Samsung Galaxy S Duos Calling problem through SIM1

I have a Samsung galaxy S duos S7562 dual sim mobile phone. Off late i am facing one peculiar problem. In my office, i am not able to make or receive any call through SIM1(It shows the message call ended after calling any number), where as i can make normal call through SIM2. The network of SIM 1 is OK. When i go outside of my office and make any call through SIM1, i am able to make call. But at the same time when i remove the SIM1 and put it on my old Nokia mobile, i am able to call and receive in my office also. Also my colleagues in the office are able to make call through the same Service provider as my SIM1 from the office itself. But i am not facing the problem in SIM2. I have tried to interchange the SIM1 with SIM2 also, but no improvements found. What could be the problem. Kindly suggest some solution as my SIM1 is my main no. and most of the time i spend in office

Contact you service provider for configuration & set up info

@camstuf
I don't think it is a configuration issue, as i can call from outside my office and from other places with the same configuration through SIM1. Also i am able to call from SIM2 from the office itself. So there must be some other issue.

Hi Guys,

I am also facing the same problem on mine S Duos. I have tried one solution i.e. putting SIM one in GSM mode only, but that is also not working in my case. Do any body got any other fix. Thanks to share the fix.
