Toll Free calls not working on SPA1001 Line2

[beaver]

I opened my IPKall and my voxalot Jan. 2010. I had set voxalot on my SPA1001 Line1 using port 5060. It was working fine (inbound 360-xxx-xxxx & outbound toll free calls).

Today, I moved this setting from Line1 to Line2 using port#5061 because I need to restore my previous voip on Line1 using port 5060.
My inbound calls on Line2 (360-xxx-xxxxx) runs good still. Echo test on Line2 also seems working (# *600).
But it's found that toll free calls couldn't go through any more. Either dial 8xx... or 1.8xxx. Most time, I heard nothing, some times I heard "yes". It ended up to a busy tone.

I did search in voxalot forum, there were about ten threads discussing voxalot line2. My Line2 config sounds ok (as said, # *600 echo test passed and inbound works).
I am thinking it's a dial plan issue, but couldn't figure it out. I am using
([*#x][*x].)

Anyone can help?

Thanks,
