Channel reported in use

Hi,
I’m using asterisk 1.4.10.1 with fedora 7. Trying to use the TE210p card working on it.

When i’m trying to make out going calls getting,
"-- Channel 0/18, span 2 got hangup, cause 44
– Forcing restart of channel 0/18 on span 2 since channel reported in use
"
I have done the pri debug on span 2. Here is the Debug result

– Executing [0011@test_me:1] Dial(“SIP/1234-b7e04ed0”, “Zap/g2/001188027563117”) in new stack
