I have a problem with my VoIP phone - conversations only last for a few minutes before they go dead.
This has happened with 2 different called numbers, so I don't think the problem is at the other end.
I have been using the same hardware and software settings for many months - without any problems until today.
My VoIP Router is a Fritz!Box 7490.
My phone is a Cisco SPA504G.
My VoIP provider is Maxo Telecommunications Pty Ltd.
I have a normal ADSL line - that is not used for any other purpose.
What could be causing this problem?
Are there any logs that would help identify the problem?
