Realm For Digest
Authentication
Configure the host name or domain name for the UCM6510. Realms
MUST be globally unique according to RFC3261. The default setting is
Grandstream.
Bind UDP Port
Configure the UDP port used for SIP. The default setting is 5060.
Bind IP Address
Configure the IP address to bind to. The default setting is 0.0.0.0, which

Allow Guest Calls
If enabled, the UCM6510 allows unauthorized INVITE coming into the
PBX and the call can be made. The default setting is "No".

"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".

Outbound Calls

UCM6510. The default setting is "Yes".
