CUCM 6.1.4 Slow firmware upgrade

Hello All,

I am upgrading 7962 IP Phone, and firmware reaches phone at about 64Kb every 10 seconds. Network is no the issue as I have tested it. Do you think is there any parameter in CUCM that produces this behaviour?

Many thanks.

Re: CUCM 6.1.4 Slow firmware upgrade

only 1 phone?

which tests u did to confirm is not a network problem?

CUCM TFTP and phone are across the WAN?

Any firewall in the middle?

if u connect phone to same LAN as CUCM TFTP any change?

Let us know more details about the topology.

Finally, the problem was the network, but not the download bandwith to the phone. Was the upload bandwith from phone to call manager.

Many thanks.
