Adding SIP trunk get DB error that duplicate key exists

I’m trying to add a SIP trunk. . When I attempt to add any new SIP trunk (with any trunk name, in this case testtrunk44), I get this. Any thoughts on how I can get rid of this record in the DB?

FATAL ERROR
DB Error: already exists

INSERT INTO sip (id, keyword, data, flags) values (‘tr-peer-4’,?,?,‘0’)
