We’ve recently installed & started using an Asterisk system along with elastix. We’ve set up an outbound route that needs to display an 866 number. Originally, our provider (Cbeyond) said it would be no problem for them to set that up. We would use a number that they’d given us & they would set up the outbound ID to show the 866 number. Now they say they can’t because the outbound route has to have a real number that they’ve given us. When they try to set the outbound ID to the 866 number on there side the line no longer works for outbound calls. They told me I have to set the outbound ID with a “Diversion Header”. I’ve done some research but haven’t found anything that gives me clarity on where I need to go to edit or effect the Diversion Header.
Does anybody have any ideas or understanding of what they’re asking me to do? Any thoughts or help would be greatly appreciated.
