Hi!
In theory it should not appear like that but both WebRTC and Zulu create additional extensions for each extension. There additional extension have prefixes such as 90, 99 and 9999.
Re:
Now if there was a problem with those duplicate (of sorts) extensions I would expect them to be shown with their prefix but I can’t think of anything else right now…
Is it possible you had this activated on FreePBX 13 and not on FreePBX 14?
By the way, what are we talking about? The FreePBX distro upgrade with the distro upgrade “script” or a non-distro system upgrade with the PBX upgrader module?
If this is the result of the distro upgrade “script” please don’t forget to create a ticket and upload the logs as instructed in the troubleshooting section.
Good luck and have a nice day!
Nick
