Airtel — no incoming call after porting from bsnl to airtel

Address:

679322

Message came that your porting was successful but no in coming calls or messages from other users are not coming. Outgoing calls are coming and message is being set data is working properly but no incoming calls.
When some one calls me it is saying that "the number you have called is note valid please check the number dialed"

Please resolve this problem as soon as possible
