Failed deletion of Grandstream GXW4104 Sip Trunks

[jonnyfx]

When I try to delete my 6 analog SIP trunks (for 2 x Grandstream GXW4104 analog devices), I get the following error message.

"Commit failed on transaction Delete TCX.Configuration.Interop.Wexternalline"

Not sure how to proceed to clear these from our system.

I would suggest that a support ticket is created as this require from our Support Team to check further.

Same issue. It's a bug that the delete doesn't work. I'm not prepared to pay to investigate so just put up with 16 unregistered 'SIP Trunks'. But it annoys me.
