Rick,

The default 24 hour time limit is 30 minutes for most PMBOs, however, 
this varies with the specific PMBO. Any PMBO will grant additional 
time upon request.

Scamp is in a holding pattern since much work is being done to 
eliminate the primary central server/backup central server in favor 
of Common Message Servers, which all run redundantly with mutliple 
phase commits. In other words, should one Common Message Server go 
down, the Radio Message Servers (PMBOs) automatically route to the 
remaining Common Message Servers. Currently, there are two in 
production and one more testing, but we will quickly to a five server 
system. 3 in the US, one in Eu and one in Aus.

I know that Rick, KN6KB, is also looking at some basic changes to 
SCAMP, but I do not know more.

FYI,


Steve, k4cjx
