3web/Distributel VOIP: Call cannot be completed as dialed
This is a much delayed updated from this thread: »3web/Distributel VOIP Behind Router: So close, help please!.
For the most part, the VOIP has been working successfully. However, over the past few days, I have repeatedly come across an odd behaviour. I recently made a few calls, and three-quarters of them give me an error response: "This call cannot be completed as dialed". However, if I make the call to the same number from my cellphone, it works perfectly.
Does anyone have any ideas about why my VOIP is being so selective about who I am able to call?! This is pretty frustrating (although I am glad I have a cellphone to use as backup!)
Any advice would be appreciated!
