[ILUG] High Availability Asterisk

[Kevin Brennan]

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 
or not).

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.
