Is there a reason you have to Answer() before you call Dial()?  If you just 
call DIAL when calls come in, the call will be answered when Sip/pfriedel 
picks up.  This should clear up the ring tone problem.

Do you hear this static when dialing out to PSTN as well? 
Check /proc/interrupts to make sure wcfxs has it's own IRQ.

If it does have it's own IRQ, then it may the same problem that many people 
have had with these cards (intermittent STATIC noise).  And I've yet to 
see/find a solution.  
Workaround is to unload/reload wcfxs... best to call Digium and let them know 
if this is the case.

I have a TDM400P card all installed, and I can call out from a sip phone, but 
when I call from the PSTN into the asterisk machine, as soon as the Answer() 
gets called, the dial tone changes and is sounds like there is a lot of  
static on the line.

Below is the part of the dial plan for answering the call.


exten => s,1,Wait,1
exten => s,2,Answer
exten => s,3,Dial(Sip/pfriedel,20,tT)


Thanks

Let the call be answered by the called user, rather than in advance
by your dialplan.

Remove the Wait and Answer commands (you had them in the wrong order
anyway) and renumber "s,3,Dial(...)" to "s,1,Dial(...)".
