SOURCE: how can I install a GXP-2000 IP phone, remote
The exact method really depends on your ip-pbx and whether or not you will have a persistent VPN between the remote site and the main site.
If you have the VPN then the most you would have to do different would likely be to manually set the ip settings for the phone.
If not, then you will likely be dealing with a pretty complex implementation that will require in depth work with the PBX, firewall, DNS, and possibly security certificates.
Some IP-PBX units do decent job of shielding you from the gory details but without more info to go on, i.e. details on the PBX type and whether or not you will be using a VPN, this is about as far as we can go at the moment.
If you need more, please post a follow up with additional information and we'll be glad to continue.

If both phones are showing the same symptoms then it probably means that your DHCP server is down or not configured properly. If the phones are on a separate VLAN and you have recently upgraded or replaced your network switch then it could be misconfigured as well - specifically it may require you to configure a DHCP helper address.
