推荐答案
传真通信选项，因为一开始就嵌入在GSM协议，这是自然的设计。是使用可选的GSM数据转院协议进行传真发送，所以它是个瘸子说，GSM音质不够好。
The fax communication option is embedded in GSM protocol since the very beginning, it's natural by design. Is uses optional GSM data tranfer protocol for fax transmission, so it was lame to say that GSM audio quality isn't good enough.
有没有模拟解调传真时都要通过GSM网络，将其转换为数字在进入供应商的PBX。
There's no analogue demodulation when fax goes over GSM network, it converts to digital on entering provider's PBX.
在默认情况下旧的好诺基亚9500也已实施基于Symbian的传真应用程序，完美的工作在任何GSM提供商。在一些供应商，你需要启用额外的电话号码，接收传真邮件，在某些手机上像西门子M55，你可以通过点击任何来电甚至主细胞系的菜单选项接收传真。
Get an old good Nokia 9500 it had implemented Symbian-based fax application by default, that worked perfect on any GSM-provider. On some providers, you needed to enable an additional phone number for receiving facsimile messages, on some phones like Siemens M55 you could receive fax by clicking a menu option on any incoming call even by main cell line.
我认为谷歌是负责为用户提供适当的GSM传真软件是免费的，因为之前大部分手机厂家做。通过搜索传真或传真游戏市场上的一切present是垃圾。
I think Google is responsible for providing users with an appropriate GSM faxing software for free, as most of the mobile manufacturers did before. Everything present on play market by search 'fax' or 'facsimile' is junk.
P.S。也有对VoIP线路传真发送一个特殊的协议，它是T.38或G.711直通;如果您的供应商/节点和硬件支持其中的一个，你是幸运的发送和接收传真的互联网连接，以及。例如。我自己的工作硬件的设置是兄弟9440 /行星VIP-156 / sipnet.ru。
P.S. There is also a special protocol for fax transmission on VoIP lines, it's T.38 or G.711 pass-through; if your provider/nodes and hardware supports one of those you are lucky to send and receive faxes over internet connection as well. Eg. my own working set of hardware is Brother 9440/Planet VIP-156/sipnet.ru.
