There used to be a defect where ATAs with only one line
configured/registered would deregister due to the second line constantly
attempting to download a configuration. I am not sure if it only impacted
the 18X or not though . . . I’ll try to find an article.

I've used the ATA190 and it's family of 18X pretty often. In the case of the
SIP devices like the 190 or 187 I have always been able to use the default
SIP Profile settings; of course I'm generally dealing with vanilla networks
and CCM's built very closely to the SRND.

Here is where I would start (if you haven't already):

What do you have the device security mode set to? If you have it set to
Authenticated or Encrypted but it has not received a CTL file, the phone
will attempt registration up to four times to make a secure connection.

Are the MAC addresses for Phone 1 and Phone 2 correct (Phone 2 will usually
loose the first two characters and append a 01 at the end of the device
name). If you support auto registration, remove the devices and let them
auto register and see if they stabilize.

Any layer 1/2 issues (change out the patch cable, check the connection into
the switchport ... etc)? Do you see any interface drops on the switchport?
Is the switchport full duplex 10/100 or 10/1000? Have you shut/no shut the
port just to see if clearing the port helps?

Go through the IVR menu on the ATA itself and verify that it reports all the
same settings that you CCM device configs show.

Hi Guys,

   ATA190 FW version 1.1.2.(005) with CUCM 10.5.2.10000-5, de-register
randomly, and need to reboot the device to re-register again on the CUCM.

 

Anyone as the same issue? Do you use a special SIP Device profile changing
some timings, or you are using standard SIP Device Profile?

 

Thank you all

 

Regards

 

 

Alessandro Bertacco
