Hi, The first patch is to handle right bracket in at command parser. It's identical with the previous patch I sent in the list. The second patch depends on the first one so I resend it again. It implements voicecall driver for handsfree profile and use AT+CIEV indicator to notify call status change. A field 'struct ofono_call *call' that point to the current call is used to avoid searching call list each time. A boolean 'mpty_call' is to indicate whether it is multi call or single call. The first version only supports single call. The multicall patch will be based on this patch. Please review it. Regards, Zhenhua
