Greg,
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.

I agree with you, it is desirable to have this functionality.
However, from an ISP point of view I want to charge customers
for it! 2 SIP devices will take twice the support as one SIP
device. I can't being to tell you how many support calls we get when
someone has two POP email clients reading the same POP
server. An ISP sells service. If the customer want's the 'multiple
phones share the same SIP proxy account' service then it is appropriate
to charge for it, because we have to support it!
Also, 911 is an issue. If we are doing emergency delivery for
a 911 call we need to know that it comes from the phone at
the location that needs the help.
I'm sure there are other reasons. Certainly it doesn't hurt anything to
provide the ability to limit to 1 registrant, no matter what the reason?
Jan,
I agree hat the feature is very useful. However, from
an ISPs point of view, it may be desireable to restrict it.
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 ?
Most of our
customers are only permitted one sip phone
connection. Same sort of thing with dialup accounts, it is
possible for
radius to authenticate multiple connections, but,
an ISP may only
wish to allow one dialup connection...this was difficult to do with
radius for quite a long time. I know I would like to restrict my
customers to just one connection.
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 ? Is it possible to call a deregistration function
when the register
happens?
No, there is no such function, see the patch that I sent a
while ago.
regards, Jan.
