The Linksys phones are based on the Sipura technology. I happen to have a SPA2000 ATA, so I'm guessing the interface will be similar.
Access the web interface to the phone.
Log in as an admin level account, not a user level account.
Click on Ext 1 at the top.
Set the following:
- Code: Select all
Line Enable: Yes
NAT Mapping: No
NAT keepalive: No
SIP Port: 5060
Proxy: <your *now IP or DNS name>
Register: Yes
Make call: No
Register Expires: 3600
Ans Call: No
Display Name: <your name>
User ID: <* configured user account>
Password: <* configured password>
Use Auth ID: No
Click the save button at the bottom, the phone will probably reboot.
You obviously need to configure a user/extension in *now first, such as 6000, and assign it a password. The password can be alpha-numeric, but those can be hard to enter for voicemail access.
Alter NAT as applicable. Set the outbound proxy to the same IP as the proxy if you want to route all traffic through *.
