Call Forwarding Support on SPA9000
SPA9000 supports the call forward scenarios listed in the following table.
SPA9000 supports call forward by client station:
• unconditionally
•when busy
•on no answer
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.
