If a part in a CUCM server died (RAM, mobo, HD, CPU) you could theoretically have that part replaced within 4 hours. Then you'd have to perform an install and DRS restore if it was a catastrophic HD/RAID failure (otherwise when the part was replaced you'd be good to go). If you do a good job this could probably all be done during the course of one business day.<br>
<br>SRST could certainly handle the PRI for you while the CUCM server was down. You'd have to look at the sizing though for how many phones a 2801 can handle in SRST.<br><br>Which looks like 24 phones in table 4<br><br>

I am trying to create a "what if" scenario, and how we would react. Obviously, with SmartNet and all that, you can minimize some issues, but if a CM box were to die (and we only have one), getting a new one could be quick, but getting it all installed and everything else could be lengthy. <br>
<br>So I am wondering what you would recommend:<br><br>We have an ISDN coming in to a 2801 in H323 mode. Most calls come in on this and most go out this line as well.<br>At a remote site, connected by fiber, we have a 2801 with SRST and two POTS lines plugged into FXOs.<br>
Now if my CM were to die, could users still go out the ISDN, or does CM handle that? Could I route calls in from the ISDN somehow, or again, is that something CM handles?<br><br>I am just trying to plan for the worst and hope for the best!<br>
<br>Thank you for any suggestions (and setting up a Pub/Sub is an option, but not one in the current budget picture).<br>
