SIP

Check SIP if the user is using SIP or a SIP device.

IAX

Check IAX if the user is using IAX or a IAX device.

Analog Station

Select the port number if the user is attached on the analog port of the

PBX.

SIP Settings

NAT

Use NAT when the PBX is on a public IP communicating with devices

hidden behind NAT (e.g., broadband router). If there is one-way audio

issue, usually it's related to NAT configuration or Firewall's support of

SIP and RTP ports.

Call Reinvite

By default, the PBX will route the media steams from SIP endpoints

through itself. If enabled, the PBX will attempt to negotiate with the

endpoints to route the media stream directly. It is not always possible for

the PBX to negotiate endpoint-to-endpoint media routing. The default

setting is No.

DTMF Mode

Select DTMF mode for the user to send DTMF. The default setting is

RFC2833. If "Info" is selected, SIP INFO message will be used. If

"Inband" is selected, 64-kbit codec PCMU and PCMA are required.

When "Auto" is selected, RFC2833 will be used if offered, otherwise

Inband will be used.

Insecure

 Port: Allow matching peers by IP address without matching port

number.

 Invite: Authentication of incoming INVITE messages is not required.

 No: Normal IP-based matching and authenticated INVITES.

The default setting is Port.

Enable Keep-alive

If enabled, keep the NAT session open. The default setting is enabled.

Keep-alive Frequency

Configure the number of seconds for the host to be up for Keep-alive.

Other Settings

SRTP

Enable SRTP for the call.

FAX Detect

Enable to detect fax signal from the user/trunk during the call and send

the received fax to the Email address configured in this configuration

page. If no Email address can be found for the user, send the received

fax to the default Email address in FAX setting page.

Note:

If enabled, FAX cannot use Passthrough.

Strategy
