Hey there,
At home I have Netgear ADSL router (1 x ADSL, 4 x eth) and have not had
any problems with NAT devices dropping off. Mainly use Zyxel Wireless
2000 handsets.

Does anyone know and use a consumer router which works
with NAT ping?
I did some research recently and can't find any. Basically if a phone
is
behind NAT, we need to keep the NAT binding in the
router active even
if
there is no activity from the phone. NAT ping from ser
(either
rtpproxy or
mediaproxy) tries to ping the phone with an empty SIP
packet. However
this
inbound UDP packet can't always keep the NAT
binding active because
some NAT
firewalls ONLY refresh the timer based on outbound
packets. So the
result is
that the binding expires after a certain time even if
NAT ping is
enabled.
For example, Dlink falls in this category. It appears the timeout is 3
minutes and NAT ping won't make it active.
If anyone has a good experience with any consumer router, can you
please let
share with us?
Use an UA that supports it (Sipura or Cisco for example).
