I haven't actually used that script, but it shouldn't sit there forever.
Take a look at what each of the arguments mean:

https://freeswitch.org/confluence/display/FREESWITCH/Lua+API+Reference#LuaAPIReference-session:playAndGetDigits

In the example, session:playAndGetDigits will wait 2 seconds for an
entry and then increment the attempts if unsuccessful. On the third
unsuccessful attempt, digits will be "". Since digits won't be "1" or
"2" the script will session:hangup("NO_ANSWER").

If whatever picks up the call can't dial digits, the call should hangup
after 6 seconds.
