[Asterisk-Users] Busy message on ISDN cards?

[Eduardo López Martínez]

Hi all,

I'm experiencing some problems with i4l and i can't find a solution. I'm
using
	
	Eicon Diva 1 BRI
	Eicon Diva Server 4 Bri
	A ISDN PBX where I connect the first ISDN card (exten 204 in the
ISDN PBX) and a ISDN phone (exten 210 in the ISDN PBX)
	Suse 8.1 with ISDN4Linux
	Asterisk 1.0

I'm trying to make phone calls from a softphone (Windows Messenger 4.6) to
the ISDN phone but I get this:

Asterisk Ready.
*CLI>     -- Executing Dial("SIP/edu-ee6e", "Modem/g1/204:210") in new stack
Urgent handler
Jan  1 18:51:19 WARNING[29364]: chan_modem_i4l.c:601 i4l_dial: Outgoing MSN
edu not allowed (see outgoingmsn=,*, in modem.conf)
    -- Called g1/204:210
Urgent handler
    -- Modem[i4l]/ttyI0 is busy
Urgent handler
    -- Hungup 'Modem[i4l]/ttyI0'
Urgent handler
Urgent handler
  == Everyone is busy/congested at this time
  == Auto fallthrough, channel 'SIP/edu-ee6e' status is 'CHANUNAVAIL'
Urgent handler


I see how the modem activates using imon (ISDN monitor) and tries to
connect.
When I add "outgoingmsn=edu" in modem.conf the modem does not respond, and I
get the following:

Asterisk Ready.
*CLI>     -- Executing Dial("SIP/edu-c490", "Modem/g1/204:210") in new stack

Calls from the ISDN phone to a softphone WORK.

Can anyone help me??? Thanks in advance ;)
Eduardo.
