ATA 187

[Jaime Garcia]

How do I factory reset a ATA 187?  I have manually added it to CUCM and it comes up as Unknown.  What is the deal with these things.  This is the third client that I have worked for that has issues with ATA devices... Never with the 186 models. 

Thanks,

Jaime

Thanks George - I was able to reset the ATA 187 to factorty using your instructions.

The ATA is still coming up as UKnown in CUCM.  I have ATA 186 that are registered but cant get the 187s. 

Any suggestions?

Thanks,

Jaime

Hi Jamie, Assuming you have covered the base configuration, I would try to hard code the TFTP addresses of CM from the ATAs web page.

George - thanks for you help.  After doing another factory reset, and deleting from CUCM and recreating, the ATA registered.  I hate things things.  Hopefully the 188s work better.

Thanks!
