To share my experience of 如何能让一个ATA input 联接多个电话呢

谢谢fitwxc, 我也成功地装上了ATA phone.
To share my experience of 如何能让一个ATA phone jack 联接多个电话呢？Here is what I did:　
联接ATA output with any phone jack in house, so the whole house phone jacks are connected to ATA output. You can connect to the rest of phone jacks with your regular phones (Not cordless phone). When someone dials your ATA phone, all the phones in your house will ring at the same time. You can pick up any phone to answer the call. You do not need to run all the way to ATA phone in order to answer the call. Hope that help.
