UCM6510 IP PBX User Manual
Version 1.0.20.31
If enabled, the trunk CID will not be overridden by extension’s CID when
the extension has CID configured. The default setting is “No”.
Turn on this option when the PBX is using public IP and communicating
with devices behind NAT. If there is one-way audio issue, usually it is
related to NAT configuration or SIP/RTP port configuration on the firewall.
If selected, the trunk will be disabled.
Note: If a current SIP trunk is disabled, UCM6510 will send UNREGISTER
message (REGISTER message with expires=0) to the SIP provider.
If the trunk has an assigned PSTN telephone number, this field should be
set to "User=Phone". Then a "User=Phone" parameter will be attached to
the Request-Line and TO header in the SIP request to indicate the E.164
number. If set to "Enable", "Tel:" will be used instead of "SIP:" in the SIP
request. The default setting is disabled.
Configure the Caller ID. This is the number that the trunk will try to use
when making outbound calls. For some providers, it might not be possible
to set the CallerID with this option and this option will be ignored.
Important Note: When making outgoing calls, the following priority order
rule will be used to determine which CallerID will be set before sending out
the call: CID from inbound call (Keep Original CID Enabled) Trunk
Username/CallerID (Keep Trunk CID Enabled) DOD Extension
CallerID Number Trunk Username/CallerID (Keep Trunk CID Disabled)
Global Outbound CID.
Configure the name of the caller to be displayed when the extension has
no CallerID Name configured.
Configure the domain name of the SIP user account. This will overwrite
the domain in the "From" header. Example: If the user account is
"1234567", setting "trunk.UCM6510.provider.com" as the From Domain
value will result in the following From header:
"sip:1234567@trunk.UCM6510.provider.com"..
Configure the SIP transport protocol to be used in this trunk.
UDP
TCP
TLS
The default setting is "UDP".
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
