Hi, all We're using Asterisk CVS 3-19-04 with four polycom IP600s. The work very well and we're quite happy with them. They register fine and all four are able to place and receive calls, BUT two of them are behind NAT routers and when they place a call on hold, the call is dropped within 5 seconds. I couldn't find any relevant items in the archive search using terms like SIP, NAT and HOLD. The server has a public static IP, two phones have public static IPs and the two with the hold problem have dynamic NAT'ed IPs. Not sure what other info might be helpful. Any pointers in the right direction would be appreciated. -russ

There's a brief section about it in the Polycom manual. And that's the limit of my knowledge.... Carey
