Leitfaden für industrielle SIP-Telefonzeiteinstellungen (einschließlich Netzwerkzeitsynchronisation)

Einführung

Überblick

Diese Anleitung erklärt, wie Sie die auf dem Telefon angezeigte Uhrzeit synchronisieren.

Geeignete Modelle

Alle unsere Telefonmodelle unterstützen diese Funktion (in diesem Artikel wird das X5U als Beispiel verwendet).

Voraussetzungen

① Ein Telefon, das an den Switch angeschlossen ist und eine IP-Adresse erhalten kann.
② Ein Computer für die Konfiguration, der mit demselben Switch verbunden ist wie das Telefon, um die Netzwerkkommunikation zwischen Computer und Telefon sicherzustellen.

Konfigurationsschritte

Methode 1: Uhrzeit vom SIP-Server synchronisieren

Tippen Sie auf dem LCD-Bildschirm des Telefons auf “Menü” — “Status”, um die IP-Adresse des Telefons zu überprüfen.

Melden Sie sich an der Weboberfläche des Telefons an, indem Sie einen Browser auf dem Computer öffnen und die IP-Adresse des Telefons in die Adressleiste eingeben.
Weboberfläche
Nachdem Sie sich an der Weboberfläche angemeldet haben, gehen Sie zu “Leitung” - “SIP” - “Erweiterte Einstellungen” und aktivieren Sie “Telefonzeit synchronisieren”.
Telefonzeit synchronisieren
Wenn die Uhrzeit über die SIP-Registrierung synchronisiert wird, verwendet das Telefon das Datum-Feld in der 200 OK-Antwort des Servers als Zeitreferenz und passt es dann entsprechend der konfigurierten Zeitzone des Telefons für die Anzeige an. Wenn die SIP-Zeitsynchronisierung aktiviert ist, werden die SNTP- und DHCP-Zeitsynchronisierung automatisch deaktiviert. Diese Methode erfordert, dass der SIP-Server ein Datum-Feld in die 200 OK-Antwort aufnimmt.

Methode 2: Netzwerkzeit synchronisieren

Melden Sie sich an der Weboberfläche des Telefons an, gehen Sie dann zu “Telefoneinstellungen” - “Zeit/Datum” und konfigurieren Sie die Einstellungen wie unten in Abbildung 1 gezeigt.
Die Verwendung von SNTP zur Zeitsynchronisierung bedeutet die Konfiguration der “Primären/Sekundären Zeitserver-Adressen”. Diese können als IP-Adresse oder Domänenname festgelegt werden. Nach dem Start fragt das Telefon den primären Server nach der aktuellen Uhrzeit ab. Wenn der primäre Server nicht antwortet, wechselt es automatisch zum sekundären Server. Während des Betriebs aktualisiert das Telefon die Uhrzeit regelmäßig. Diese Methode erfordert, dass die SNTP-Serveradresse vorkonfiguriert ist.

Methode 3: Uhrzeit über DHCP synchronisieren

Melden Sie sich an der Weboberfläche des Telefons an, gehen Sie dann zu “Telefoneinstellungen” - “Zeit/Datum” und konfigurieren Sie die Einstellungen wie unten in Abbildung 2 gezeigt.
Um diese Methode zu verwenden, muss sowohl “SNTP-Zeitsynchronisierung verwenden” aktiviert sein als auch der Netzwerkmodus auf DHCP eingestellt sein. In diesem Modus erhält das Telefon beim Start seine IP-Adresse über DHCP. Wenn es die ACK-Antwort des Servers erhält, liest es die SNTP-Serveradresse aus Option 42 und schreibt sie in die Felder “Primäre/Sekundäre Zeitserver-Adressen”, dann synchronisiert es die Uhrzeit über SNTP. Diese Methode erfordert, dass der DHCP-Server Option 42 unterstützt.
