[cisco-voip] ATA problem in CUCM 7.1(3) !!!

[Jordi Solá Giralt]

Hi,

I had the same issue with a cluster in version 6.1.4, when trying to 
upgrade ATA's to the last firmware version, and I solved it by creating 
and assigning a CallManager Group with only two CallManagers (instead of 
three, as usual if you have a cluster with more than two servers) to the 
ATA devices. In this case the file size is lower than 4k and the bug 
doesn't appears... After the upgrade, now ATA's support config files 
greater than 4 k, so you can re-assign CallManager Groups.

I hope this helps,

Regards,

hi to all..
 
it seems that after cluster upgrade form 4.2(3) to 7.1(3) ATA 186 want 
upgrade it?s firmware from 3.2.3 sccp to 3.24 sccp which is the default 
one in CUCM 7.1(3)..
ATA also want register to primarly confgiured CUCM ( and it keeps it?s 
last known config )..so, it is rather non-usable..
ATA isn?t newly added, it was already configured in 4.2(3) CUCM, so it 
exists in DB..so, there is no auto-reg problem..
 
so, after reading some of the threads and bugs description for CSCsd44357 
and CSCsr45184 i did manage to ?cut? some neccessary info in xml file ( 
ataMACADDRESS.cnf.xml ) and manage to make ATA pickup that config and load 
new firmware ( 3.2.4 ) using TFTP server on y PC..
i think ryann wrote something about it..
 
but, for cluster with 200 ATA devices it is going to be real problem..
 
so, if we?re hitting that 4k bug, or maybe some other bug..
 
is there any ?nicer? solutions for this huge problem..
 
we can upgrade firmware on existing CUCM 4.2(3) and moved them after that 
to 7.1(3) with the same firmware, but isn?t that the same thing, if there 
is a bug in ATA?s 3.2.3 code..
 
this makes sense only if we?re having in mind that ATA speicific config 
file and XMLdefault.cnf.xml are smaller size in CUCM 4.x , beacuse CUCM 
7.X does add some newer feature and info overhead..
 
 
thanx..
 
 
regards..
