Hi Juha
based on my experience with the mtree module:
-mt_match() will match the longest prefix in the tree, in your case 00358
* yes, longest prefix is matched
-mt_ignore_duplicates makes sense when loading the data in the DB to
the memory. There could be duplicate entries in the db and with that
directive you tell kamailio how to handle that situation
* indeed, duplicated are ignored in such mode, otherwise loading the
records from db will throw error in duplicate prefixes.
-I don't know about mt_tree_type...(never needed to test it)
* this is intended to control the behavior of the tree data and matching
mode. The default one is 0, match longest prefix and the associated data
with the prefix is a string. This is complete implementation.
There is actually a second mode, 1, intended to have the data as two
integers separated by colon, like 'weight:value' iirc. The matching of
any part of the prefix that has data associated with will add 'value'
into a list of avps ordered by 'weight'. Since it was not really tested
and the implementation might not be full -- due to lack of time at that
moment and plans to migrate to use xavp for proper internal
representation -- it was left undocumented. I should review this mode soon.
Other types of trees may be added in the future in order to optimize the
data in the nodes for runtime usage.
Cheers,
Daniel
Hope it helps

after reading mtree readme, it is not clear to me if mt_match()
matches
to longest or any matching prefix in the three. for example, if i
have
tree with prefixes 00 and 00358 and string to be matched is
0035892345670, will mt_match() set pv to value associated with 00 or
00358? also, if mt_ignore_duplicates is set, will 00358 be considered
as duplicate of 00 or just prefixes that are exactly same. finally,
what are possible mt_tree_type values and what types they stand for?
