I have a callmanager business edition version 6.1(2). After all the necessary
configuration including license activation and services activation, the phones could not register with the callmanager. I checked the network configuration on the phones; and they have gotten IP address from the dhcp which I configured on the Voice gateway. They also have the ip address of the
callmanager and the voice gateway as their TFTP server and default router respectively.
I could ping the phones from both the router and the switch and I could also ping the router and the switch from the callmanager. But I could not ping the phones from the callmanager.When I checked the version of the callmanager license from the license unit report, I noticed that it is 6.0 while the Callmanger (business Edition)version is 6.1(2). Could this be the reason why the phones cannot register. I need help.
