Hello Kannan Chandrasekar,
If the unit was working for one month you may still have warraty on it but I cannot remote diagnose this.
You have two Options:
- Contact Scansource in the USA and inquire about your warranty status
- Call / work with Polycom in India and check for RMA options.
There is nothing I can do from here or give you any prices.
Best Regards
