Hello,
I also thought about echo because the Zoiper softphone is used with a
headset. But that didn't explain why the echo also appeared on the
analogue phone + gateway.
I have the same Grandstream GXW 4008 gateway with 5 analoge phones
attached in another environment and there, there are no echo-problems.
Can't say the analogue phones that are being used there are top of the
bill, rather cheap stuff actually.
When calling through the analogue phone line, there is no echo (and it
seems therefore that the analogue phones that are being used meet the
quality standards).
The only network-element that is different in the 2 environments is the
router...

Echo cannot be caused by a router.
The zoipher softphone is probably being used with a headset and I
suspect the microphone is picking up the sounds from the earphones
resulting in echo. Try turning down the earphone volume to see if this
helps. If it does invest in some better headphone preferably ones where
the microphone has built in background noise cancelation.
For the analogue phone it could be a similar issue. Some phones are
better than others. Cant you use a proper SIP phone? They work so much
better.
