Note:
If a given parameter is administered in multiple places, the last server to provide
Note:
the parameter has precedence. The precedence is:
- manual administration,
- 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).
Any settings the IP telephone receives from FTP backup files, or in their absence, 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, the
usual sequence applies through TFTP or HTTP as appropriate. If the VLAN ID after
TFTP or HTTP 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 phone) are
sent to the appropriate telephones. For information on downloading the software to the
telephones, see
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 phone and H.323 settings to a SIP phone without creating
problems.
