SIP Registration section

The entry fields for a SIP registration are:

• Name: Descriptive name for this registration.
• Disable: A switch to temporarily disable this interface without deleting the configuration.
• Server Address (primary): The optional IP address of the SIP provider to where the SIP messages (REGISTER,INVITE,etc.) are to be sent. Only necessary if either the IP address cannot be obtained from the SIP URI's domain or a proxy server is to be used.
• Server Address (secondary): Backup IP address used if the SIP server on the primary IP address does not answer anymore.
• ID: Here you enter the user ID followed by the SIP provider domain name (for example, 8111111e0@sipgate.de).
• STUN Server: The STUN server name or IP address must be configured if this device has no public IP address while the SIP server is accessible under a public IP address. The value is given by the SIP provider or administrator (for example, stun.xten.com or 64.69.76.23). You can choose any STUN server; it does not necessarily have to correspond to the one of the SIP provider.
• Display Name: The name you enter here, which corresponds to the part in front of the @ of the URI, is required for the registration if the number (Account) was not specified (for example, 8111111e0).
• Account: Likewise in this protocol, a call number is required for the registration, which corresponds to the part in front of the @ of the URI (for example, 8111111e0).
• Password / Retype: The password (Password) of the SIP Account must be specified and confirmed (Retype).
• Supplementary Services (with Feature Codes): See entry fields for an H.323 registration.
• Dynamic Group: See entry fields for an H.323 registration.
• Direct Dial: See entry fields for an H.323 registration.
• Locked White List: See entry fields for an H.323 registration.
