Hi, I wonder how feasible is the folowing:
I have a regular expresion like:
REGEXP = "^((1|20)|(13|3|4)|(5|6))"
There are 3 matching groups:
1) (1|20)
2) (13|3|4)
3) (5|6)
I want to match the RURI user, let's suppose $rU = "138787686223". In
this case the above regexp matches groups 1 and 2, but since group 2
matching is longest ("13" is longest than "1") I want to get value 2.
In case $rU = "999999" I need to get "null", in case $rU =
"1000022323" I need to get "1".
AFAIK there is no way to do it with current regular expression utils
in Kamailio, but maybe I miss something. Thanks a lot.

one option that comes in my
mind is to break it in several if
conditions, matching one group at a time, written in the order of
preferences.

The problem is that it would require perform N regular expression
matching and such expressions will be very long (all the country
prefixes in the world). The main problem is that some groups would
contain prefixes starting with, for example, 12, while in other group
there is the prefix 1 (an the very same in multiple cases, so doing it
manually would be too much manual work and any change in the world
would require hard modifications).
I'm evaluating building a custom function for this purpose.

perhaps you could use dialplan module. it there is overlapping regular
expressions, one is selected based on its priority.

Thanks. I don't need different priorities, I just need that, in case
of multiple matching (i.e. ^1 , ^10) the longest matching wins. Does
the dialplan module allow it? By reading the doc it seems that it's
not possible, so I should need to assign lower priority to those
shorter country prefixes. It could be a solution however.
Thanks to both.

Yes, the trick will be:
priority = 20 - strlen(match_exp)
so longest expressions would have higher priority.

Hi Iñaki,
if you just want to have the longest match on a prefix tree, this is what
carrierroute was build for.
In case $rU = "999999" I need to get
"null", in case $rU =
"1000022323" I need to get "1".
Its works a bit differently, but this is similar to the logic that we use.
You've a bunch of specific prefixes with special routing, normal country
prefixes that you want to route differently and then a default routing for the
rest.
Best regards,
Henning

Thanks Henning. I do know that CR and LCR operate with longest prefix
matching, but I don't want this feature now for routing purposes, but
for blacklist purposes. So using dialplan module with higher
priorities in longer prefixes would be valid in my case.
Thanks a lot.

It's not valid for my custom case as I need a function returning an id

1: Europe (prefixes of Europe)
2: North America (prefixes of North America)

Yes - the dialplan is much more flexible of course. :-)

Well, for sure cr and userblacklist implements regular expression
matching by taking the prefix from the DB and internally using
"^PREFIX" (I expect). Same as LCR.
The fact is that I don't need more regular expressions than that. This
is, I don't need to set a prefix like "(1|2[0123]{2})". :)

Hello Iñaki,
I did this a long time ago using a db backend, i can't remember exactly how.
the table would be:
areacode, route
1 route1
13 route2
I connected to mysql and ran something like:
select * from routes where '$rU' like concat(areacode,'%') order by
len(areacode) desc limit 1;
that works perfectly
hope it helps

Hi David, that would work indeed, but I prefer not to saturate the DB

2000-3000 concurrent calls and such calls come from callcenters so
they are very "aggressive" (maybe 200-300 calls in the same second),

Hello Iñaki,
I had much the same traffic, and with a good index that wouldn't be a
problem, IMHO.
You could also load the table in memory, can't be faster than that.
Of course, doing it in the config script is faster, but it limits your
flexibility... just a thought...
I even got the rate and created a "custom" cdr for each call. we had around
4k concurrent calls at that time (like 5 years ago)
Anyway, good luck!

Hi David, your query cannot make usage of table indexes:
select * from routes where '$rU' like concat(areacode,'%') order by
len(areacode) desc limit 1;
You are using "LIKE" and concat(TABLE_COLUMN...) so you are forcing
the database server to read *all* the values of "areacode" (all the
rows), create a new string by concatening "%" at the end, and then
performing a regular expressión (LIKE "XXX%") for *every* resulting
values. This can never use an index.
You can check it by yourself by entering into mysql console:
DESCRIBE select * from routes where '999999999' like
concat(areacode,'%') order by len(areacode) desc limit 1;
You will realize that no index is being used.
You could also load the table in memory, can't be
faster than that.
Yes, but for that a custom module is required :)
Of course, doing it in the config script is faster,
but it limits your
flexibility... just a thought...
Humm, in fact not. I can manage the table content via a web interface
(or whatever) and running a MI "reload" command for the used module so
the table content is read again into memory. This is the same as I do
with LCR module and others.
Regards.

The module can load on
db table in a memory tree or one db table in many
trees. For the second case, the db table name is a module parameter and
in addition it must have an extra column to specify the memory tree name.

Thanks
Daniel, please let me one question more: does the mtree module
allow setting two different tables (with maybe also different columns
names)? The function mt_match(mtree, pv, mode) seems to allow, as
first argument, the "model/table" to use, but I see no way of defining
different models, is it?
Ok, it seems that using "mtree" parameter does
the job (but columns
must have same name in all the tables):
modparam("mtree", "mtree",
"name=mytable;dbtable=routes;type=0;")
6:37 p.m.
New subject: Using =~ to get the group identifier with longest match

The module can load on db table in a memory tree or
one db table in many
trees. For the second case, the db table name is a module parameter and in
addition it must have an extra column to specify the memory tree name.
Great. So we can extract different mtrees from the same table, just by
filtering by tname column (and then using the assigned name for the
module function). Just great :)
Thanks a lot.

yes columns names are configurable
per module -- maybe in the future
will be per mtree.
Meanwhile maybe you can use mysql views to get to the column names
expected by mtree.
Cheers,
