Bei Anruf einmal klingeln, dann Stille

[Marvin32]

Hallo,

ich habe neben ein paar anderen Problemchen folgendes großes Problem:

Wenn ich von außen mit meinem Handy ein Softphone anrufe, klingelt es einmal. Dann höre ich als Anrufer ein schrilles "tuten" danach herscht Stille.

Aufbau ist folgender:
NTBA--->Auerswald 2206 TK Anlage --int. S0-->Asterisk--->Xlite

Meldung im CLI ist folgende:

*CLI>   == ISDN1#02: Incoming call '001754909xxx' -> '41'
    -- Executing [41@capi-in:1] Dial("CAPI/ISDN1#02/41-1", "SIP/2000") in new stack
    -- Called 2000
    -- SIP/2000-081f8b30 is ringing
       > ISDN1#02: CAPI INFO 0x349a: Non-selected user clearing
  == Spawn extension (capi-in, 41, 1) exited non-zero on 'CAPI/ISDN1#02/41-1'

meine extension.conf

[default]

[fhf]
include => interne-anrufe
exten => _X.,1,Dial(CAPI/ISDN1/51:${EXTEN})

[interne-anrufe]
exten => _200X,1,Dial(SIP/${EXTEN})

[capi-in]
exten => 41,1,Dial(SIP/2000)

und die capi.conf

Vielleicht ist dieses Verhalten ja bekannt.
