1. If the other end picks up the phone the conversation is successful and when
the conversation ends, the channel is properly released:
-- CAPI/ISDN1#02/2104988888-0 answered SIP/1000-081d91b0
== ISDN1#02: CAPI Hangingup for PLCI=0x101 in state 2
== Spawn extension (internal, 2104988888, 1) exited non-zero on
'SIP/1000-081d91b0'
> ISDN1#02: CAPI INFO 0x3490: Normal call clearing
2. BUT: If I hangup the softphone before someone answers, I get:
== ISDN1#02: CAPI Hangingup for PLCI=0x101 in state 5
and the 1st channel is left occupied:
atlas*CLI> capi show channels
CAPI B-channel information:
Line-Name NTmode state i/o bproto isdnstate ton number
----------------------------------------------------------------
ISDN1#02 no discP O trans *P 0x00
'1000'->'2104988888'
ISDN1#01 no ----- - trans 0x00
''->''
If I call again and hangup before someone answers, the 2nd channel is used and
then left occupied:
atlas*CLI> capi show channels
CAPI B-channel information:
Line-Name NTmode state i/o bproto isdnstate ton number
----------------------------------------------------------------
ISDN1#02 no discP O trans *P 0x00
'1000'->'2104988888'
ISDN1#01 no discP O trans * 0x00
'1000'->'2104988888'
