A dialplan entry on the pbx.shifteight.org system might look like this:

[unauthenticated]

exten => leif,1,Goto(PublicExtensions,100,1)

exten => jim,1,Goto(PublicExtensions,101,1)

exten => tilghman,1,Goto(PublicExtensions,102,1)

exten => russell,1,Goto(PublicExtensions,103,1)

This is by far the simplest way to implement name dialing, but it is also complex to

maintain, especially in systems with hundreds of users.

In order to implement name handling in a more powerful way, you could add something

like the following to your extensions.conf file. Note that some lines have been wrapped

in this example due to space restrictions. These lines must appear on a single line in

the dialplan. All lines should start with exten =>, same =>, or a comment indicator (;).

[unauthenticated]

exten => _[A-Za-z0-9].,1,Verbose(2,UNAUTHENTICATED REQUEST TO ${EXTEN} FROM

${CALLERID(all)})

same => n,Set(FilteredExtension=${FILTER(A-Za-z0-9,${EXTEN})})

same => n,Set(CheckPublicExtensionResult=${DIALPLAN_EXISTS(PublicExtensions,

${FilteredExtension},1)})

same => n,GotoIf($["${CheckPublicExtensionResult}" = "0"]?CheckEmailLookup)

same => n,Goto(PublicExtensions,${FilteredExtension},1)

; This is our handler for when someone dials a SIP URI with a name

same => n(CheckEmailLookup),GoSub(subEmailToExtensionLookup,start,1

(${TOLOWER(${FilteredExtension})}))

same => n,GotoIf($["${GOSUB_RETVAL}" = "NoResult"]?i,1:PublicExtensions,

${GOSUB_RETVAL},1)

same => n,Goto(i,1)

; This handles invalid numbers/names

exten => i,1,Verbose(2,Incoming call from ${CALLERID(all)} to context ${CONTEXT}

found no result)

same => n,Playback(silence/1&invalid)

same => n,Hangup()

; These are explicit extension matches (useful on small systems)

exten => leif,1,Goto(PublicExtensions,100,1)

exten => jim,1,Goto(PublicExtensions,101,1)

exten => tilghman,1,Goto(PublicExtensions,102,1)

exten => russell,1,Goto(PublicExtensions,103,1)

When a call enters the dialplan, it can match in one of two places: it can match our

pattern match at the top, or it can match the explicit named extensions closer to the

bottom of our example (i.e., leif, jim, tilghman, or russell).
