Hello Daniel,
indeed dialplan could solve this. But i dont follow that because i dont
want to manipulate the $rU part.
So for my usecase as siprouter to route "comes from X goes to Y, comes from
Z goes to A" i use permissions module (comes from) and dispatcher (goes to)
.
Thanks for the drouting statement. Its okay. I was trapped by the db-field.
I try it and saw later that it was not the module i need.
Kind Regards

Hi List,
i answer myself if someone search for the same problem and ends with no
solution.
Short answer to "drouting" based on "alphanumeric" prefix question is
- NO.
Only numbers are allowed, maybe a + sign, i dont check that.
answered by Dmitri in another response, the chars allowed in prefix are
the digits, +, * and #.
Anyhow, even making it configurable, if you want to allow all the
alphanumeric chars in the prefix, the indexing of the prefixes becomes
inefficient, at least from memory point of view. The module uses tree
indexing for prefixes and each node is composed by so many items as
possible chars in the prefix, so the node size is going to be big if you
have lot of possible chars in it.
The usual solution in this case is to have two layers of indexing. Use
htable or dialplan modules to map between an alphanumeric value to a
numerical id and then use that id for matching in drouting (or other tree
indexing modules such as mtree).
Cheers,
Daniel

Hello List,
i use kamailio-5.0.4 and i experiment with the drouting module with
mysql-db.
I try to route with "alphanumeric" stuff - like 'tetris' in
sip://tetris@mytest.example
https://www.kamailio.org/docs/db-tables/kamailio-db-devel.ht
ml#idp31352844
The DB-Field is an 64 string like route-id. In dr_rules.route-id i can
use "named-routes"
if i leave the prefix empty or i fill in only numbers.
With strings i got this error:
ERROR: drouting [dr_load.c:555]: dr_load_routing_info(): failed to add
rule id 4 -> skipping
SQL Result for rule-id 4:
# dr_rules
# ruleid, groupid, prefix, timerec, priority, routeid, gwlist, description
'4', '9000', 'tetris', '', '0', 'tetris',
'4', 'testroute'
Is drouting only for "number-routing"?
