MP-20x Telephone Adapter
To "push" a configuration file and initiate an upgrade or downgrade:
1. Create a new configuration file that includes two important entries:
a. In rg_conf/rmt_upd/chech_sync_version, configure the details of the version to
which you want MP-20x to upgrade or downgrade, for example:
(rmt_upd
)
a. You may need to update the URL address from where MP-20x is downloading
the firmware (the path is configured in rmt_upd/url).
Note:
2. Place the file on the HTTP server.
3. Send the SIP NOTIFY message to MP-20x; MP-20x integrates the contents of the
new file and reboots. After rebooting, MP-20x compares the currently running version
with the version which is configured in rmt_upd/chech_sync_version and then
determines whether to connect to the rmt_upd/url for downloading the new rmt file.
Once the file is downloaded, it's headers are parsed, and only if it represents the
same version which was configured in the value of rmt_upd/chech_sync_version,
does the upgrade/downgrade process begin.
Version 3.0.1
(check_sync_version(2.6.0_build_1))
In the case of a downgrade, the service provider MUST put a configuration file
based on a template that matches the version to which the system is
downgrading.
