ISDN-Gateway

Um einen echten ISDN-Anschluss an eine UCware anzubinden, wird ein Media-Gateway benötigt, welches die Schnittstelle zwischen ISDN und SIP darstellt. Folgende Gateways stehen zur Auswahl:

• Patton 4131 - Gateway für 2; 4 oder 8 ISDN S0 Ports
• Patton 4970 - Gateway für bis zu 4 ISDN E1 Ports

Mit dem folgenden Befehl kann für einfacheres NAT Traversal die IP-Adresse im Contact- und Via-Header sowie im SDP auf die externe Adresse der Patton gesetzt werden. NAT-Probleme führen häufig zu fehlenden Audio-Strömen in eine oder beide Richtungen.

context sip-gateway GW-SIP

   interface GWIF-SIP

Folgende Liste enthält alle SIP ↔ e.164 default Mappings der Patton-Firmware, welche Hilfreich sein können um Huntgroups und ähnliches richtig zu konfigurieren
