[Asterisk-Users] Problem with dial out via chan_capi

[Kib Eki]

Hi *,

we successfully integrated the eicon diva 4 bri card in our Asterisk system.
I can dial in to system and route to sip peers.

I tried to dial out with following configuratin without any luck:
extensions.conf:
   exten => _5.,1,Dial(CAPI/@301:b${EXTEN})

capi.conf:
[general]
mode=immediate
isdnmode=multipoint
nationalprefix=0
internationalprefix=00
rxgain=0.8
txgain=0.8

[interfaces]
msn=301
incomingmsn=*
controller=2
context=default
echocancel=1
echotail=64
devices=2


Console output as follow:
     -- Executing Dial("SIP/bdk-d27c", "CAPI/@301:b5030225476") in new stack
     -- Called @301:b5030225476
     -- Setting up echo canceller (PLCI=0x102, function=1, options=2, tail=64)
     -- Echo canceller successfully set up (PLCI=0x102)
     -- CAPI Hangingup
   == No one is available to answer at this time


Can you help me or give me tips?

Thanks in advance.
