For ‘Two Stage Dialing’ the MP-10x/FXO seizes the
next available PSTN/PBX line, without performing
any dial, the remote user is connected over IP to
PSTN/PBX, and all further signaling (dialing and call
progress tones) is done directly with the PBX without
Gateway intervention.
Usually the phone number received in Setup
message is not used, however
if ‘IsUseFreeChannel = 0’, the phone number
received in Setup, is used for seizing specific FXO
line that has same number.
Two Stage
Dialing,
IP ! FXO calls
Refer to the remote extension application note.
The FXO Gateway releases the call if busy or fast
busy (reorder) tone is detected on the FXO port.

Using out of band
DTMF signaling
over H.245 and
HookFlash
signaling
When using H.245 out of band signaling, disable
inband signaling (mute and don’t relay the digits). In
addition, disable the Q.931 sending.
Using “DTMFVolume = “ set the level of played
DTMF digits.
The HookFlash signal is detected at FXS endpoints
and generated at FXO endpoints, according to
“FlashHookPeriod = “ parameter.
Note: When using Fast Start the H.245 channel
remains close, and out of band signaling can’t be
used, unless “OpenH245onFS” is set to 1 or remote
Gateway/terminal opens the H.245 channel.

Open media only
on connect
This feature is useful when Tunneling or Fast Connect are used. Voice channel in
egress Gateway is opened immediately after sending an ALERT message. If this is not
the appropriate procedure, the User can set this parameter to “1”. to open voice
channel only after CONNECT is sent.
Using Hunt

TrunkGroup_x = a-b, <starting number>
IsUseFreeChannel
PSTNPrefix = <prefix>, <Hunt Group ID>
AddTrunkGroupAsPrefix
This feature can be used to define group of Gateway
ports, called hunt groups. For example:
TrunkGroup_1 = 1-4,100
TrunkGroup_1 = 8,200
TrunkGroup_2 = 5-7,300
