<DIV><SPAN class=583264717-13022008><FONT face=Arial size=2>I currently have
multiple Asterisk servers using Sangoma A104d Quad ISDN
E1s.</FONT></SPAN></DIV><SPAN class=583264717-13022008>
<DIV><BR><FONT face=Arial size=2>Basically our telco is presenting calls in
order of the ISDNs on our servers.</FONT></DIV>

<DIV><SPAN class=583264717-13022008><FONT face=Arial

<DIV><SPAN class=583264717-13022008><FONT face=Arial size=2>We have redundancy
in that if SERVER1 is shutdown then each ISDN PRI is in alarm and the calls will
then presented to PRIs 5,6,7,8 on SERVER2.<BR><BR>If I have to take SERVER1
offline for maintenance (asterisk -rx shutdown gracefully) any incoming
calls receive a BUSY tone.<BR><BR>What I would like to know is if there is
anyway to get around this and not send a BUSY back to our callers and somehow
allow our telco to present calls immediately to SERVER2.<BR><BR>Anyone have any
ideas or are we stuck with this behaviour until the calls drop to 0
and Asterisk shuts
down ?<BR><BR>Thanks,<BR>Andrew</FONT></SPAN></DIV>
