Voip Hookup

Either will work. If you connect it behind your home router, you may find that the service works better if you forward certain ports to the Voipo ATA. However, many find that port forwarding is not necessary.

Why does this vary?

Why does this vary?

The need for port forwarding varies with home router model (including the version of firmware running).

yes, but I'm a geek and wonder why some work without explicit port-forwarding and others do not.

Understandable, but I don't have a more satisfying answer. I'm sure it depends on how the firmware in the various routers filters incoming packets, but detail beyond that level is more than I'd know...

My service was working fine for about a year with no forwarding.
Last week all calls suddenly went to voicemail.
Support suggested the usual ports to fix the issue.
I suspect changes with all the network upgrades etc. was the culprit.
