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

[Daniel-Constantin Mierla]

Hello,

this might be due to automatic translation of kamcmd for its parameters
that look like numbers, can you try with:

kamcmd dialplan.translate 1 s:+39123456


If still fails, send here the log messages with debug=3 when running the
rpc command.

Cheers,
Daniel
