[Asterisk-Users] Busy message on ISDN cards?

[Andrew Furey]

Hi all,

I'm new to asterisk and not too knowledgeable on ISDN, so please be gentle :)

I have a dual-channel Eicon Diehl Diva card in a Debian Woody box with
kernel 2.4.27, connecting to a Telstra (Australia) Onramp Home Highway
ISDN line. I'm pretty certain the card and line both work since
they've been used in this machine for PPP before this (but with an
older kernel with DoV patches, which are no longer to be used).


If I do

# modprobe hisax type=11,11 protocol=2,2 id="HiSax"

it responds (in the syslog) with:

kernel: ISDN subsystem Rev:
1.1.4.1/1.1.4.1/1.1.4.1/1.1.4.1/1.1.4.1/1.1.4.1 loaded

kernel: Eicon.Diehl Diva: IRQ 9 count 1705
kernel: HiSax: DSS1 Rev. 1.1.4.1
kernel: HiSax: 2 channels added
kernel: HiSax: MAX_WAITING_CALLS added

so it appears to be detected. I'm using the following modem.conf:

[interfaces]
context=remote
driver=i4l
language=en
type=autodetect
dialtype=tone
mode=immediate

group=1
msn=91234567
incomingmsn=*
device => /dev/ttyI0


Starting asterisk with -vvvvc returns:

 == Parsing '/etc/asterisk/modules.conf': Found
[chan_modem.so] => (Generic Voice Modem Driver)
 == Parsing '/etc/asterisk/modem.conf': Found
 == Loading modem driver chan_modem_i4l.so => (ISDN4Linux Emulated Modem Driver)


But if I define a test extension such as:

TRUNK=Modem/g1
exten => 2468,1,Dial(${TRUNK}/91234567:0412345678)

and try to dial it, the console says:

Dec 14 13:29:17 WARNING[15375]: chan_modem_i4l.c:608 i4l_dial:
Outgoing MSN andrew not allowed (see outgoingmsn=,, in modem.conf)
    -- Called g1/91234567:0412345678
    -- Modem[i4l]/ttyI0 is busy
    -- Hungup 'Modem[i4l]/ttyI0'

I gather than "busy" is used for pretty much everything except for no
connection, but are there any suggestions of where to look?

Thanks in advance,

Andrew
