Provisioning Cisco Small Business VoIP Devices
Provisioning Overview
Cisco Small Business IP Telephony Devices Provisioning Guide
The Restricted Access Domain parameter is configured with the actual domain
names of up to a maximum of five domains. The Primary_DNS and
Secondary_DNS parameters are configured with the actual domain names or IP
addresses of the DNS servers available to the RC unit.
Redundant Provisioning Servers
The provisioning server can be specified as an IP address or as a fully qualified
domain name (FQDN). The use of a FQDN facilitates the deployment of redundant
provisioning servers. When the provisioning server is identified through a FQDN,
the IP Telephony device attempts to resolve the FQDN to an IP address through
DNS. Only DNS A-records are supported for provisioning; DNS SRV address
resolution is not available for provisioning. The IP Telephony device continues to
process A-records until the first server responds. If no server associated with the
A-records responds, the IP Telephony device logs an error to the syslog server.
Retail Provisioning
The firmware for each IP Telephony device includes an administration web server
that displays the internal configuration and accepts new configuration parameter
values. The server also accepts a special URL command syntax for performing
remote profile resync and firmware upgrade operations.
In a retail distribution model, a customer purchases a Cisco Small Business voice
endpoint device and subscribes to a particular service. The customer signs on to
the service and establishes a VoIP account, possibly through an online portal with
an Internet Telephony Service Provider (ITSP). The customer binds the device to
the assigned service account.
The unprovisioned IP Telephony device is instructed to resync with a specific
provisioning server through a resync URL command. The URL command typically
includes an account PIN number or alphanumeric code to associate the device
with the new account.
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
PIN number for the new account is 1234abcd. The remote provisioning server is
configured to associate the IP Telephony device that is performing the resync
request with the new account, based on the URL and the supplied PIN.
