I have noticed that we are facing multiple issues with VOIP devices on both of the sites with ASA, is there any recommanded voip settings for ASA.

It depends on the problems.

If you are facing voice quality issues then QoS might help. Here is an example http://supportforums.cisco.com/docs/DOC-1230

If you are facing call set up issues then sip or h323 inspection are worth trying.

These are two basic things I would start with.

I hope it helps.
