Nobody responded, but I was able to resolve this issue the way I wanted.
In my extensions.conf I put the following:
[callback-dialtone-auth]
exten => s,1,answer()
exten => s,n,authenticate(5678)
exten => s,n,Read(fwd_callback_to)
exten => s,n,NoOP(${fwd_callback_to})
exten => s,n,Dial(SIP/[EMAIL PROTECTED])
Now when I receive a callback, I enter password and after entering
password I enter the phone number ending with # I wish to call and it
gets passed to callcentric SIP and all works great.
I posted the solution just in case someone else will have similar issues.
