问题请教：回复：自裝網路電話

我刚买了unlocked Linksys PAP2. 设置如下(line2)

Outgoing - using VoipDiscount - Works great
Incoming - Using CallCentric ->(DID Forward)->VoipDiscount

问题：
如果我先打出去， 接通，挂断。再打进来就没有问题。
可等一会，再打进来就打不通了。But the report shows the incoming call with 0 minutes (whick means the callcentric works fine, but my phone doesn't ring)


是不是我的ATA没有设对??

谢谢
