Hi,
I some calls to a specific `sub-region` that I want to limit to a
specific trunk. Example.
Region 1: prefix 55, trunk 1, priority 10
Region 1: prefix 55, trunk 2, priority 20
Sub-region A: prefix 5512, trunk 1, priority 30
I do not want the calls to prefix 5512 to fail-over to trunk 2 in case
of 404, 503 or the like. So I have tried to put priority 30 on
sub-region A and a lower priority on Region 1, but it still fails over
to trunk 2 - can I prevent this?
Thanks!

That is not possible with lcr in 1.5.X, but AFAIK it's possible in 3.X
by setting the "stopper" flag to the rule with prefix 5512 (so no
other rules are loaded after this one).
A workaround would be setting a specific value in the "From" field of
the rule (i.e. "no-failover") and calling "load_gws" using such
stirng
as parameter. But it's a bit ugly (very ugly) as requires modifying
the script.

hmm - so I really need to start considering migration plans to 3.X!! :-/
Talking about ugly solutions - maybe this could work: The from_uri in
lcr always shows the domain name I have given to my customers - to
where they send calls. So I could create a new domain name (pointing
to the same IP), and then ask the customer to send to this domain -
and then in lcr I would put the new domain in the from_uri, and make
prefix with no failover for that domain. So there would be a
`fail-over-free` solution if calls are sent to a specific domain.
Would that work?
Thanks again!

it would, but only if you would have from pattern defined for each
rule.
3.x also allows to you define lcr instances, which are totally
independent from each other. you could assign an lcr instance to the
request based on from which customer the request comes from.

This whole 3.X migration is starting to sound quite appealing!
But back to solving the immediate issue: You say I would have to have
the from_uri defined for each rule. What about the ones that are
current null, would they be included in any from_uri definition?
Meaning that after trying with the rule where the from_uri matches, it
would fail-over to where the from_uri is null? (maybe I should stop
asking questions and do the test!)

So the client should use a specific From domain when it calls to 5512
prefix and another From domain when it calls to other 55 prefix.
Unfeasible and weak solution IMHO as it fully depends on the client
behavior.
What I really suggested in my mail (for the 1.5.X version) is ignoring
the From domain of the INVITE and specify a "from" value as
*parameter* when calling "load_gws()".

Yes, I kind-of understand it...just trying too see if I could find an
easier way around.
Thanks for all the input!!

anders,
sr 3.1 allows you to define that a rule is a "stopper" rule meaning that
if that rule matches, no other (lower priority or shorter prefix) rule
will be tried.

Hi Anders,
you probably will need to create this 5512 prefix for trunk 2.
This logic of including only the same length prefixes for re-routing has
its pluses and minuses.
Maybe someone else can share their practices for re-routing with lcr?

Hi Antanas,
Great idea - I'll try that solution - makes a lot of sense.
Thank you!
