Very weird connection problem!

Running a 2nd adapter along side it may be related. Do you know if both adapters are using the same ports?

Since only port 1 is having issues and port 2 is fine, that pretty much rules out it being a connection issue to us since both would have issues.

Is your unlocked adapter using the same port as port 1 of the VOIPo adapter?

What are the ports VOIPo uses?

I think Tim is only referring to the main port.
On VOIPo, usually 5060.

The second line is usually on 5061

I often wonder why companies use the default settings? Perhaps defaults play nicer in most cases?

At least the whole service is not out since line-2 keeps working!
