[Q] [B]server not connected[/B]

Hi,
I flashed several ROMs and right now I'm on the Eybees JB release.
When I use voice command to dial a number it will work fine one ore two times but then it it tells me that the server is not connected.
Switching off wifi and turning it on again solves the problem for again one ore two times but than same problem.

Experienced that on some other ROM as well but for example not on RocketRom 12.

What can I do, thanks for your help
