Since it looks like the Modem does actually provide some rudimentary 
unsolicited call state notifications via CIEV, you're better off just 
writing a custom driver.  CLCC polling logic is actually quite complex 
as it is, so adding vendor branching to it just makes things worse. 
Also the driver is likely to be much simpler if you can rely on 
unsolicited call state reporting events.

The send_clcc change does sort of make sense separately.
