There might also be other Huawei models having the = same issue. I traced the issue down to "^DDSETEX" AT command, which is used to = notify the device to start streaming audio. It seems that Ofono sends = this command too early on incoming calls. The command should always be = sent *after* the dial "D" or answer "A" command. The patch fixes this = behavior and afterwards voice will also work on E173u-2.
