i have ATA 187 registered in its two ports with CUCM 8.0(3) and i have VG 2921 with SRST version 8.1 i configured a voice register pool for each port as follows:
voice register pool 1
id mac 0012.7F3B.9025
number 1 2800
voice register pool 2
id mac 127F.3B90.2501
number 1 2801
the above MAC is just an example. if ATA MAC is 0012.7F3B.9025 then this will be for port 1 which is registering fine and 127F.3B90.2501 will be for the second port as the way it is registering with CUCM server.
my issue is that the second port in ATA is not registering in the SRST gateway. Iam not sure if something is missing on my configuration.
when the ATA is in SRST mode, i checked the SIP statistics with "show voice register pool 1" and "show voice register pool 2"
for pool 1 i see the sip requests and registration while on the pool 2 there is nothing (not even a request). I am not sure if i configured the second port correctly since i did not see any cisco document stating how to configure that on the gateway.
i will try to check with 'debug ccsip mess'. it is stated in cisco that ATA 187 is not supported officialy in CME until summer 2011 but nothing mentioned about SRST mode.
