applicationmap не срабатывает у звонящего

Привет. подскажите, почему может не работать application map для звонящего? extensions.conf

exten => 19999999999,1,Answer()
exten => 19999999999,n,Set(__DYNAMIC_FEATURES=skipRecording#playmonkeys)
exten => 19999999999,n,Wait(60)
exten => 19999999999,n,Hangup()

features.conf

[applicationmap]
playmonkeys => #9,peer,Playback,tt-monkeys

также пробовал playmonkeys => #9,self/both,Playback,tt-monkeys

При вводе #9 звонящим ничего не проирывается и нет попыток отработать featurecodt логику. вот логи из консоли:

При этом, что интересно, если второе плечо подключить - то у него все работает.
