Hi Tahir,

This is what the minimum configuration looks like:

voice service voip

sip

registrar server

voice register global

mode cme

source-address 1.1.1.1 port 5060

max-dn X

max-pool X

voice register dn 1

number 1000

voice register pool 1

id mac XXXX.XXXX.XXXX

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:

Hi Nick

Thank you for response,I tried this configuration with x-lite softphone I m getting authentication problem i attached my config with debuging on kindly check it and suggest what i can do

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.

hth,

nick
