Configuring Network Settings

HTTP Port Range

Specifies the HTTP port range (offset from the HTTP Port Start) used to support remote office IP phone UI and Web UI connections. Default is 100.

If UPnP is not enabled, then the only HTTP port that must be forwarded from the public/external side of the network to the AastraLink is the single port specified in the HTTP Port Start field. (If you disable UPnP, then HTTP Port Range is automatically disabled as well.)

SIP Port Start

Specifies the base port number for SIP connections (default = 5060). This port must be forwarded to the AastraLink from the public/external side of the Internet gateway/router for SIP trunk and remote office calls to succeed. If UPnP is enabled, then port forwarding is attempted automatically.

SIP Port Range

Specifies the number of ports to attempt SIP connections (default = 1, port 5060 only).

RTP Port Start

Specifies the public network first RTP port of the range on the router that the AastraLink uses to communicate with IP phones for external SIP calls. Default is 3000. This is the start of the range of UDP ports (from 'RTP Port Start' to 'RTP Port Start + RTP Port Count' that must be forwarded to the AastraLink from the public/external side of the Internet gateway/router for SIP trunk and remote office calls to succeed. If UPnP is enabled, then port forwarding is attempted automatically (see the RTP Port Range parameter).

RTP Port Range

Specifies the RTP port range (offset from the RTP Port Start) used to support the voice path for remote office IP phones and SIP trunk calls. Default is 300.

UPnP will attempt to allocate and forward the number of external ports specified by RTP/RTCP Port Count. Forwarded ports lie within the range: RTP Port Start through (RTP Port Start + RTP Port Range).
