刚明白这个"*"的意义了,原来以为只是代表电话键盘的*,后来看到wiki的解释,对于linksys,还有另一层含义:
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.
这样,|<:>8[8760][8760]xxxxxxx<:>|就好理解了,如果电话键盘拨号8005557777,那么就转换成*18005557777,由于前面这时候允许Gizmo5的IP拨号。不过,就是我在Gizmo5的账户里面,call history没有见到这个800号的拨号记录,不知道是何缘故
