ATA Connectivity Requirements
NOTE
Cisco Small Business ATA Administration Guide
• 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
