SPA9000 supports the call forward scenarios listed in the following table.
NOTE
When an incoming call from the ITSP is forked to multiple client stations, the
SPA9000 does not honor the 3xx response returned by any of the client stations. If
you wish the call to be forwarded to voicemail or another client station when it is not
picked up, you can specify the optional “cfwd=
target
” syntax in the Contact List.
