Configure the host name or domain name for the UCM630X. Realms MUST be
globally unique according to RFC3261. The default setting is Grandstream.
Configure the UDP port used for SIP. The default setting is 5060.
Configure the IPv4 address to bind to. The default setting is 0.0.0.0, which means
binding to all addresses.
Configure the IPv6 address to bind to. The default is : "[::]" and it means to bind
to all IP addresses.
If enabled, the UCM630X allows unauthorized INVITE coming into the PBX and
the call can be made. The default setting is "No".
Warning:
Please be aware of the potential security risk when enabling "Allow Guest Calls"
as this will allow any user with the UCM630X address to dial into the UCM630X.
If set to "No", all transfers initiated by the endpoint in the UCM630X will be
disabled (unless enabled in peers or users). The default setting is "Yes".
When sending MWI NOTIFY requests, this value will be used in the "From:"
header as the "name" field. If no "From User" is configured, the "user" field of
the URI in the "From:" header will be filled with this value.
If disabled, the UCM will not forward the diversion header.
If enabled, collect calls will be blocked.
Note: Collect calls are indicated by the header "P-Asserted-Service-Info: service-
code=Backward Collect Call, P-Asserted-Service-Info: service-code=Collect
Call".

Outbound SIP Registrations
Configure the register retry timeout (in seconds). The default setting is 20.
Configure the number of registration attempts before the UCM630X gives up. The
default setting is 0, which means the UCM630X will keep trying until the server
side accepts the registration request.
