[resolved] SMS() in 1.4 automatically hangs up?

The same dial plan

exten => s,n,SMS(myqueue) exten => s,n,NoOp(sms sent)

In 1.2, dial plan proceeds to the next priority after SMS(). But in 1.4, Asterisk immediately abandons the channel after successful SMS transmission and quits the dial plan. Anyone noticing this? Any reason?

I’m using 1.4.0 on Linux 2.4.18-19.7.x.

Partially resolved. It may have something to do with the 1.2 box I was testing against. But the same test between 1.2 boxes does not have this problem.
