Hi, I am having problems adding a JACK_HOOK function to a Asterisk dialplan. I have jackd (1.9.10) running. And tested. in extensions.conf I have the following plan: exten = 99,1,Answer() same = n, Set(JACK_HOOK(manipulate,s(default),i(system:playback_1))=on) When I set a peer to call it (from Keriga), the Asterisk console, prints: -- Executing [99 at home:1] Answer("SIP/1002-00000033", "") in new stack -- Executing [99 at home:2] Set("SIP/1002-00000033", "JACK_HOOK(manipulate,s(default),i(system:playback_1))=on") in new stack [May 11 21:55:26] NOTICE[6526][C-0000004e]: app_jack.c:192 log_jack_status: Client Open Status: Failure, Server Failed -- Auto fallthrough, channel 'SIP/1002-00000033' status is 'UNKNOWN' I don't understand why does "Client Open Status: Failure, Server Failed" appears. And also 'SIP/1002-00000033' status is 'UNKNOWN'. When checking jack_lsp I can only see the system ports, but no Asterisk port. Any hints on how I could solve this are appreciated.
