I am unable to make an outgoing call using CTelephony:: DialNewCall, on CUG(Closed User Group) enabled SIMs on 9.2 & 9.1 devices. It always gives message 'Call Disconnected' & returns error code -2 in the RunL callback.
Whereas same code with CTelephony:: DialNewCall, is working fine on normal GPRS enabled SIMs without CUG settings.
Using CUG enabled SIM & RCall:: Dial, i was able to make an outgoing call. But since RCall is said to be deprecated i have to use CTelephony calls.
What could be the possible reasons?? Are there any restrictions for using CTelephony calls? or is there any other setting to be done specific to SIM?
