I see lots of similar problems with my SPA-3002. Most of the time it is
OK and then it seems to start playing up, both on VOIP and PSTN. The ATA
is so complicated it is always possible to say other setting will fix
the problem. I don't know how many hours I have spent trying to get it
right.

My solution will be to get a Siemens C475IP or maybe the similar SNOM
M3. I'm only holding back while I try and work out what P2P is doing to
mess my router up.
