Hi Tahir,

This is what the minimum configuration looks like:

voice service voip


registrar server

voice register global

mode cme

source-address port 5060

max-dn X

max-pool X

voice register dn 1

number 1000

voice register pool 1


type ! If it's 3rd party, omit this

number 1 dn 1

username X password X ! Required if IP phone's address is on different subnet than SIP CME source address

You can also look at the documentation here:

You need to make sure the x-lite client is actually adding an Authentication Header to the REGISTER message it sends. This looks like it would be an endpoint configuration issue.

You should see something like this:

-> REGISTER ( no authentication)

M- 401 Unauthorized

-> REGISTER (authentication)

<- 200 OK

You can try taking the 'authenticate register' message out of your voice register global configuration as well.

There also is not a DN defined on the phone. You probably want to add 'number 1 dn 1' to your voice register pool configuration.
