Configuring the IP Phones
DNS Caching
The IP phones have the ability to cache DNS requests according to RFC1035 and
RFC2181. The phone caches DNS lookups according to the TTL field, so that the
phone only performs another lookup for an address when the TTL expires.
Configuring DHCP
You can enable and disable DHCP using the configuration files, the IP phone UI,
or the Aastra Web UI.
