Phone model: 7970G

firmware version:

SCCP70.8-3-3SR2S (success)

SCCP70.8-3-3 (stuck)

if you try to configure the phones manually does it work??

usually configuring IP is not related to firmware but to a DHCP issue. do the switch ports have a valid DHCP scope or free ip addresses??



if this helps, please rate

When I encounted with this issue, I tried to replace another phone set to the same switch port, and it can boot up.

So I wonder it might not the switch or network problem.

Hello Jeff,

Have you ran any debug ip dhcp commands?

This initially sounds like a DHCP or firmware issue.

Can you teach me how to configure the phone "manually"?

for example, how to configure DHCP for a phone?

I wonder if its a licensing thing, have you checked your licenses since you started adding new phones?

I am experiencing the same problem but with different firmware.

Phone 7961

Firmware sccp41.8-3-4sr1s. The phone gets stuck in configuring up after upgrading firmware from sccp41.8-3-2sr1s.

I had to move the phone to a different port and go back to the lower revision. Trying to find out why this is happening

I've had this with a UC520 system as well as a 2800, with different handsets and differing software models.

Believe it or not my issue was dodgy wall sockets and badly made network cables.

After re-terminating the wall sockets and renewing the cables my issue dissapeared.

It looks like some of the sockets were providing power, but not providing adequate network capabilities.
