If the load is the same on both, it could be bad RAM or something wrong on the motherboard.

[Invictus]

all servers are vps with same configuration

These kind of issues are common problems with virtual environment. It's never recommended to use VPS and even become worse to debug

[Invictus]

I have another problem; when I directly make a call from webphone if call is answered immediately there isn't any problem but if call is answered after 6-7 seconds there is no audio on both side.
