SIP SETTINGS

Table 84: SIP Settings/General

Configure the host name or domain name for the UCM6200. 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 UCM6200 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 UCM6200 address to dial into the UCM6200.
If set to "No", all transfers initiated by the endpoint in the UCM6200 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.

Table 85: SIP Settings/Misc

Configure the register retry timeout (in seconds). The default setting is 20.
Configure the number of registration attempts before the UCM6200 gives up. The
default setting is 0, which means the UCM6200 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.
Select to enable video support in SIP calls. The default setting is "Yes".
If enabled, when rejecting an incoming INVITE or REGISTER request, the
UCM6200 will always reject with "401 Unauthorized" instead of notifying the
requester whether there is a matching user or peer for the request. This reduces
the ability of an attacker to scan for valid SIP usernames. The default setting is
"No".
