jlumby Posted May 8, 2009 Report Share Posted May 8, 2009 I am doing it very successfully. I would say the number one problem is people trying to use junk routers that do not fully know how to statefully packet inspect/translate SIP as it does the NAT for it. I would highly suggest doing your NAT on a Cisco ASA5505 with Sip inspection turned on. I have had wonderfull success with this unit. It is fully featured with all of the DHCP, AND QoS features you would ever want. Quote Link to comment Share on other sites More sharing options...

What features do you have turned on the cisco phone? nat enable 1 and nat address "public ip i'm coming from" ? do you have those turned on or off?
