[JDEV] AIM Gateway Register Error

[Vimalathithan Krishnan]

On sending following XML to register AIM user,   <iq to='aim.lindev05.flytechnology.com' type='set' from='[EMAIL PROTECTED]/totalport'><query xmlns='jabber:iq:register'><password>password</password><username>u2229</username></query></iq>   I’m getting below mentioned error message.   <iq to='[EMAIL PROTECTED]/totalport' type='error' from='aim.lindev05.flytechnology.com'><query xmlns='jabber:iq:register'><password>password</password><username>u2229</username></query><error code='406'>Not Acceptable</error></iq>   But the same XML input with appropriate username and password works fine for Yahoo & MSN.   What is going wrong here?   -Vimal
