SIP UA enables analog phones at each FXS port to make IP or PSTN calls. Each FXS port represents an instance of a SIP user agent. Once configured, each FXS port registers to the configured domain using outbound proxy. If registration is successful, the phone at the FXS port will have a dial tone.

Note

You must enable SIP UA service to configure SIP UA ports.

  1.  Choose VoIP > SIP > SIPUA.

  2. Select the Enable SIPUA checkbox and click Submit.

    A message indicates that service will be temporarily interrupted.

  3. Click OK to confirm. Fields on the FXS/Phone Port Settings - Basic page become active.

  4. Configure settings using the information in the following table as a guide.

    FXS/Phone Port Settings - Basic

    ItemDescription

    Global Configuration

    Settings apply to all ports.

    Enable SIPUA

    Select the Enable SIPUA checkbox if it is not already checked.

    Use SIP Username for SIP authentication

    Select the Use SIP Username for SIP authentication checkbox to enable SIP authentication when authenticating an FXS port.

    Codec Preference

    Choose a codec type from the Codec Preference drop-down list.

    This selects the codec that is used by all FXS ports for encoding analog data. The codec must be part of the negotiated codec list:

    G.711 ulaw

    G.711 alaw

    G.729

    G.728

    G.726,16 Kbps

    G.726, 24 Kbps

    G.726, 32 Kbps

    G.726, 40 Kbps.

    Use preferred codec only

    Select the Use Preferred codec only checkbox to specify that the system use only the preferred codec type.

    This specifies that only the preferred codec is used when the FXS places a call.

    Use REFER for transfer

    Select the Use REFER for transfer checkbox if your VoIP switch supports REFER requests as outlined in RFC3515 to perform call transfer.

    Use SIP INFO for hook-flash

    Note: Available on EdgeMarc 250 only.

    Select the Use SIP INFO for hook-flash check-box to send SIP INFO to notify VoIP switch.

    Register with proxy

    Select the Register with proxy checkbox to instruct each configured FXS port to send a REGISTER request to the configured domain through a configured outbound proxy. If this checkbox is not checked, FXS ports will not register.

    Note: Some VoIP deployments use static registration for the FXS ports and do not require port registration.

    Enable Dry-Closure (FXO-FXS)

    Note: Available on EdgeMarc 250 only.

    Specifies FXS port 4 to connect to the FXO port (known as “dry closure”) during a power failure.

    For systems licensed with less than four ports, user phones are connected to FXS ports 1-3 and can be completely disconnected from the FXO port to allow dry closure.

    To connect the FXO port to one of the FXS phones during a power failure, swap the port 1 license to port 4.

    Port Level Basic Configuration
