SIPSETTINGS/GENERAL
Table 83: SIP Settings/General 
Realm For Digest 
Authentication 
Configure the host name or domain name for the UCM6200. 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 
means binding to all addresses. 
Allow Guest Calls 
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. 
Allow Transfer 
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". 
MWI From 
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.

Outbound SIP Registrations 
Register Timeout  Configure the register retry timeout (in seconds). The default setting is 20.
Register Attempts 
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.

setting is 384.
