Good day all We have a few of asterisk server running sip and zaptel/voicetronix cards. All the server works 100 for calling in and out of the pstn and internally Some of the server are owned by the same company so I configured IAX so they can call different extensions at different branches Now,how do I configure asterisk so that if someone calls there public ip asterisk will answer as if its coming in from the pstn I.o.w I want to phone a IP instead of a phone number Can this be done? Thanks Altus
