i need to convert my 7960 phone from SIP back to call manager



Re: i need to convert my 7960 phone from SIP back to call manage

follow this procedure:

1) move the following file into a temp directory on your CallManager Server.


2) extract the contents of the zipfile into the TFTP directory on your

callmanager. (usually c:\program files\cisco\TFTP) It's the directory with

all the other SEP*.cnf and *.bin files in it. Put these there as well.

3) hard-reboot the SIP phone by physically unplugging it from any power and

unplugging it from the network.

4) ensure that auto-registration is enabled on your CallManager cluster.

5) Plug IP phone back in to the network and make sure that it's in the voice

VLAN and receiving an address and option 150 or option 66 that points it to

the CallManager server. This assumes you're using DHCP to deliver IP

addresses to the phones.

6) if successful, phone will reboot several times - it'll first downgrade to

a MUCH older Skinny Phone load, then update to a more modern Skinny phone

load. When done, the phone will either be auto-registered to the

CallManager, or will be back at the config it had when it was last connected

to CallManager before being converted to a SIP phone.
