I used to have the same problem and I found out it was a 7970 firmware related issue.
I tried several firmwares and finally found out SIP70.8-3-3SR2S is the most stable.

I am hosting the dns zone on the sipX server and have my DC's pointed to it for that particular domain but the actual A record did not exist for some reason so I added it manually and all is fine now. Thanks for the help.

Too short a setting (the default of 5), could be easily interrupted by a slow network, etc. I'm not a cisco fan, and simply use polycom whenever possible, because it doesn't do stuff like this.

I am building a new pbx and I have about 10 phones (7971) registered, after a few days I noticed about 3 phones have lost the registration, not sure why and still investigating. -gabriel On Sat, 2 Jan 2010, Nathan Nieblas wrote: I've just recently deployed sipXecs 4.0.4 to replace an aging trixbox installation. Everything has gone great except we have a couple Cisco 7970's that keep losing their registration after being idle for a period of time. Any ideas on what is causing this? I've dropped their registration timer from 3600 seconds to 600 seconds but that did not help. It also doesn't appear to happen as long as the phone is being used regularly. Our environment also consists of quite a few Polycom Soundpoint 330's that do not have this issue, all phones have been provisioned using sipX generated config files and TFTP.
