Hi Matt,
If Asterisk 4 is down, the hash will not be recalculated, but the calls
that should go to Asterisk 4 will simply be pushed to the next available
entry in the dispatcher list.
Regards,
Bogdan

I'm new to dispatcher - wanted to clarify couple of things...
I'm using algorithm 7 (hash over the content of PVs string) to pick a
destination.
modparam("dispatcher", "hash_pvar", "$pvar")
ds_select_dst("1", "7");
Let's say the probing_mode is 1, and based on the value of $pvar (A,
B, C, etc.), incoming requests are dispatched in the following fashion:
A -> Asterisk1
B -> Asterisk1
C -> Asterisk2
D -> Asterisk3
E -> Asterisk4
F -> Asterisk4
What happens to E, F if Asterisk4 fails? Are they distributed among
the remaining servers or do they all go to the same server?
Do A, B, C, D still go to the same servers? In other words, is the
hash recalculated?
Can hash_pvar be changed; e.g. use $si for route[1], use $ci for
failure_route[1]?
Thanks,
Matt
