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!!
