Having issues with 7970 and 7945 color IP phones.
Last week I found that 7970 phones were taking long time to re-register (more than 10 minutes) when I restarted them from CUCM 4.1 (even longer when I reset the phone). No issues when I tested with a 7940. (Restart few seconds, reset few minutes).
Today for a different customer I had the same issue - this time with 7945 IP phones and CUCM 6.1.
Is there something that I may be doing wrong? I can't find anything on CCO.
