Hi

ATA 186 with ver 3.02.04(090202A) registered with CUCM 6.1.4.2190-3

Issue we face is, this ATA box automatically unregister from CUCM server.

Once we restart ATA box. It register immdiately. After 1-2 days again it goes into unregistered mode.

ATA is loaded with the latest firmware available in Cisco site.

I have attached ATA screen shot for more information.

Pls. suggest.

Hi Rajesh,

I looked at the screen shots, and the ATA definately has the latest firmware.

How many ATA's are unregistering?

What is the connectivity between the ATA and call manager, you will need to look at the application logs to see with what reason code does the ATA unregisters, check the link below for the reason codes:

If issue is only with one ATA, can we try a factory reset on the ATA, below are the steps:

1.            Unplug the Ethernet cable.

2.            Pick up the telephone handset (please make sure the phone is
plugged in to port 1).

3.            Press the function button on top of the ATA (To access the
Voice Configuration Menu).

4.            Enter 322873738#* (Reset box configuration).

5.            Hang-up.

6.            Wait for approximately 1 minute.

7.            Unplug the ATA power cord.

8.            Reconnect the Ethernet cable.

9.            Reconnect the ATA power cord.

10.          Wait for 2 minutes and the access the ATA via the Web

(http://ATA-IP/dev), or check if you get a dial-tone.
