Last week I bought the SHARPVISION ONT Model No: AS-341-WT and it was configured by the BSNL-franchise-man for internet and it is working fine. But he did not configure for VOIP (i.e) I am not able to make calls from the phone attached to the above said router. Anybody, kindly inform me(e-mail: [email protected]) the procedure for configuring the VOIP in the above said router. Thanks.
