[asterisk-users] Submenus

[Mojo with Horan & Company, LLC]

Try breaking up the contexts. Contexts are what you call 'submenus'. 
For example:

[MetarMain]
exten => 1,1,answer
exten => 1,n,Background(Met_welcome)
exten => 1,n,Background(Met_Instructions)

exten => 3575,1,set(airport=ekrk) ; non-ambiguous
exten => 3575,n,goto(Metar_Process,s,1)

exten => 3524,1,goto(Metar_ekch_ekah,s,1) ; ambiguous, so submenu

[Metar_ekch_ekah]
exten => s,1,Background(Metar_ekch_or_ekah)
exten => s,n,WaitExten(3000)
exten => s,n,goto(1)

exten => 1,1,set(airport=ekch)
exten => 1,n,goto(Metar_Process,s,1)

exten => 2,1,set(airport=ekah)
exten => 2,n,goto(Metar_Process,s,1)

[Metar_Process]
exten => s,1,NoOP(Airport code chosen: ${airport})
exten => s,n,...

Made it up as it went along, so it could be strewn with bugs... but it 
should lead you in the right direction.
