Have you tried the latest firmware on this?.....(also does it use any kind 
of special software driver?)

Another problem here as well.

As well as ATZ not working the modem refused to dial as well, possibly if 
we ignore the first error(the ATZ) then it will only reach ATDT and then 
stop again.

Perhaps connect to the modem using minicom/cu/kermit and manually send the 
AT&F&W to see if it fixes things up....

Maybe:

if (!atCmd(conf.softResetCmd, AT_OK, conf.resetDelay)) {
         //report error here
         if (!atCmd("AT&F&W", AT_OK, conf.resetDelay)) {
                 //there's really no coming back from here - crash and burn.
         }
}
return atCmd(resetCmds, AT_OK, ms);
