I know that openSER is only "transaction stateful", not "call
stateful" and i thought the dialog-module works only global.
But parsing the output for "From" could be a solution. That`s a good
idea.
I`ll try that tonight.

Perhaps i could use Asterisk with mySQL-views to the subscriber-table
of openSER and
create "virtual" peers in asterisk with a "call-limit" from the
subscriber-table.

Kind regards,

Sebastian.
