我们的办公室最近安装了永久性Internet连接,它采用部分T1线路,我们还建立了自己的邮件服务器。是否有某种万法能够使系统接收电话呼叫,以便我们的员工在外出时可以通过免费的电话查看电子邮件?每次当我们从外面检查电子邮件时,都要支付到本地ISP的电话费,以及旅馆的附加费用。
Our office recently installed a permanent Internet connection, which uses part of the T1 line, and we also set up our own mail server. Is there any way to enable the system to receive phone calls so that our employees can view the e-mail over the free phone when they go out? Each time we check the e-mail from outside, we have to pay the local ISP’s phone bill, There is an additional charge for the hotel.
