286.Let me tell you how it should work: I have assigned a phone number, that when it is picked-up, the IVR from the AS5350 router respods and after the press of a key it sends the packages to the HandyTone and from there to a normal phone; So far so good because it partialy works, that means that the phone rings butt there is no voice. I have managed to solve this problem using a hardware Sip Server between the two devices ( in this way both HT286 and AS5350 act as clients), but this is not possible any more because it was not my server; so i have tried with a software solution and I&#39;ve installed SER. As I said before , I haven&#39;t managed to configure&nbsp; it to work as I wish and this is why I&#39;am asking for your help; it would realy help me if you can provide a 
ser.cfg example that would do just the routing part (no ack no authentification , no mysql,...., just routing).<br>Please excuse my bad english.<br>Thank you very much !<br>
