I need to get remote phones registered to a Call Manager over the Internet w/o using VPN. Will it work if the private DHCP address the phones get contains the public address of the tftp server? The remote phones will be on a network in building A going over the public Internet to HQ. The remote phones wil still need to be able to call each other using the extensions and then the gateway to the PSTN will also be at HQ. I think this should be doable correct?
I will also need to do the same thing with some VG248s at the remote sites.
I know I can get this done using VPN but VPN adds additional packet overhead and drives the per call bandwidth requirements through the roof for what should be a simple G.729 call.
Thanks to anyone who answers!!
