Hi,
I'm having some interesting results with using the ds_select_dst
function to load balance asterisk boxes. I.e. packets with
method==INVITE are routed with ds_select_dst.
when using two destinations in the dispatcher.txt file, the calls get
disproportionately sent to one destination, unless i'm using the
callid hash. However callid's property of changing with every invite
(reinvite, etc) causes me to question it's suitableness.
re-INVITE must have
same call-id -- it is message within dialog.
For example:
A calls B, puts B on hold, takes B off hold. Error prone or not?
Not.
A calls B, puts B on hold, calls C, conferences.
Ad nauseum.
Am I missing something?
Is there a better approach?
You should route the calls within dialog based on
Record-Route/Route
headers, not with dispatcher.
Should it Just Work, even hashing on callid?
As
said, callid must be same for all messages of a call. Should work.
There is also round-robin, if the distribution based on hash does not
give good results.
Cheers,
Daniel
