Vicibox 8.0.1
Asterisk 11.25.1-vici

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

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

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.
