We have an UC500 running and want a Linksys Sip phone to connect to it. The UC500 uses the CME IOS.
The phone registers itself correctly. I am able to call the extension. But when i pickup to answer, or to place an outbound call, i'll get an busy tone.
I've made the following additions to the UC500:
Voice register global
authenticate realm test.local
Voice register dn 14
voice register pool 14
id mac xxxx.xxxx.xxxx
number 1 dn 14
Username xxxxx password xxxxx
I hope somebody can point me in the right direction.
