Converting An H.323 Set To Sip; Automatically Upgrading All H.323 Telephone Sets - Avaya 4602 Administrator's Manual

Administering 4602 SIP Telephones

Converting an H.323 Set to SIP

These steps assume you have a working H.323 environment. Before you begin the upgrade, be
sure that you have:
Preloaded the configuration HTTP server with the required SIP configuration
(i.e., sip_4602D01A.txt), SIP application (sip_4602apXXXX.ebin), and SIP boot binary
(i.e., sip_4602btXXXX.ebin) files. All files must be in the root of the server
(i.e., http://192.168.0.1/sip_4602D01A.txt).
Ensured that the SIP configuration file on the configuration HTTP server properly sets the
AppName and BootName parameters.
Set the DHCP server with a Site-Specific Option Number of 172 that specifies the
parameter ConfigHttpSrvr (i.e., ConfigHttpSrvr=192.168.0.100).
If you do not use the DHCP SSON to configure the HTTP server address, you must
manually set the HTTP server's address. To set the server address manually, use the local
SETUP command at each phone, or use the Web interface to set up the ConfigHttpSrvr
value properly in each phone.
Web Interface
Preloaded the special conversion version of the SIP boot binary (i.e., 323tosipXXXX.bin)
and the appropriate script file (i.e., 46xxupgrade.scr) onto the TFTP server.

Automatically Upgrading All H.323 Telephone Sets

Follow these steps to automatically upgrade all H.323 telephone sets:
1. Modify the H.323 script to always download the special conversion version of the boot
binary 323tosipXXXX.bin instead of the regular H.323 boot application.
2. Restart the phones via the switch.
3. When the phones restart, they download and run the special SIP conversion boot file,
restart again, and then attempt to download a configuration file from the HTTP server.
4. The Configuration file points the phones to the new SIP boot and application binaries, which
will be downloaded.
5. After the phones restart, they run using SIP.
