Spok Messenger Ports: SMS

Creating the SMS Port

SMS ports allow connection via a modem for the transmission of SMS messages via the SMS gateway.

  1. Choose Interfaces > Ports. The Ports dialog displays.
  2. Click the New button to create a new port on the server. NOTE: When creating a port that has similar properties to an existing port, select the port of similar type before selecting New. Details specific to that port only are required.
  3. Enter the fields as described in the table below:


    In the Name field, enter a name to describe the port.


    From the Protocol list box, select the SMS option. The fields are automatically populated with the entries shown in the graphic.


    From the Type list box, select the Modem option depending on which model you have:

    • CMM Modem: Use for legacy 2G Fusion CMM
    • MultiConnect/CMM 3G: Use for the MultiConnect Cell 100 modems. This is also backwards compatible with the Fusion 3G CMM modems.
    • Wavecom GSM Modem: Use for legacy WMOD2 GSM Modem
    • MultiConnect 3GPP2: Used for MultiConnect Cell 100 3GPP2 Verizon modem.

    Serial Port

    From the Serial Port list box, select a port that is defined as being AVAILABLE. A port that is already assigned within Spok Messenger is labeled IN USE. A port in use by another application on the server is labeled UNAVAILABLE.

    Flow Control

    Set the Flow Control field to None.

    Initialization String

    Leave the Initialization String field blank.

    Dial String

    Leave the Dial String field blank.

    Answer After Modem Rings

    Leave this field set to 0 so it will not auto answer any inbound calls.


    This field is not required with the MultiConnect modem.
  4. Click Save to commit the new settings to the server. The new port configuration is saved.
  5. In order to reduce network traffic, the status of each of the serial ports is not automatically updated. Click Refresh to update the status of each port.
  6. Remember that the port is only the portal through which data travel. Once your port is configured, you still need to configure a SMS Gateway. Refer to SMS Gateways for more information.
