Hello Daniel,

indeed dialplan could solve this. But i dont follow that because i dont want to manipulate the $rU part.

if you do not set subst_exp and repl_exp, then no change is done.

To make that feature more visible, the upcoming 5.1 has a dedicated function just to do the match:

Cheers, Daniel

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.html#idp31352844
    <https://www.kamailio.org/docs/db-tables/kamailio-db-devel.html#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"?
