Information

SwyxServer Detection via DHCP

SwyxWare supports two mechanisms of distributing the SwyxServer name to SwyxIt! clients (see SwyxWare documentation):

• Vendor specific DCHP option 43 (magic string IPPBXSRV as hex digits, followed by 4 bytes server IP address and 4 bytes fallback server IP address)
• Configure DNS entries "ippbxsrv.yourdomain.com" and "ippbxsrvfallback.yourdomain.com", resolving to the IP addresses of your SwyxServer and fallback server (replace yourdomain.com with your own domain name).

Windows Vista as well as Windows XP SP3 does no longer support vendor specific DHCP option 43. So please use the DNS method for distributing the SwyxServer addresses when you are using Windows Vista or Windows XP SP3.
