UCM6100, which can be configured in the global ring timeout setting

The default setting
is enabled.

is disabled.

SIP Settings
NAT
Use NAT when the UCM6100 is on a public IP communicati
ng with
devices hidden behind NAT (e.g., broadband router). If there is one-way
audio issue, usually it's related to NAT configuration or Firewall's support
of SIP and RTP ports. The default setting is enabled.
Can Reinvite
By default, the UCM6100 will route the media steams from SIP
endpoints through itself. If enabled, the PBX will
attempt to negotiate
with the endpoints to route the media stream directly. It
is not always
possible for the UCM6100 to negotiate endpoint-to-
endpoint media
routing. The default setting is "No".
DTMF Mode
Select DTMF mode for the user to send DTMF. The default setting is
"RFC2833".
If "Info" is selected, SIP INFO message will be used. If
"Inband" is selected, 64-kbit
PCMU and PCMA are required. When
"Auto" is selected, RFC2833 will be used if offered, otherwise "Inband"
