   Advanced Options
   Framing and coding options	Specify the type of framing and coding to provision the PRI with your PSTN service provider.
   Clocking options	Select the clock synchronization option for the FortiVoice phone system: Clock sourcing from PSTN network Internal clocking source This option setting does not need to match the one used by your PSTN service provider.
   Receive sensitivity	Select the level of receiver sensitivity. This option allows the phone receiver to pick up the required level of phone signals and operate more efficiently. This option setting does not need to match the one used by your PSTN service provider.
   D-channel signaling format	Select a signaling method for the D channel. This format carries the information needed to connect or disconnect calls and negotiate special calling parameters such as automatic number ID, call waiting, and data protocol. The D channel can also carry packet-switched data using the X.25 protocol.
   Line build out	Select the line build out (LBO). Use LBO settings to adjust the output power of the transmission signal to achieve equal level point (ELP) at the DSX.
   D-channel	Depending on your selection in Type, the default channel numbers are: Full T1: 24 Full E1: 16 Make sure to configure this setting to match the one used by your PSTN service provider.
   B-channel	Depending on your selection in Type, the default channel numbers are: Full T1: 1-23 Full E1: 1-15, 17-31 You can also configure individual channels alongside channel ranges.

   Dialplan type (TON)	Select a number format for placing a call from FortiVoice to the service provider. The values for this option are provided by the service provider. This option appears only if you select PRI signalling, CPE side or PRI signalling, network side for Editing a trunk profile for a PRI gateway.
   Local dialplan type (TON)	Select a number format for placing a call from the service provider to FortiVoice. The values for this option are provided by the service provider. This option appears only if you select PRI signalling, CPE side or PRI signalling, network side for Editing a trunk profile for a PRI gateway.
   Connected party notification dialplan Type (TON)	Select a number format used in caller-ID and remote party ID (if supported by the service provider). The values for this option are provided by the service provider. This option appears only if you select PRI signalling, CPE side or PRI signalling, network side for Editing a trunk profile for a PRI gateway.
   PRI indication	Select a value that is typically provided by the service provider. However, some providers allow this value to be set on the PBX. In Band: Call failure tones, for example, busy signal and out of service messages, are played back as audio from the service provider. Out of Band: Call failure tones are generated by FortiVoice with the service provider sending a code instead of a tone. This is required for some automated dialing scenarios, but you will often lose extra information that may be included in the recorded message. This option appears only if you select PRI signalling, CPE side or PRI signalling, network side for Editing a trunk profile for a PRI gateway.
   PRI R2 Setting	If you select PRI R2 signaling in the Signaling field, then this option is active. The PRI gateway supports many localized implementations of R2 signaling because there is no R2 signaling standard.
   Country	Select the country for PRI R2 signaling settings.
   Max ANI digits	Telephone companies use the automatic number identification (ANI) to identify the directory number (DN) of a calling subscriber. This number allows subscribers to capture or display a caller's telephone number. Enter the number of digits of a caller's phone number that the subscriber phone can capture or display.
   Max DNIS digits	Telephone companies can provide a dialed number identification service (DNIS) that lets the receiver of a call know which number the caller has dialed. Enter the number of digits of a dialed call that the FortiVoice phone system sends to the telephone company.
