Choosing the Right Application File and Upgrade Script File

The 4600 IP Telephone software Releases are bundled together in *exe and *zip files on the Avaya support Web site. See 4600 Series IP Telephone Scripts and Application Files for a detailed description. As of Release 2.7, you have four “bundles” from which to choose. Only one bundle is likely to be optimal for any one environment.

Which bundle to choose depends on the answer to two questions:

• Which version of 4610SW/4620SW software do you need in that environment?
• Are the majority of your 4602/4602SW/4602SW+, 4610SW, 4620SW, 4621SW, and 4625SW Telephones in that environment H.323-based or SIP-based?

The 4610SW, 4620SW, 4621SW, 4622SW, and 4625SW IP Telephones support multi-byte characters, so the software bundles come in one of four versions:

• a default version which only supports single-byte characters like those used in English, French, Japanese Katakana, etc.
• a multi-byte version for 4610SW, 4620SW, 4621SW, 4622SW, and 4625SW IP Telephones that support Chinese, Russian, and Hebrew.
• a separate multi-byte version for 4610SW, 4620SW, 4621SW, 4622SW and 4625SW IP Telephones that support Japanese, Russian, and Hebrew. Note that the 4625SW does not currently support Japanese (Kanji).
• a separate multi-byte version for 4610SW, 4620SW, 4621SW, 4622SW and 4625SW IP Telephones that support Korean, Russian, and Hebrew.

If multi-byte support is not relevant to you, select the default bundle, even if you do not have any 4610SW, 4620SW, 4621SW, 4622SW, and 4625SW telephones. Otherwise, select the software bundle that includes Chinese, Japanese, or Korean as appropriate.

NOTE: All bundles include the complete software for the other, non-4610SW/4620SW/4621SW/4622SW/4625SW Telephones. The software includes the 4620 IP Telephone, but not the 4630/4630SW, which remains separate. The only differences between the four bundles are the software for the 4610SW, 4620SW, 4621SW, 4622SW, and 4625SW, and a slight change in the associated upgrade script file.

The 4602/4602SW/4602SW+, 4610SW, 4620SW, 4621SW and 4625SW IP Telephones can support either H.323 or SIP signaling protocols. If a majority of your 4600 Series IP Telephones are H.323-based, which is the most common situation, you can use any or all of the software bundles identified in this section. If a majority are SIP-based, select the fourth software bundle, identified as the “SIP” software bundle on the Web site. The application files in this SIP software bundle are the same as in the default bundle. The difference is a modified upgrade script file that assumes SIP is the default protocol for 4602/4602SW/4602SW+, 4610SW, 4620SW, 4621SW, and 4625SW IP Telephones, and that H.323 is the exception.

When you have a mixture of H.323 and SIP telephones, use the SIG system value to ensure that each telephone type has appropriate software downloaded. The SIG system value has three legal values:

• the default value “0” which indicates “use the default protocol,”
• “1” meaning “use H.323,” and
• “2” meaning “use SIP.”

You decide the meaning of “the default protocol.” If the majority of your IP telephones are H.323-based, that should be the default. Otherwise, SIP is the default.

The SIG system value cannot be set in the 46xxsettings file or in the upgrade script file. SIG can only be set on a telephone-by-telephone basis. Instead of manually setting SIG yourself, first instruct the installers of the non-default phones to perform the SIGnaling Protocol Identifier procedure in Chapter 3 of the 4600 Series IP Telephone Installation Guide. For example, if yours is a largely H.323 environment, when SIP phones are installed the SIG system value should be set to “2.” If yours is a largely SIP environment, when H.323 phones are installed the SIG system value should be set to “1.”

Detailed information about SIP is available in the SIP-related documentation, provided elsewhere on the Avaya support Web site.

NOTE: As indicated above, although the SIG system value is a Release 2.0 feature, the 4601 IP Telephone supports SIG functionality, even though the 4601 currently supports only Release 1.8 software.
