IMHO adding ser/opensips/kamailio for a 100 seat setup would just
complicate your installation.

Considering the question you are asking and the fact your installing for
a call center which needs high availability, for your own sanity, I
would suggest you do hand it over to a Pro (whether the price is right
There are many ways to make asterisk more 'highly available' but you
need to determine the exact requirements of the call center before
recommending a solution, it may be for your specific case a 'hot
standby' would be enough - an Asterisk install should be very stable
running a good quality server with raid1 and a UPS. If you want live
failover you could implement a two node cluster using heartbeat and
DRBD. You might also like to look at separating gateway devices from the
core PBX node, for example if using separate ISDN PRI interconnects you
might choose to have independent asterisk servers providing SIP bridging
or use commercial SIP gateway hardware. You can also split the core PBX
functions and bridge Asterisk servers or use MySQL replication for
sharing live dial plans etc..etc..
Most importantly don't forget VoIP security.
