SIP SETTINGS

Table 96: 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 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 UCM6100 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 UCM6100 address to dial into the UCM6100.
If set to "No", all transfers initiated by the endpoint in the UCM6100 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
the URI in the "From:" header will be filled with this value.
If disabled, the UCM will not forward the diversion header.

Table 97: SIP Settings/Misc

Configure the register retry timeout (in seconds). The default setting is 20.
Configure the number of registration attempts before the UCM6100 gives up. The
default setting is 0, which means the UCM6100 will keep trying until the server
