有關caller ID的pass through

小弟有事請教:
如果用SPA3000作爲Elastix的pstn trunk, 從這個trunk打入的電話,如果接到某個ext上接聽,能不能看到pstn打入的caller ID?

謝謝!

看看下面信息是否能用上?

2: How do I verify the PSTN caller ID?*/
A: Your PSTN service must include caller-id service. You can enable the
< PSTN Ring Thru Line 1 > feature and connect a caller-id capable phone to Line 1
of the SPA-3000. When someone calls the PSTN line, the caller id will be passed
onto Line 1 when ringing through. For this, make sure < PSTN Ring Thru Delay >
is specified longer than the time it takes for the PSTN to complete delivery of
caller-id after the start of the 1st ring; 5s is a good choice for normal
US ring. Also make sure < PSTN Answer Delay > is set to larger than the time
it takes to show the caller-id on the device attached to Line 1 during
ring-thru after the start of the 1st PSTN ring. This should be at least 6s
larger than < PSTN Ring Thru Delay >. Default value is 16 seconds.

要给足够时间给SPA3000 detect和pass through。
