[SOLVED] problem asterisk-iaxmodem-hylafax-adsl line

helo everyone,
I’ve finished to configure my server VoIP on an ubuntu 8.04lts and asterisk 1.6.1.6.
Now I’d like to setup asterisk to send and receive fax using an ADSL line, to make that I want use iaxmodem and hylafax.
I’ve followed this howto

the-asterisk-book.com/unstab … -empfangen

But when try to check the connection between asterisk and iaxmodem with iaxmodem ttyIAX0 receive an error of connection “Registration failed”.
Is there someone that could help me to resolve that problem?
thanks in advance

I’ve add the line

requirecalltoken=no

to the file iax.conf

I set
host=dynamic
in the iax.conf for [iaxmodem] and it helped
