If CLCC is returning an error, there's no hope of the default plugin working.  
You will need to do some digging to figure out whether its possible to support 
this device.

For hangup oFono sends a AT+CHLD=1<callid>, which is most likely 1.  So 
AT+CHLD=11.  For busy, oFono sends AT+CHLD=0.  If these result in errors, the 
default plugin will not work.

It might be that the modem is using a neutered command set.  Can you find out 
whether CHLD=11 works, whether AT+CHLD=0 works, whether AT+CHUP works and 
whether ATH works?  Most likely this hardware will need a custom driver.
