ATA not registering with CME

mcabral89 · ‎08-12-2015

Hello!

My name is Matt and I am in need of some assistance. I have been asked to expand the existing paging system for a company that I help maintain. Two of the three facilities already have a working paging system. I have been tasked with adding in the third facility with its own extension.

I have configured the equipment identically to the other two working devices within Call Manager Express. I have created the ephone with the correct MAC. I double and triple checked the MAC to make sure I'm not a complete idiot. I have created the ephone-dn assigning the unique extension, and i have linked the ephone/ephone-dn with the correct button.

The ATA is pulling an appropriate IP address and i can ping from CME to the ATA. However, when i type the command "sh ephone ata", I only see the other two existing ATAs. I've restarted the ATA multiple times in an attempt to get it to register. I've looked and compared all my working settings against the settings at the third site and everything is configured exactly the same way. I don't know what else to look for. I know i haven't given a lot of specific information. I just don't know what info I should supply. I will supply any information that I can, when needed.

I am novice in every sense of the word when it comes to CME. I have had to research and just figure out what I've had to do so far. I never managed to get the web interface for my CME to actually load. I've done everything thus far from command-line only. Please be very literal and linear with any suggestions or answers.

Thanks in advance!!

Model is Cisco ATA 186. All three are the same model and are running the same firmware version. How do i collect debug information for you? i've uploaded the current config file. The ATAs are ephone 60-62. The one that is not working is ephone 62. I do realize that the call-forwarding settings are different for that ephone, but call forwarding shouldn't be enabled on any of them. I initially had the call-forwarding settings added, but ended up removing them just to see if it was somehow messing with the device. I never added them back.

I believe i have found the issue. I am unable to change SID0 to a value of 1. It keeps reverting to a value of 0. I have attempted changing the value through both the web interface as well as the IVR. Any ideas?

Hi Mat,

Not worked with CME, but have experience with CUCM. I know the ATAs are very problematic. Have you checked the Cisco website to ensure that the model of ATA and software release is compatible with your version of CME ?

I have confirmed that all my ATAs are using identical firmware versions, and my switches are all configured identically(thought it might be a vlan issue-it wasn't).
