Provisioning & Zero Config; Auto Discovering - Grandstream Networks UCM6 Series Basic Configuration Manual

PROVISIONING & ZERO CONFIG
Grandstream SIP Devices can be configured via Web interface as well as via configuration file through
TFTP/HTTP/HTTPS download. All Grandstream SIP devices support an XML format configuration file. The
UCM6XXX provides a Plug and Play mechanism to auto-provision the Grandstream SIP devices in a zero
configuration manner by generating XML config file and having the phone to download it. This allows users to
finish the installation with ease and start using the SIP devices in a managed way.
To provision a phone, three steps are involved, i.e., discovery, assignment and provisioning. The UCM6XXX
creates XML config file to the detected/assigned Grandstream device and accomplishes the following
configurations on the device after the provisioning:

A UCM6XXX extension will be assigned and registered on the phone.

SIP-related network settings such as "NAT traversal" and "Use Random Port" are configured on the
phone.

Call settings such as "Dial Plan" and "Auto Answer".

LDAP client configurations will be set up automatically on the phone to use the default LDAP directory
generated in the UCM6XXX LDAP server.
This section explains how zero config works on the UCM6XXX. The settings for this feature can be accessed
via Web GUI  Value-added Features Zero Config.

Auto Discovering

When referring back to our typical scenario in the beginning of this tutorial, we know that there is a GXP2135
connected to the LAN side of the UCM62xx series. The UCM6XXX series LAN interface has DHCP enabled
and has assigned the GXP2135 with an IP address. By default, the IP assigned would be within the 192.168.2.X
range. When the UCM6XXX series offers an IP address to the phone it also offers DHCP Option 66, which
provides the phone with a config server path that points to the UCM6XXX series. All of Grandstream VoIP
devices have Option 66 turned on by default and this is how the GXP2135 was discovered by the UCM6XXX.
Upon being discovered, the GXP2135 will provide details about its MAC, IP Address, Version (Firmware),
Vendor, Model, Connection Status and Create Config. By navigating to Value-added Features Zero Config,
a user will be able to see the discovered device(s).
