Some 7940 Phones will not downgrade to earlier phone load
We have some users in a Device Pool whose 7940 phones have vers 7.23 (sccp) phone load while the rest of the organization is at 7.22. We have Callmanger 4.13sr2 running. We have an issue with 7.23 and Berbee paging not supporting that version.
Problem: Cannot get certain phones to download the 7.22 load. Get a brief file download error message on phone screen after erasing configuration of phone and rebooting.
The TFTP server ip address is correct and same as other phones as well accessible. Other phones off same switch and of the same model downgraded. I have moved a few of the phones from that site, and placed them on the same switch as the tftp server(publisher), and the downgrade performed normally on bootup.
I have about 30 phones with this issue. Anybody have a similar experience or solution?
