I have 7 ata186 at customer site. 6 ata with SCCP signaling image and 1 with H323 image. I manually configured 6 SCCP ATA and these ATA are working fine and registering with the callmanager. I also changed the H323 image of single ata with SCCP image and also manualy configured it on ccm but it is not registering with ccm. I can see the sccp image on that particular ata (http://x.x.x.x/dev) and the ata is geting the IP and TFTP IP as well but ccm is not showing it (not found). Need suggestions!!
Save yourself some time and replace the hardware!! I have several ATA 186's myself and one that would get an IP but wouldn't register with Call Manager. After 2 days of troubleshooting (and cursing), I finally pitched it and ordered a new one. I plugged the new one in and it registered immediately as soon as I entered the MAC address. Sometimes they just get hosed!
