SIP SETTINGS

Table 90: 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.
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".
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.

Table 91: SIP Settings/Misc

Configure the register retry timeout (in seconds). The default setting is 20.
Configure the number of registration attempts before the UCM6510 gives
up. The default setting is 0, which means the UCM6510 will keep trying
until the server side accepts the registration request.
Configure the maximum bit rate (in kb/s) for video calls. The default setting
is 384.
