Hi Nicolas, I had this problem too on some pods, where only one of the HQ phones want to register, same for site B, dhcp addressing is working but no registration occurs. Because I had no physical access on the phones to check what the display is showing ( I guess something like registration rejected), I tried several things to avoid this issue for the next session.
In most cases it has worked when I used completly different dhcp ranges in the subnet, e.g 200.70 - 200.80. When 7960s had problems to register it helps to configure them manually in the cucm. Afterwards they are shown as registered. In some circumstances it only had solved the issue when I configured a dhcp pool on the router (for siteB probs) or on the HQ Sw for the HQ phones.
