1.音质不错(打开机子观看,其GSM部分是采用语音模块,和其它用数据处理模块有异,)
2.http://item.taobao.com/item.htm?id=12489660950
3.CHina GSM phone call HK phone
CHina GSM phone=>GSM GATEWAY=>Asterisk=>SIP trunk=> HK phone
That's what I want. Might I ask the following questions:
1. How about voice quality?
2. What exactly the GSM gateway you are using?
3. Could GSM phone dial out thru GSM phone=>GSM GATEWAY=>ET263=>ET263=>Asterisk=>SIP trunk=>Other destination?
