回複：configuration頁裏的phone一項可以調換哪條線為默認線。

剛明白這個"*"的意義了，原來以為隻是代表電話鍵盤的*，後來看到wiki的解釋，對於linksys，還有另一層含義：
If IP dialing is enabled, one can dial [user-id@]a.b.c.d[:port], where ‘@’, ‘.’, and ‘:’ are dialed by entering “*”, user-id must be numeric (like a phone number) and a, b, c, d must be between 0 and 255, and port must be larger than 255. If port is not given, 5060 is used. Port and User-Id are optional.

這樣，|<:*1>8[8760][8760]xxxxxxx<:@proxy01.sipphone.com>|就好理解了，如果電話鍵盤撥號8005557777，那麽就轉換成*18005557777，由於前麵這時候允許Gizmo5的IP撥號。不過，就是我在Gizmo5的賬戶裏麵，call history沒有見到這個800號的撥號記錄，不知道是何緣故
