Introduction

Network Diagram for an FXS Application

Image Added


Use the following parameters tables to configure the gateway the SIP FXS User Agent with global configurationsconfiguration settings. 

SIP Configuration

ParameterDescription

Enable-SIPUA

Default is False. This field enables or disables the gateway SIP FXS User Agent feature. 
Max-UA-Port

This field defines the maximum number for the number of FXS port ports that your deployment supports.

This field has a value of 22 when an FXS/FXO card is present.

This field has a value of 24 when an FXS card is present.

The value should not be changed.

SIP-SERVER-IP

This field is read-only

. The value represents

and is hard-coded to a value of 169.254.1.120. This is the SWe Edge internal IP address (Ethernet 2 IP address) used for SIP signaling

communication (

to and from the SIP User Agent (SIP-UA-IP address, 169.254.1.

120

100) to support FXS calls.

SIP-UA-IP

This field is read-only

. The value is

and is hard-coded to a value of 169.254.1.100. This

field represents

is the SIP

-UA SIP signaling

User Agent internal IP address used for

communication with SWe Edge

SIP signaling to and from the SWe Edge (SIP-SERVER-IP address, 169.254.1.120) to support FXS calls.

SIPUA-Bind-Port

Default is the internal port 1025 (including when the field is left empty). The range is 0 to 65535.  Enter a port number to which SIP UA binds and listens for SIP messages. 

Note: You can use port 5060 in IAD mode or bind-to-WAN. In all other cases, port 5060 cannot be used here.

SIP-User-Domain

Default is blank. The default indicates that all FXS ports use the system's ALG LAN IP address as the domain unless the value is overwritten at the port level. Each FXS port will be provisioned in the Softswitch domain, and the SIP-User domain is domain is also the authentication domain for each FXS port. 

Enable-Register

Default is True. Select the checkbox the 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-SIP-Authentication-NameDefault is False. When selected, the value configured for the port's username is used for the port's registration request.
Enable-PRACK

Default is False. When enabled, PRACK and UPDATE are advertised in the SIP Supported header, and support for the SIP option Tags “100rel” and “timer” is enabled. 

SIPUA-Instance-ID

Default is True. If set to true, the SIP Instance parameter is added to SIP Contact header.

Use-REFER-For-Transfer

Default is True. Select True Select True if your VoIP switch supports REFER requests as outlined in RFC3515 to perform call transfer.

Note: For release 24.1, this value should always be set to True.

Tone Configuration

ParameterDescription
Ignore-FAX-Over-Audio

Default is False. Select the checkbox to specify that an initial FAX request be ignored and to establish an audio call instead. On calls terminating onto a FXS port, in rare cases a FAX request can arrive in the initial INVITE message.

Unless this option is specifically needed, this field should be left as False. 

Disable-T38-RejectDefault is False. By default, a SIP 488 reject response is sent when T38 offer comes and T38 FAX support is disabled, followed by a G711 response. When set to True, a 488 response will not be sent, only a G711 response.
Enable-ADTRAN-T38-INTEROPDefault is True. When True, Redundance Recovery mode is forced for better interop.
Enable-T38-Offer-Outbound

Default is False. If FAX is detected, the recommendation is to have the Receiving T38 gateway always offer T38. Note that some implementations of the software might break if T38 is not offered. When enabled, the sending gateway will offer T38. 

Disable-RFC2833Default is False. If True, the FXS port do not advertise the telephone-event in SDP offer.
Enable-RFC2833-IBDefault is False. If RFC2833 is disabled by Disable-RFC2833, you can enable this attribute to still answer with RFC-2833. 
RFC2833-Event-Payload

Default is 101. The range is 100 to 101. This field allows you to define a telephone-event payload with any value.

...

ParameterDescription
RTP-Min-PortDefault is 22000. The range is 20000 to 65535. Enter the minimum number of RTP ports that SIP UA uses for media.
RTP-Max-PortDefault is 41600. The range is from 1 to 65535. Enter the maximum number of RTP ports that SIP UA uses for media.
Codec-Preference

Default is G7110-uLaw. Choose a codec type from the Codec Preference drop-down list. Edgemarc The Edge 8300 chooses this codec when offered by the far end regardless of the order of appearance in the SIP SDP.

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 ulawG.711 alawG.729G.728G.726,16 Kbps G.726, 24 Kbps G.726, 32 Kbps G.726, 40 Kbps.

Use-Preferred-Codec-Preference

Default is False. Select the checkbox for this field to specify that only the preferred codec is used when the FXS places a call. If an incoming call does not have the preferred codec, the call is rejected.

Enable-Access-CodeDefault is False. By default ‘#’ is used to auto-terminate dialing on FXS port. If ‘#’ is required as part of dial-pattern for access-codes, this field should be set to true.
VAD-EnabledDefault is Enabled. Choose whether to enable voice activity detection globally. 
Jitter-Buffer-ValueDefault is 60 msec. The range is 10 to 90 msec. This field defines the Jitter Buffer value in unit of msecs.
