I need number portability on Asterix

we will attach a pstn line to PBX thru a digium card, and want to travel this number with us thru IP anywhere we go , we will have a IP phone attached at the receiving end

groovy, asterisk can easily handle that application.


IF we have a pstn number in PBX attached with a digium cards and then we send some calls to local numbers … can we block the caller line identification of the outgoing call from pstn… thru any feature of PBX>.?
say i have a pstn 500001 attached to PBX …now when I will dial from PBX this number will be displayed to cell phone i am calling …I want to block this ID or at best distort it … so that .reciever gets 12233 instead of 500001
