We are having the said issue with all the branches after we have migrated the cucm 6.1 to 8.6, wireless phones register to VGW with SRST mode about 2 times a day, we have to manual kill it on the WLC in order to force them to register on the cucm8.6, it is really a pain, has someone ever encourred such issue before? everything was alright before the migration, now only wireless phones having this issue
Action taken
rebooted wlc and AP but changes
please advice
thanks very much
