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
