asterisk users - Jul 2006 - Extensions dialing but fails on pickup

Hi,

Ive installed freePBX and Asterisk and all is working well. Ive created 2
extensions using freePBX ie 8888 and 1235 all SIP Phones. When i use 1235
ext to call 8888, it rings OK but when i pickup ext 8888, the call fails
with an error ( i.e an error has occurred) and i get a busy tone.

Did i miss out something in the configs?
