it was a matter of clocking!<br>
All i had to do was make the Alcatel's side bri to be master (network
side) and i configured my BRIs as slave (user side) with and the
problem was immediately solved!!<br>
It was very difficult for the Alcatel because they had no one to do it.
But when the company hired a tech guy supporting alcalel he found the
solution and it worked!!<br>
I don't know how you can configure Alcatel to be Network side but here
is what i have for my cisco:<br>

<font color="#000000"><b>Is there any possible idea why is this
happening? In monday, i have a rendez-vous with the man who configured
alcatel. Is there anything i can do till then?<br>
Why the negotiation of multiple frame begins? Isn't multiple frame
established since is point-to-point?<br>
Since it gets established, why the router tries again?<br>
And why sometimes alcatel does not reply?<br>
I think i am going mad. That's why i don't like qsig and old PBXs
