The Senao should use whatever RTP port(s) you tell it to. For example
I've told my Asterisk box to use 50000-60000. I made a few test calls [to
landline, mobile, freephone and 10000] and I found that the port at my
end was always 50000-57000 [as expected], and the port at Sipgate's end
was 10000-12000.

I spotted this in the manual:

"Note 2: Please don’t use the following subnets on the SI-7800H-
192.168.1.x and 192.168.99.x."

which is one of the oddest things I've ever seen in a manual for a
handset. You're not on 192.168.1.* are you?

You could cheat and forward everything to the Senao just for testing
purposes and see if that makes a difference.

I would break out the packet sniffer and see exactly what it's doing.
OTOH, if you're still inside the 14 days, send it back and get something
else.
