Configuration Settings: Line
· DTMF Support: Default = Out of Band
DTMF tones can be sent to the remote end either as DTMF tones within the calls audio path (In Band) or a separate
signals (Out of Band). Out of Band is recommended for compression modes such as G.729 and G.723 compression
modes where DTMF in the voice stream could become distorted.
· Allow Direct Media Path: Default = On
This settings controls whether IP calls must be routed via the system or can be routed alternately if possible within the
network structure.
· If enabled, IP calls can take routes other than through the system. This removes the need for a voice compression
channel. Both ends of the calls must support Direct Media and be using the same protocol (H.323 or SIP). Enabling
this option may cause some vendors problems with changing the media path mid call.
· If disabled or not supported at on one end of the call, the call is routed via the system. RTP relay support allows
calls between devices using the same audio codec to not require a voice compression channel.
· Progress Ends Overlap Send: Default = Off.
Some telephony equipment, primarily AT&T switches, over IP trunks send a H.323 Progress rather than H.323
Proceeding message to signal that they have recognized the digits sent in overlap state. By default the system expects
an H.323 Proceeding message. This option is not available by default. If required, the value
ProgressEndsOverlapSend must be entered into the Source Numbers tab of the NoUser user.
· Default Name From Display IE: Default = Off.
