I’ve 1 PRI ISDN used via chan_modem, 3 register lines into sip.conf, 6 voip phone.
If i start asterisk and the ADSL is down the 6 voip phones are unable to call each other and also to place call via ISDN because they are not registered.
No it does not works, i’ll give a try putting fixed ip address into /etc/hosts
is this all the problem? i dunno … it seems that asterisk will not go onto the other phone registration until the first “register =>” are completed.
