A R&S®NC VoIP router is switched between the ISDN outside line and the existing ISDN PBX. In the PBX, automatic outside line access is enabled, the call router settings for the R&S®NC VoIP router decide whether or not a "0" must be dialed for outside line access for the connected ISDN and SIP subscribers.
