Premature end of call

When I make an outgoing call from my trixbox, only ring four or five times and then stop ringing. I want to let a voice message in the other phone but I can't because the call stop before the voicemail start.

I can see in the log that the asterisk get busy signal:

Zap/5-1 is busy
-- Hungup 'Zap/5-1'
== Everyone is busy/congested at this time (1:1/0/0)
-- Executing Goto("IAX2/998-1", "s-BUSY|1") in new stack
-- Goto (macro-dialout-trunk,s-BUSY,1)
-- Executing NoOp("IAX2/998-1", "Dial failed due to trunk reporting BUSY - giving up") in new stack

I can't understand because the call rings 5 or 6 times befora get busy signal...

If I connect the isdn line to a isdn phone directly I can call and the ring don't stop.

Can you helpme?

Thanks.

hello, usuarioforum:
from your message, i guess that your dialplan has problem and make sure the zap5 also is available.

The channel is available. If someone answer the call it works. Is when nobody answer the call that stop ring so early...

For some reason the spanish analog lines send a tone and asterisk think that is a busy tone. You only must to put:

busidetect=no

in zapata

Cheers.
