Voice calls going blank

Hi,

I am using CCM 4.1.3. and E1 circuits connected to NM-HDV2 module in Cisco 3745 router.

Sometimes I am facing the issue that voice calls are going blank in between. Nothing can be heard in between but there is no call disconnection.Manual call needs to be cutted down and then its working.

Required help soon.

Thanks in advance.
