Hi All I have a client with 3 analogue gsm routers, one of which is a 'Fusion 100'. The other 2 routers work perfectly, but the 'Fusion 100' router refuses to dial. I can dial from an analogue phone connected to the router.>From the CLI in debug mode, I can see polarity switches when trying toinitiate the call. I have tried the answeronpolarityswitch and hanguponpolarityswitch settings in zapata.conf with no luck. I have a feeling it is to do with the timing parameters in zapata.conf. Does anyone know where to get more information on these parameters? Any ideas?
