thanks for the info, as I have no ISP experience, it is hard for me to
understand why such restriction is benefical for ISPs. Some comments are
inline, I would appreciate if you could give me more hints. I've sent a
patch that implements the restriction, but honestly I still don't understand 
motivation for the restriction.

  Why is it desirable ? Why, for example, your costumers are not allowed
  to have MS Messenger for IM&P and some kind of SIP hardphone for voice
  sessions ?

  I think that dialup account is something completely different. I
  understand that ISPs want to restrict costumers to just one
  connection, but on top of the single connection you can have several
  simultaneous SIP sessions running. You are limited by the available
  bandwith only. I think that you don't restrict users to just one FTP 
  connection at a time, do you ? Why do you want to restrict SIP this way ?

  No, there is no such function, see the patch that I sent a while ago.

   regards, Jan.
