SIP SETTINGS

Table 51: SIP Settings/General

Configure the host name or domain name for the UCM6510. 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 UCM6510 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 UCM6510 address to
dial into the UCM6510.
Select to enable overlap dialing support. Overlap dial provides for a
longer time-out period between digits, also called the inter-digit timer. If
set to "Yes", the PBX expects to receive the digits one right after the
other coming in to this line with very little delay between digits. If set to
"No", the PBX waits up to about 2 seconds between digits. The default
setting is "No".
If set to "No", all transfers initiated by the endpoint in the UCM6510 will
be disabled (unless enabled in peers or users). The default setting is
"Yes".
Select to enables DNS SRV lookups on outbound calls from the
UCM6510. 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.
Configure the domain for the UCM6510. Incoming INVITE and REFER
messages can be matched against a list of "allowed" domains, each of
