Hi Team
First I will explain the scenario. IP phones and DHCP server are at one location and the call manager 5.0 is at the other. Call Manager acts as the TFTP server. The phones take the correct IP addresses for dhcp, tftp, call manager and also vlan. But its not registering. Its shows the message Registering on the phone display. I checked the Call Manager & TFTP services, its all active. Recently a new network link was established and network was down for some days. Now it is all fixed and I can ping. During that network establishment the subscriber went down and the phone has to register on Publisher. Its taking the Publisher address but not registering. It has firewall in between. Ports are all open too.. But still its not working out. Please Help.
