Network issue with Galaxy S5 SM-G900FD

I'm using this phone in India with Aircel Dual SIMs.
Galaxy S5 SM-G900FD--KLTE Duos

SIM-1 : Aircel--WCDMA/GSM
SIM-2: Aircel--GSM

Only by SIM-1 , I'm able to make and receive calls...
SIM-2 if I use no audio at all......

On the other hand if I change SIM-2 to WCDMA/GSM, I'm able to make calls...
But SIM-1 if I use no audio....

Kindly suggest me a solution...
Already my device is rooted.
