I am having ATA 188 trying to register with Call Manager version 4.2(3). The hardware/firmware version of this device is as follows:
Version: v3.1.0 atasip (Build 040211A)
DHCP Assigned: IP[10.230.204.7] Subnet[255.255.255.128] Route[10.230.204.1]
HardwareVersion: 0x0010 0x0000
ATA is taking the IP address and the TFTP address, and I have added this box as an ATA 186. But it not registering, and I am not able to view the ATA IP address in Call Manager. ie Either ATA is not able to contact with the Call Manager ot Call Manager is not accepting requests from this ATA.
From the version, we can see this is SIP base version of ATA. Is it possible to register this with Call Manager?
If not what all upgrades need to be done and in what method to register the same?
