optiPoint 410/420 V5.1 information

Information to V5.1 of the optiPoint 410/420 CorNet-IP (HFA) phone family.

General Info for all Releases
See section 4.4.5 Reacquisition and expiration "In both RENEWING and REBINDING states, if the client receives no response to its DHCPREQUEST message, the client SHOULD wait one-half of the remaining time until T2 (in RENEWING state) and one-half of the remaining lease time (in REBINDING state), down to a minimum of 60 seconds, before retransmitting the DHCPREQUEST message."
 * Payload Security is only possible with the optiPoint 410/420 eco+/std/adv
 * G.722 CoDec is used with DMC (Direct Media Connection) between two optiPoint 4X0 IP phones only (DMC feature must be activated).
 * A call via Gateway never uses G.722.
 * If “High Quality pref.” is entered, G.722 calls to other OP4X0 or OpenStage HFA are possible, but only G.711 calls to other phones. Because of this the users get a different impression of quality.
 * It is highly recommended to deactivate both VAD (Voice Activity Detection) and Silence Suppression features.
 * To upgrade via NetBoot the Key 3 have to be pressed while powering up the phone until the phone starts to load the image.
 * Netboot Upgrade via Remote is only possible with V5 R1.33.0 or later.
 * DHCP Leasetime: The recommended minimum leasetime is 8min as the RFC2131 is quite unclear about how long a leasetime should be as a minimum.

Since Release V5 R1.34.0 or later
