Operational Parameters Chapter 5 Parameters and Defaults Table 5-6 OpFlags Parameter Operational Features to Turn On or Off (continued) Bit Number Definition 11 If Bit 11=0, the Cisco ATA requests the device hostname from the DHCP server. If Bit 11=1, the Cisco ATA uses the device hostname that is specified in DHCP option 12. Default: 0 12 Reserved. 13 DNS Servers For Name Resolution If Bit 13=0 (default), use statically configured DNS IP addresses, if available, for name resolution. If statically configured DNS servers are not available, use DHCP-provided DNS IP addresses for name resolution. If Bit 13=1, use both statically configured DNS IP addresses and as many as two DHCP-provided DNS IP addresses. Therefore, the Cisco ATA can query as many as four DNS IP addresses in one DNS query. For more information about statically configured DNS IP addresses, see the "DNS1IP" section on page 5-11 section and the "DNS2IP" section on page 5-12 section. Default: 0 14 DNS Servers For Name Resolution 2 If Bit 14=0 (default), use statically configured DNS IP addresses (DNS1IP and DNS2IP), if available, for name resolution; otherwise, use DHCP-provided DNS IP addresses. If Bit 14=1, use both statically configured (DNS1IP and DNS2IP) and DHCP-provided DNS IP addresses (maximum of two) for name resolution. 15 16-27 28-31 Note This configuration bit gives precedence to statically provided DNS IP addresses over DHCP-provided DNS IP addresses. This bit also overrides the value of OpFlags parameter bit 13. Disable UDP Checksum Generation If Bit 13=0, generate UDP checksum in outgoing UDP packets. If Bit 13=1, disable generation of of UDP checksum in outgoing UDP packets. Default: 0 Reserved. To configure the Cisco ATA to prompt the user for the UIPassword when the user attempts to perform a factory reset or upgrade using the voice configuration menu, configure bits 28 to 31 with the value of 6. Any other value for these bits means that the Cisco ATA will not prompt the user for the UIPassword in these cases. TimeZone Description This parameter is the timezone offset (in hours) from Greenwich Mean Time (GMT) for time-stamping incoming calls with local time (to use for Caller ID display, for example). See the "Additional Description" heading later in the description of this parameter for selecting time offsets for timezones that have 30-minute-factor or 45-minute-factor offset from GMT. Local time is generated by the following formula: • Local Time=GMT + TimeZone, if TimeZone 12 5-36 Cisco ATA 186 and Cisco ATA 188 Analog Telephone Adaptor Administrator's Guide for H.323 (version 3.0) OL-4804-01
