Hi, I am having a strange problem with the BLF on a hosted sytem. The phones (Grandstream GXP 2000) work fine internally (LAN) or when Natted (WAN) but from this particular location none of the 3 phones display the BLF (everything else is works fine even the DSS buttons).
I'm thinking it has something to do with the router but does anyone have any ideas on what the problem is ? -- Henry Coleman
