Trying to add a DID that I deleted back into the SIP Trunk

[Dewayne Orender]

I was having issues with duplicate EXT but with different MAC addresses and only showing up as 3CX APP numbers. I deleted both duplicates from the EXT list and somehow it deleted the number from the DIDs. I have tried to readd the DID and received an Error the DID is already in use. I have tried to save and reenter the SIP trunk DID list to no avail. Anything would help!
