UCM630xA Series User Manual
Version 1.0.9.10
If enabled, this extension number can register, log in and use Wave normally,
otherwise it will not be able to use Wave, but the phone function will still be retained.
If enabled, this extension number will be displayed in the Wave contact, otherwise it
will not be displayed, and it cannot be found in the chat, but the user can still dial this
number.
Select voice prompt language for this extension. If set to "Default", the global setting
for voice prompt language will be used.
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.
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".
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.
When present in an INVITE request, the Alert-info header field specifies an alternative
ring tone to the UAS.
Enable/disable SRTP for RTP stream encryption.
