MediaPack Series
1.2
General Gateway New Features
The device supports the following new gateway features:
1.
Immediate Release of Tel-to-IP Call when Device Receives 401/407 Response:
MP-124
MP-11x
FXS
FXO
If the device's default password has never been modified and an “Authentication
Required” SIP response (401/407) is received, the call is immediately released (and a
SIP Re-INVITE message is not sent).
2.
Play Busy Tone to IP Upon Call Failure (FXO):
MP-124
MP-11x
FXS
FXO
In previous releases, when the FXO device operated in Automatic Dialing mode, there
was no method to inform the caller that the Tel-to-IP call failed. The reason was that
the FXO device does not seize the line until a SIP 200 OK response is received. A new
option has been added which allows the device to play a Busy/Reorder tone to the
TDM line if a SIP error response (4xx, 5xx or 6xx) is received. The FXO device seizes
the line (off-hook) if a SIP error response is received and plays a Busy/Reorder tone to
the TDM side for the duration defined by the TimeForReorderTone parameter. After
playing the tone, the line is released (on-hook).
Relevant parameter: FXOAutoDialPlayBusyTone.
3.
Play Comfort Tone to FXS/FXO Endpoints:
MP-124
MP-11x
FXS
FXO
The device now supports the option to play a Comfort Tone to the FXS or FXO
endpoint. Typically, immediately after dialing is complete, a SIP INVITE message is
sent and after a certain period of time, a SIP 18x response is received. During this time
interval (i.e., after sending the INVITE and before receiving a 18x), the device plays a
Comfort Tone to the endpoint.
Relevant parameter: EnableComfortTone.
4.
Hold Timeout:
MP-124
MP-11x
FXS
FXO
The device now supports the option to keep a call on-hold for a user-defined time
before disconnecting the call.. If a hold request (SIP Re-INVITE) is received from the
IP side, a timer is started. Unless a Retrieve request is received, once the timer
expires the call is disconnected.
Relevant parameter: HeldTimeout.
