  ^^^^^^ that should be fxsks (might also try fxsks=3 since your only 
         module is #3. I don't remember how these are numbered for sure.
         Don't forget to run 'ztcfg -vv' after the modprobes. That should
         tell you which channel the fxo module is on.

          ^^^^^^^ I strongly suggest changing this to some other keyword
                  as it appears that you're using "default" as the sip
                  context as well, and that's going to give you fits.
                  Try something like context=inbound-home or whatever.

I assume the following is really extensions.conf (even though you didn't
mention it).

Now you need to add this for inbound TDM calls (see above):
[inbound-home]
exten => s,1,Dial(SIP/8500},15) ; extn to ring when inbound call arrives.
exten => s,103,Congestion

Interrupts look fine with wctdm card on its own.
