NOTE
You can use line 1 or line 2 to access the IVR functions.
For proper operation, the service provider should use an Outbound Proxy to
forward all voice traffic when the SPA8000 is located behind a router. If
necessary, explicit port ranges can be specified for SIP and RTP.
The SPA8000 is not designed to forward IP packets to devices connected to its
AUX port and that configuration is not supported.
The SPA8000 also can be configured with trunk groups and trunk lines. See
SIP Trunking and Hunt Groups on the SPA8000, on page 70.
