Function errors showing in log

Fresh install of Distro FreePBX-64bit-10.13.66 on ESXi 6.0
SIP phones on 5061. Inbound and outbound all work fine.

Everything is functioning but every call extensions receive, I get the errors pasted below.
Interesting one is “Can’t find trailing parenthesis for function ‘DB(DEVICE/4495/dial’?
(4495 is my extension)

The errors are not appearing to affect anything, but its definitely polluting the log.

Anyone have any thoughts what might be?

Please check the sip you are using.

Standard SIP on port 5061. Everything registers just fine, just seeing these entries in the log every time a call is made.

And today, they appear to have miraculously stopped.
