Deployment and Provisioning

Provisioning

supplied Customer ID. Through this initial resync operation, the phone is configured in a single step. The
phone is automatically directed to resync thereafter to a permanent URL on the server. For example:
https://prov.supervoip.com/cisco-init
For both initial and permanent access, the provisioning server relies on the phone client certificate for
authentication. The provisioning server supplies correct configuration parameter values based on the associated
service account.
When the device is powered up or a specified time elapses, the phone resynchronizes and downloads the latest
parameters. These parameters can address goals such as setting up a hunt group, setting speed dial numbers,
and limiting the features that a user can modify.

Resynchronization Process

The firmware for each phone includes an administration web server that accepts new configuration parameter
values. The phone may be instructed to resynchronize configuration after reboot, or at scheduled intervals
with a specified provisioning server through a resync URL command in the device profile.
By default, the web server is enabled. To disable or enable the Web server, use the resync URL command.
If needed, an immediate resynchronization may be requested via a "resync" action URL. The resync URL
command may include an account Customer ID number or alphanumeric code to uniquely associate the device
with the user's account.
Example
http://192.168.1.102/admin/resync?https://prov.supervoip.com/cisco-init/1234abcd
In this example, a device at the DHCP-assigned IP address 192.168.1.102 is instructed to provision itself to
the SuperVoIP service at prov.supervoip.com. The Customer ID number for the new account is 1234abcd.
The remote provisioning server associates the phone that is performing the resync request with the account,
based on the URL and Customer ID.
Through this initial resync operation, the phone is configured in a single step. The phone is automatically
directed to resync thereafter to a permanent URL on the server.
For both initial and permanent access, the provisioning server relies on the client certificate for authentication.
The server supplies configuration parameter values based on the associated service account.
Provisioning
A phone can be configured to resynchronize its internal configuration state to match a remote profile periodically
and on power-up. The phone contacts a normal provisioning server (NPS) or an access control server (ACS).
By default, a profile resync is only attempted when the phone is idle. This practice prevents an upgrade that
would trigger a software reboot and interrupt a call. If intermediate upgrades are required to reach a current
upgrade state from an older release, the upgrade logic can automate multistage upgrades.
