Remote Site with its own CUCM Sub#2 and Router network failed and the site didnt keep its phones active, need some assistance

I have a Pub and 2 Sub's.  Sub #1 is with the Pub, at the main site it is our TFTP server, Sub #2 is at a remote site with about 100 users along with a router and 2 PRI's for outbound calls.  We had a network failure between the main site and the remote site and all phone lost their registration with the system until we were able to get the network back up.   Currently the network is up in a crippled state on a 1 T-1 link while we troubleshoot the bigger issue with our 6mb pipe, however Sub #2 and its associated router arent talking with the PUB or other Sub.  I'm still getting alerts every 30 minutes stating they are the server is down.  I'm sure once the network is corrected this will bring everything back on line.  My question is how can I prevent in this in the future.  I need this site to be stand alone if the network goes down again.  I was told by our vendor that if we had a subscriber at each site then we would need SRST licensing. I know something needs to be configured to make it all work, I'm just not sure what.

Configure a separate CUCM

Configure a separate CUCM group for the remote site with just the PUB that is local to them.

I already have a group at the

I already have a group at the site but it includes both the Pub and Sub from the main site as well as the Sub from the remote site.  I would only have to remove the Sub from the main site, problem is I currently only have 1 TFTP server it runs on SUB #1, should I make SUB#2 a TFTP server as well and the phones are setup for DHCP at the main site, I'm going to need to have a DHCP server setup at the remote site as well. Correct?
