[SR-Users] DIALPLAN Module: doubts about regular expression usage

[Stefano Bertuola]

Hi Patrick.

Thanks for your replay.

I also verified an issue with *dialplan.translate* command in *kamcmd*.

Running a live test it is working.

mysql> select * from dialplan;
+----+------+----+----------+--------------+-----------+--------------+----------+-------+
| id | dpid | pr | match_op | match_exp    | match_len | subst_exp    |
repl_exp | attrs |
+----+------+----+----------+--------------+-----------+--------------+----------+-------+
|  1 |    1 |  1 |        1 | ^(\+39)(.*)$ |         0 | ^(\+39)(.*)$ | \2
     | 1     |
+----+------+----+----------+--------------+-----------+--------------+----------+-------+
