[cisco-voip] CME 4.1 register SIP phones on different subnet

[tele]

Ok maybe i found the way:

http://www.cisco.com/en/US/products/sw/voicesw/ps4625/products_command_reference_chapter09186a0080611355.html#wp1051341

unfortunaly id network works only on SRST mode :-(

cme-test(config-register-pool)#id network 192.168.2.0 mask /24
Failed: CME mode only accept mac address!

any other ideas?

:tele
