Before Ring—Caller ID starts before a ring received.
 CID Buffer Length: The buffer length can be used to store caller ID info.
 Ring Debounce: Sets the minimum time in milliseconds to debounce extraneous ring events.
 DTMF Hits Begin: Sampling matching value of DTMF caller ID digits, you can choose 1 to 5 digits been
matched then to consider it as part of the Caller ID.
 DTMF Misses End: Sample matching value of DTMF caller ID digits, you can choose 1 to 5 digits been
mismatched then to consider it’s not part of the caller ID.
 Detect Caller ID After: Sets the IPPBX to detect Caller ID after how many rings been detected.
 Opermode: Set the Opermode for FXO Ports.
 ToneZone: Select the tone zone of your country.
 Send Caller ID After: Certain countries (UK) have ring tones with different ring tones (ring-ring),which means
the caller ID needs to be set later on, and not just after the first ring, as per the default (1).
 Denoise: The denoise parameter will help on noise reduction of the noisy analog lines, especially when gains
have been increased on the lines.
