Same result as obtained from another member. If the signal is strong enough, the performance of GOIP is alright. Is there any menas to increase the sentitivity of antenna?
I think one reason for GOIP sensitive to the signal strength is that GOIP's DSP coprocessor is not good for codec task or poor programmed. In the GSM FXO + SPA3102, each one follows its own timing specification and the total delay has good margin.
