Parameter Description
Dialing Mode
[IsTwoStageDial]
One Stage [0] = One-stage dialing.
Two Stage [1] = Two-stage dialing (default).
Used for IPMP-10x/FXO gateways calls.
If two-stage dialing is enabled, then the FXO gateway seizes one of the PSTN/PBX
lines without performing any dial, the remote User is connected over IP to
PSTN/PBX, and all further signaling (dialing and Call Progress Tones) is performed
directly with the PBX without the gateway’s intervention.
If one-stage dialing is enabled, then the FXO gateway seizes one of the available
lines (according to Channel Select Mode parameter), and dials the destination
phone number received in Setup message. Use the ‘Waiting For Dial Tone’
parameter to specify whether the dialing should come after detection of dial tone, or
immediately after seizing of the line.
