Question about Polycom SoundPoint IP 501 IP Phone
I get the message 'URL call is disabled' on the phone I just connected. The phone shows the phone number and goes through the set-up, but doesn't have a dial tone.
This in it's most basic description means that the phone is unable to register with the SIP server, most likely for lack of internet connectivity or a firewall blocking the packets.
If you've verified connectivity and opened the proper ports and the phone fails to initialize and still getting “URL Call Disabled” or all of the above parameters are correct, update the firmware for the router. This can usually be done within the router configuration. Then reboot in order, the cable modem or DSL, the router or switch, then the phone. This may solve the problem.
If still having the same issue, confirm in the router configuration for settings such as SIP proxy, gateway, or application layer or any configuration setting for SIP or VOIP. If any of these do exist, make sure they are turned off as these may only confuse or adversely affect many implementations.

If you are getting the error message URL dialing disabled, this means that the feature in the config file is disabled and the Polycom phone is not registered against any of the line's configured registration servers.
