Ring Timeout
Configure the number of seconds to ring the user before
the call is
forwarded to voicemail (voicemail is enabled) or hang up (voicemail is
disabled). If not specified, the default ring timeout is 60 seconds on the
UCM6100
, which can be configured in the global ring timeout setting
under web GUI->Internal Options->IVR Prompt: General Preference.
The valid range is between 5 seconds and 600 seconds.
Note:
If the end point also has a ring timeout configured
, the actual ring
timeout used is the shortest time set by either device.
Technology
SIP
Select "SIP" if the users are using SIP or a SIP device.
The default
setting is enabled.
IAX
Select "IAX" if the users are using IAX or a IAX device.
The default
setting is disabled.
SIP Settings
NAT
Use NAT when the PBX 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 F
irewall's support of
SIP and RTP ports. The default setting is enabled.
Can Reinvite
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
"RFC2833"
. If "Info" is selected, SIP INFO message will be used. If
"Inband" is selected, 64-
kbit codec PCMU and PCMA are required.
When "Auto" is selected, RFC2833 will be used if offered, otherwise
"Inband" will be used.
Insecure
