Zap - skip first ring

I almost have ZAP working for my distinctive ring situation, but I believe i need to skip the first ring.

ZAP is picking up the ring pattern on the first ring and going directly to the appropriat context. I want it to ignore that first ring, and act on the second ring.

Here is what I have so far:

In zapata.conf:

usedistinctiveringdetection=yes
context=from-custom-123456

dring1=0,0,0
dring1context=from-custom-234567
channel => 2

In extensions_custom.conf

[from-custom-123456]
exten => s,1,Goto(ext-did,123456,1)

[from-custom-234567]
exten => s,1,Goto(ext-did,234567,1)

I only want to check the ring pattern for distinctive ring on the second ring.
