Table 85: SIP Settings/General

Configure the host name or domain name for the UCM6100. 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 IP address to bind to. The default setting is 0.0.0.0, which
means binding to all addresses.
If enabled, the UCM6100 allows unauthorized INVITE coming into the
PBX and the call can be made. The default setting is "No".

Calls" as this will allow any user with the UCM6100 address to dial into
the UCM6100.
Select to enable overlap dialing support. The default setting is "No".
If set to "No", all transfers initiated by the endpoint in the UCM6100 will be

Configure the domain for the UCM6100. Incoming INVITE and REFER
messages can be matched against a list of "allowed" domains, each of
which can direct the call to a specific context if desired. By default, all
domains are accepted and sent to the default context or the context
associated with the user/peer placing the call. Register to non-local
domains will be automatically denied if a domain list is configured. Up to
10 domains can be added.
