Script to configure distinctive tone for FXS port

Description

In some particular scenario, you might want to distinguish ringing tone for internal and external calls on an analog phone.

For example:

When there is internal call to analog phone, play default ring cadence.

When there is inbound call from outside to analog phone, play personalized ring cadence.

Applicable Device

Device Model: P-Series, S-Series

Firmware Version: Not required

Code for S-Series

[macro-stdexten-fromoutside]
exten = s,1,Set(IsFromOutside=1)
exten = s,n,Set(PBXDIALNUM=${ARG1})
exten = s,n,ExecIf($[${LEN(${CALLERNUM})}=0]?YsWalkContext(whitelist-inbound,${PBXDIALNUM},1,${CALLERID(num)},inbound)
exten = s,n,Noop(Distinctive Ringtone for Inbound Calls to Analog Extension)
exten = s,n,GotoIf(${LEN(${FILTER(D,${ARG2})})}>0?+1:+4)
exten = s,n,Noop(Target is Analog Extension)
exten = s,n,Set(ARG2=${ARG2}r17)
exten = s,n,Goto(10)
exten = s,n,Noop(Target is not Analog Extension)
exten = s,n,Macro(realstexten,${PBXDIALNUM},${ARG2},${DIALOPTIONS})

Code for P-Series

[macro-stdexten-fromoutside]
exten = s,1,Set(IsFromOutside=1)
exten = s,n,ExecIf($[${LEN(${SRCTRUNKNAME})}>0]?Set(FORWARDPREFIX=EX))
exten = s,n,Set(PBXDIALNUM=${ARG1})
exten = s,n,Gotoif($["${TOFORKCDR}" != "yes"]?walk_ctx)
exten = s,n,Set(CDR(transfertype)=dial)
exten = s,n,ForkCDR(erv)
exten = s,n,Set(CDR(callflow)=ext)
exten = s,n,Set(TOFORKCDR=no)
exten = s,n(walk_ctx),YsWalkContext(whitelist-inbound,${PBXDIALNUM},1,${CALLERID(num)},inbound)
exten = s,n,Noop(Distinctive Ringtone for Inbound Calls to Analog Extension)
exten = s,n,GotoIf(${LEN(${FILTER(D,${ARG2})})}>0?+1:+4)
exten = s,n,Noop(Target is Analog Extension)
exten = s,n,Set(ARG2=${ARG2}r17)
exten = s,n,Goto(16)
exten = s,n,Noop(Target is not Analog Extension)
exten = s,n,Macro(realstexten,${PBXDIALNUM},${ARG2},${DIALOPTIONS})

r17 in the code is the personalized cadence from output of command asterisk -rx 'dahdi show cadences', it's only possible to choose any one available from the output.
