Original public chan_dongle code working with asterisk 1.6 and 1.8.
Some known clones and external patches allow chan_dongle working with asterisk version up to 13.
Private chan_dongle support all available asterisk versions from 1.6 till 14.
At this moment, only Huawei models are supported. ZTE is on the road…
Note: Some users report bad voice quality using Centos 5 (i.e. Elastix). So, please, be careful with old kernels (i.e. 2.6.18)

For voice call feature, it's highly recommended the use of USB version 2.0
USB 1.1 can be work with USB 1.1 dongles
USB 3.0 working, but have limited number of devices per root hub
According to vendor specs, most usb modems have:
Almost every computer has USB ports where you can plug devices such as pen drives, bluetooth dongles, portable hard disks, etc. 3G modems can also be plugged, but power source may be a serious limitation. If your computer has several USB ports, you must check it can deliver all the power needed for your devices at the same time.
Normally, USB ports can deliver only 500 mA, so if you have more than one modem (or other hungry devices) plugged, it's possible you get stuck with strange problems.
Also, USB hubs can be a source of problems if you connect more than one 3G modem. 500 mA is not enough current for 2 or more dongles. In this case, external powered USB hub is recommended to avoid strange behavior, but be very careful with this, not any model is ok for this task. Some of them have serious problems with RF interferences from GSM side, making impossible to use chan_dongle.
Please, check list of compatible USB hubs
