goto_on_blindxfr

I am trying to use


exten => s,n,set(GOTO_ON_BLINDXFR=parkthecall^s^1)


[parkthecall]


but when i m pressing the blindtransfer key set in features.conf, i only hear “transfer” n then a tone which expects me to manually enter some extension…
its not jumping to the specified context…

can anyone have an idea??
