Table 35: SIP Extension Configuration Parameters -­ Media
Use NAT when the UCM6100 is on a public IP communicating 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.
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".
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" will be
used.
