Choosing the Right Application File and Upgrade Script File

As mentioned in 4600 Series IP Telephone Scripts and Application Files, the 4600 IP Telephone software Releases are bundled together in *exe and *zip files on the Avaya support website. As of Release 2.0, there are 4 “bundles” from which to choose - only one bundle is likely to be optimal for any one environment.

The 4620SW IP Telephone supports multi-byte characters, so the software bundles come in one of three versions: a default version (which only supports single-byte characters like those used in English, French, Japanese Katakana, etc.), a multi-byte version for 4620SWs that supports Chinese and Russian, and a separate multi-byte version for 4620SWs that supports Japanese and Russian. If multi-byte support is not relevant to you, you want the default bundle, even if you do not have any 4620SWs. Otherwise, you want the software bundle that includes Chinese or Japanese, as appropriate.


NOTE:	All bundles include the complete software for the other, non-4620SW telephones (including the 4620 but not including the 4630/4630SW, which remains separate). The only differences between the three bundles are the software for the 4620SW, and a slight change in the associated upgrade script file.

The 4602 IP Telephones can support either H.323 or SIP signaling protocol. If a majority of your 4602s are H.323-based (the standard), or if you have no 4602s at all, you can use any of the software bundles identified above. If a majority of your 4602s are SIP-based, you want the fourth software bundle, identified as the “SIP” software bundle on the website. The application files in this SIP bundle are the same as in the default bundle, but the upgrade script file in the SIP bundle has been modified to assume that SIP is the default protocol for 4602s, and that H.323 is the exception.

If your environment contains a mixture of 4602 H.323 and SIP telephones, you will want to use the SIG system value to ensure each of those telephones have their appropriate software downloaded. The SIG system value has three legal values: the default value “0” (meaning “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 4602 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 - only on
a phone-by-phone basis. Instead, you should first instruct the installers of the non-default phones (that is, for installations of SIP phones in a largely H.323 environment, or vice versa) to carry out the SIGnaling Protocol Identifier procedure specified in Chapter 3 of the 4600 Series IP Telephone Installation Guide. For example, if yours is a largely H.323 environment for 4602s, when SIP phones are installed the SIG system value should be set to “2”. If yours is a largely SIP environment for 4602s, when H.323 phones are installed the SIG system value should be set
to “1”.

More detailed information about SIP is available in the SIP-related documentation, provided elsewhere on the Avaya support website.
