Parameter Data Precedence

Parameter Data Precedence

If a given parameter is administered in multiple places, the last server to provide the parameter has precedence. The precedence, from lowest to highest, is:

●LLDP

●manual administration, with the two exceptions described for the system parameter STATIC on page 109.

●DHCP,

●TFTP/HTTP,

●the call server (meaning the Avaya Media Server for H.323, and the Registration Server for SIP), and finally,

●FTP backup files (if administered and if permitted).

Settings the IP telephone receives from backup files or the media server overwrite any previous settings including manual settings. The only exception to this sequence is in the case of VLAN IDs. In the case of VLAN IDs, LLDP settings of VLAN IDs are the absolute authority. Then the usual sequence applies through TFTP or HTTP as appropriate. If the VLAN ID is not zero, any VLAN ID from the media server is ignored.

Administering H.323 and SIP IP Telephones on the Same Network

Both H.323- and SIP-based telephones can run on the same LAN or VLAN without difficulty. You can even mix H.323 phones and SIP phones having the same model, for example, the 4620SW. However, any given telephone supports only one signaling protocol at a time. You must therefore ensure that the proper application files (the software that runs in the telephone) are sent to the appropriate telephones. For information on downloading the software to the telephones, see Choosing the Right Application File and Upgrade Script File later in this chapter.

In general, H.323 and SIP telephones use the same administration mechanisms, with the exception that H.323 phones get some telephony administration from the Avaya call server. If you intend to mix H.323 and SIP telephones on the same network, you can use common information in either DHCP or in a common script file for those settings common to both types of sets. Because settings not applicable to a given telephone set are ignored, you can send SIP-specific settings to an H.323 telephone and H.323 settings to a SIP telephone without creating problems.
