thanks for the reply...you seem very familiar with fone tek... I'm sys admin... I come from opensource sip/voip background so Vendor hardware pbx solutions are kind of new to me the service is great from russell comm but we have had a few issues..not really sure what the root is.
its seem ro be pretty error proof...considering the system will still work inbound/outbout if the server crashes, we just loose call attendant features...
any ideas on how we can build redundancy into our current config?
current is MPLS network T1's to 27 locations shortel switch
Do you have to have voicemail server at every local?
and we may run backhaul DSL to CO.
