Another good transition tool to play with may be mod_dialplan_asterisk which
is in tree.

Once loaded in modules.conf.xml it can be used in your sofia profile by
adding "asterisk" as the dialplan parameter.
You can also transfer calls to it by specifying it as the dialplan param in
the transfer or execute_extension apps.

it's not entirely like the real asterisk dialplan but it is at least a close
familiarity.
You cannot include contexts in each other in ours because we do all our
dialplan logic before the call.

It's structured in the same way so you can create context default

[default]
; and you can use comments the same way
; here is a demo that is close to the extensions.conf in tree that installs
by default

------------------
[default]

; Things you're used to....
exten => music,n,Dial(SIP/1234 at conference.freeswitch.org|120)

; similar pattern matching and caller-id match.
exten => _1XXXXX,n,set(cool=${EXTEN})
exten => _1XXXXX,n,set(myvar=true)
exten => _1XXXXX,n,Goto(default|music)
exten => 2137991400/1000,n,Goto(default|music)

; we also embellished things a bit and added some of our own goodies
; Some new magic you can do.... if you start the exten string with a ~ it
implies PCRE regex
; *NOTE* the ,n, is there for familiarity purposes we do not parse it anyway
nor will we honor line numbers.

exten => ~^(18(0{2}|8{2}|7{2}|6{2})\d{7})$,n,enum($1)
exten => ~^(18(0{2}|8{2}|7{2}|6{2})\d{7})$,n,bridge(${enum_auto_route})

; instead of exten, put anyting about the call you would rather match on.
; either the names of a field in caller_profile or a string of variables to
expand.
caller_id_number => 2137991400,n,Goto(default|music)
${sip_from_user} => bill,n,Goto(default|music)


Anyway you will find the XML dialplan more flexible but this may serve as a
stepping stone for beginners.
