Each instance of the telephony engine is considered a single phone set. SIP uses this name when calling other IP phones. The SIP endpoint on the far end of a call normally displays this name to the user when detecting an incoming call. This name is also used if you allow the telephony engine to register with a SIP proxy server or a registrar server. In the case of SIP proxy and registrar servers, this is the name of your telephony engine in the domain of the SIP proxy or registrar server. The name you assign to the telephony engine can contain any alphanumeric characters, (a-z, A-z or 0-9), and any of the following characters: dash (-), underscore (_), period (.), exclamation point (!), tilde (~) or asterisk (*). Also, the phone name must not contain any "white space" characters.
