[asterisk-users] DUNDi precache

[Bruce Reeves]

Doug,

JR's example does cache but only for a very short time, like 5 seconds, so
that if the device registers else where then the lookup is able to find it.
You can change the cache time to the default hour or what ever you want. As
far as precahe, I know it is a dundi cli command and you could probably
script connecting to the cli and precacheing an extension, but in my case
the lookups are under 70 ms so I don't notice a hughe hit on performance
when a lookup is done. I know you are trying to use this on a much larger
scale then I do.
