In my case, I don't have to set firewall on IP01, Stun in Linksys IP phone is not needed.  All firewall is responsible by my Router and that makes my life easier.

To resolve the line dropped problem, I suggest rebooting IP01 every mid-night and it might help.

如果IP01 及 AT610 在同一LAN之下，IP01 已用了 abc.com 作為DOMAIN NAME，那麼，AT610就不建議設立DDNS了，只需在Router 作適當routing 便可以，否則有時router 會傻了，不知派往那一部機才對的。

To my knowledge, some devices are not clever enough to get the proper destination address if ALL of them are given DDNS in the SAME LAN.  It is not necessary, in fact.

In my case, DDNS should be deployed in Router in the first place.  To meet the Asterisk Server requirement, I also put it in the sip.conf as well.  All other ATA/IP phones use only internal IP address (static one should be better).   You may also find from ATA 3102/3000 or Cisco IP Phone SPA942, DDNS is optional only.

I don't have AT610 and hence cannot comment its capabilities.  Are you using Google DNS 8.8.8.8 and 8.8.4.4 in your router?  If not, you may give it a try.
