Media
NAT
Use NAT when the PBX is on a public IP communicating with devices hidden behind
NAT (e.g., broadband router). If there is one-way audio issue, usually it is related to
NAT configuration or Firewall's support of SIP and RTP ports.
The default setting is enabled.
Enable Direct
Media
By default, the PBX 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 PBX 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 "RFC4733". If
"Info" is selected, SIP INFO message will be used. If "Inband" is selected, a-law or u-
law are required. When "Auto" is selected, RFC4733 will be used if offered, otherwise
"Inband" will be used.

ring tone to the UAS.
