UCM6200 Series User Manual
Version 1.0.20.38
"trunk.UCM6510.provider.com" as the From Domain value will result in the
following From header: "sip:1234567@trunk.UCM6510.provider.com".
From User
Configure the username of the account. This will overwrite the user value in the
From header. This is useful for scenarios where a single user account has
multiple DIDs. Example: If the domain is "trunk.UCM6510.provider.com", setting
"1234567" as the
From User value will result in the following From header:
"sip:1234567@trunk.UCM6510.provider.com".
Username
Enter the username to register to the trunk from the provider when "Register SIP
Trunk" type is selected.
Password Enter the password to register to the trunk when "Register SIP Trunk" is selected.
Auth ID Enter the Authentication ID for "Register SIP Trunk" type.
Auth Trunk
If enabled, the UCM will send 401 response to the incoming call to authenticate
the trunk.
Auto Record
Enable automatic recording for the calls using this trunk (for SIP trunk only). The
default setting is disabled. The recording files can be accessed under Web
GUI
→ CDR → Recording Files .
Direct Callback
Allows external numbers the option to get directed to the extension that last called
them.
For Example: User 2002 has dialed external number 061234575 but they were not
reachable, once they have received missed call notification on their phone, they
would mostly call back the number, if the option “Direct Callback” is enabled then
they will be directly bridged to user 2002 regardless of the configured inbound
destination.
