Well, I suppouse it may be better and it's more logical to execute the
command only when a call connects but I was doing some testing and found
that worked better setting the echo supression on every transition :)

That's a good idea, but I think the issue may be a bit different. With 
Qtopia people were reporting no echo for the first call, but echo on 
subsequent calls. Since we're using an undocumented feature of the modem 
we don't know under what conditions it might be disabled, even though we 
don't disable it explicitly. Currently we only set the echo suppression 
in init, while this patch sets it on every call state transition. It may 
be worth moving it down a few lines so it only happens when a call 
connects, but this way we can be certain that echo suppression is 
enabled for every call.
