I have installed freepbx 15 with asterisk 18 and I noticed unexpected behavior when adding new extension.
When I add new chan_sip extension and want to add its DID via (Add SIP Extension - Advanced - Add Inbound DID) after Submit it automatically converts the chan_sip extension to virtual extension.
I was expecting that the new chan_sip extension will be added and its Inbound DID will be configured (it worked on version 11).
Is this a bug or a feature ?
Thank you for your answer.
