Hello,
You mentioned that your wife has filed a 498a case against you and your family. Did the police register a FIR? Did they tell it to you and did you file for anticipatory bail? If you have not done so yet, you should do so as quickly as possible, or otherwise you might be arrested and sent to jail. Before you try to call her again, you should make sure you are legally secure. There is no restriction on you calling her, but bear in mind that it might amount to harassment and even her relatives might then have grounds to file a case against you. It would be best if you try to negotiate the matter out of court and settle it in a mutually acceptable and amicable manner. You can approach the court for quashing of the cases under 498a stating that the proceedings have begun for an out of court settlement. You can even request for a court approved mediator to be provided to you. But before anything else, you should consult a lawyer and guarantee that you wont be sent to jail.
