Unable to Pick Up A Call During Data Session

[Biker1]

While I am on a Data Session, and an incoming call comes in, I slide to answer but it does not connect the call. The call keeps singing until voice mail picks up.
I am using the native slide to answer/ignore.
This issue just started to occur.
Any ideas are appreciated.
Also, whenever I connect to a Data Session, I get this pop up that "says connecting to data using cellular #777"
Real annoying and just started happening. I don't know if both issues are related.
Update :
I read that if you go to registry settings >
HKLM
Comm
ConnMgr
Planner
Settings
Suspend/Resume
and if the value is not #777, then change it to #777
Mine says ~GPRS!
I will not make any changes until someone confirms that I should.
I recently changed the battery polling time but I don't think that is the cause.
I have AdvanceConfig and Diamond Tweak downloaded, so from what I read, one or the other changes a registry setting which causes the issue I am having.
I'll make the change and see what happens.

I made the #777 change and am now able to pck up incoming calls again
As for the pop up window I described earlier, that seems to have stopped popping up also.

this happend to me so i called sprints tec line
they told me to put like a 9 digit number
then it took me to like a built in regestry editor
and i forgot what he said to do but i do
remember he told me to change 1 to 0
theres also some tweaks you to apply
i recommend u getting pocket shield and
use the default dialer pad not htc

My phone did this too on the mightygroove rom. I just hit the send/phone button to pick the call up instead. But, I did this fix as well.
