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

[Stefano Bertuola]

Hi Daniel.

Thanks for your suggestion. It worked:

kamcmd> dialplan.dump 2
{
        DPID: 2
        ENTRIES: {
                ENTRY: {
                        PRIO: 1
                        MATCHOP: 1
                        MATCHEXP: ^\+39.....
                        MATCHLEN: 0
                        SUBSTEXP: ^\+(.*)$
                        REPLEXP: \1
                        ATTRS: 1
                }
        }
}
kamcmd> dialplan.translate 2 s:+3912345
{
        Output: 6212345
        Attributes: 1
}
kamcmd> dialplan.translate 2 '+3912345'
error: 500 - No translation
kamcmd> dialplan.translate 2 "+3912345"
error: 500 - No translation


Instead, with single or double quotes, it doesn't.
