The approach that I have taken is... 1 - at each place that I have asterisk, register the users full number with e164.org (or equivalent) 2 - Make sure I do e.164 lookups as part of the normal process of placing a call... 3 - If a call comes in via VoIP - alter its CLID so it looks the same as an incoming telco call - which makes identifying and returning the call simple. Effectively - I use the dialling plan from Telco. Each site retains its 'historical' number - which is probably the same as everyone has in their Rolodex/Diary/PDA (etc) - so there is no customer learning - or dialing funny access codes - etc.... If the call does not get through - my system simply uses the Telco line - as in the old way. If your client calls anyone else who implements the same rules - they'll get through on VoIP too... and if I take a phone book, look up your customer and call the number given - I'll use VoIP too... The only time that I do not do any number lookups is to 911 or operator specific numbers... which in South Africa tends to be '10XXX' format. This works fine for any Asterisk installation that has both traditional (= fixed connection to telco) and VoIP circuits. -- . . ___. .__ Posix Systems - Sth Africa. e.164 VOIP ready /| /| / /__ [EMAIL PROTECTED] - Mark J Elkins, Cisco CCIE / |/ |ARK \_/ /__ LKINS Tel: +27 12 807 0590 Cell: +27 82 601 0496 _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
