I patched my Callmanager this weekend (loaded 4.1(3) sr4d and devpack 36). Since then, my application log on my publisher has been filling up with Transient connection attempt errors in the Application log. It appears to be primarily ATA 186 devices AND mostly the second configured line (where the MAC ends in 01). Any ideas? I have reset the ATA's to no avail.
This error message in CCM is typically caused by ATAs second line not being registered. The workaround is to add the scond line:
...or disable the second line so that registration is not attempted.
