Parameter Description
Dialing Mode
[IsTwoStageDial]
One Stage [0] = One-stage dialing.
Two Stage [1] = Two-stage dialing (default).
Used for IPÆFXO modules calls.
If two-stage dialing is enabled, then the FXO module 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 module 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.
