That is actually a GSM setting used to set suspend and resume for data connections when receiving a call. - If set wrong on a CMDA phone you wont be able to answer calls. It should be #777. If you use 'Advanced config' that came with the rom, it might change the setting on you.
Here is Microsoft's description -
