Hi Stefan and Bogdan,

Thanks for all the positive feedback, yes I thougt that 183 response and 404
not found on early announce or bye for announce application in SEMS would
work. But it could also be used for service wide announcements and combined
with callerid patch and database with language option...

Our concept is to make telecom free, so for internal calls, +883, ENUM and
other voip networks there will not be an announcement We know that the promo
announcement must be short. :) There are so many people willing to help out
by donating a server. So we have 0 cost and only pay the actual minutes at
increadible rates. If we could we'd let you dial everywhere in the world for
free.

Just another question out of curiousity, in the OpenSIPS routing script, you
can set sip messages "40X forbidden" etc. Could one also make this "Gandalf
says: 40X forbidden"?
  or would that really screw up any Linksys, Snom, Asterisk or other voip
equipment?

Albert
