Hi,
When we have a situation in which a PC changes IP addresses (like on
dialup), we end up with multiple registrations (see below). Is it possible
to configure SER so that it only has the latest registration?
[root@maui ser]# serctl ul show rvilla
<sip:rvilla@200.58.193.72:5060;transport=udp>;q=0.00;expires=2773
<sip:rvilla@200.58.203.236:5060;transport=udp>;q=0.00;expires=3194
<sip:rvilla@200.58.203.61:5060;transport=udp>;q=0.00;expires=3544
On a related note, the registrar README says:
"Name: lookup
Params: table - Name of table that should be used for the lookup
Desc: The functions extracts username from Request-URI and tries to find all
contacts
for the username in usrloc. If there are no such contacts, -1 will be
returned.
If there are such contacts, Request-URI will be overwritten with the contact
that
has the highest q value and optionally the rest will be appended to the
message
(depending on append_branches parameter value)."
....but as you can see all 3 contacts have the same "q value" (whatever that
stands for).
How does one resolve such an issue?
Thanks,
Ricardo

Hello,
registrar has "append_branches" parameter, if set to 0 (default is 1)
then registrar will use only contact with the highest q value. I created
a patch for 0.8.10 which orders contacts according to the modification
time so that only the most recently update contact will be used. What
version of ser do you use ?
regards, Jan.

it might be possible to configure ser that way, but the problem may also
be with you or your sip ua.
you should namely exit your sip ua before you logout your dialup or
whatever internet access. at exit the ua should send a register request
with header field:
Expires: 0
and that will remove the registration from ser. if your ua doesn't send
that kind of register request at exit, then there is a bug in it, which
should be fixed rather than removing forking capability from your ser.

Hi Jan,
I use 0.8.10, so from what you are saying, SER will only use the bottom
contact in my example?
[root@maui ser]# serctl ul show rvilla
<sip:rvilla@200.58.193.72:5060;transport=udp>;q=0.00;expires=2773
<sip:rvilla@200.58.203.236:5060;transport=udp>;q=0.00;expires=3194
<sip:rvilla@200.58.203.61:5060;transport=udp>;q=0.00;expires=3544
And regarding the "q value", what is it? And why are they all the same?
Since they are all the same, I fail to miss the point: "then registrar will
use only contact with the highest q value".
And if if were to add the "append_branches" in the ser.cfg file, where
exactly would I put it?
Thanks,
Ricardo

Hi Juha,
You are absolutely right about "exiting" the UA agent (our UA agent works
fine). But not everybody in the network is going to go through the menu and
click "log out" every time. Some people will close it, or some people might
drop their dial-up connection and redial again right away.
I am just trying to eliminate this scenario as a potential problem.

Ricardo

even if you close the UA window, it should still unregister. droping of
connection wihtout the user doing so is of course another thing that
very little can be done about.

but at the same time you are removing an extremely valuable feature of

as Juha allready stated normaly the UA should unregister.
And to your example i would say this is not normal. If a user contacts every 5
minutes from another IP he should set the expires value in its UA to value so
that nothing goes wrong. I mean in reality i would not expect that some
registers every 5 minutes from another IP. But if the user do it this way he
should set the Expires value maybe to 7 minutes.
And the last choice would be that the UA unregister all previous registered
contacts (for example on startup) and registers its current contact after
this. But this should be an option for user who know what they are doing (for
example an extra button which ask twice before unregister everything).
And at last: the q value gives the user the chance to configure in which
sequence a proxy with forking should try to reach the user at the different
contacts. So the user can configure that the proxy should first try contact a
and after this try contact b because of its higher or lower (i'm currently do
not know how the contacts will be sorted) q value.

Hi Nils,
I agree that my example is not normal behaviour. But out of 100 users, I am
sure, at least one would experience multiple registrations due to dropped
dial-up calls. And modifying the UA agent as per your suggestions is really
beyond my control.
Thanks,
Ricardo

I agree with Juha. In my opinion possibility to register and use more
than one contact is very nice feature of SIP and it shouldn't be restricted
this way.
It is also possible that user agents will register more than one
contacts transparently, they may use different port numbers for presence
and instant messaging (SUBSCRIBE,NOTIFY,MESSAGE) and different port
number for voice (INVITE, ACK, BYE). Restricting ser to just one contact
will prohibit such user agents because our registrar doesn't support
callee preferencies yet. On the other hand right now I am not aware of
any user agents using multiple ports this way.
Also user agents capabable of simultaneous use of TCP and UDP might want
to register 2 contacts, one for UDP and one for TCP transport.
If I understood your email correctly, the only problem with unregistered
user agents when IP address changes is that another user agent (which
was assigned IP address of the previously unregistered user agent) will
receive calls not targeted to him. Something like this:
1) UA1 with IP1 registers
2) hang up, UA1 is still registered with IP1
3) another user dials in, gets previsously freed IP1 and starts UA2
4) UA2 registers (with different address of record)
5) UA3 invites UA1 (which is offline already) but the INVITE will be
sent to UA2 (which has now IP1)
I don't know if there is any time window in which a previsously assigned
IP address must not be reassigned, but I assume no.
Such a situation cannot be completely avoided, but the probability that
something like this will happen can be significantly decreased by using
reasonably short expires intervals. Morover I could extend registrar to
either: 1) refuse contacts with too long expires parameter
2) force shorter expires value if the value provided by user
agent is too long.
Shorter expires value will, of course, increase traffic.
What do you think ? Maybe limited expires value could solve your
problem ?
In regards to q parameter: q is preference of contacts (see RFC3261).
This parameter is provided by user agents when registering contacts and
can be assigned value from 0.00 to 1.00, where 0 means the lowest and 1
the highest priority among contacts registered for a single address of
record.

Jan,
I agree hat the feature is very useful. However, from
an ISPs point of view, it may be desireable to restrict it.
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.
Is it possible to call a deregistration function when the register
happens?
Perhaps a delete(id) followed by the save(id). In this way, it would be
guaranteed to only have one registration by a single customer. E.g.:
If(method=="REGISTER")
{
if(!delete("location"))
{
log("ID was not already registered, ignoring");
};
if(!save("location"))
{
sl_reply_error();
};
};

Hi Jan,
Regarding the "q" parameter, thank you for the explanation.
Regarding my "potential" problem, I was thinking that if I could use the
"serctl ul rm" command:
serctl ul rm <username> ................... delete user's UsrLoc entries
to delete the oldest duplicate contact, it would be great since I could
write a Perl script for it. But the "serctl ul rm" command does not do
anything if we append the ipaddress to the username.
[root@maui sip]# serctl ul show pperez
<sip:pperez@192.168.0.111:5060;transport=udp>;q=0.00;expires=2335
[root@maui sip]# serctl ul rm pperez(a)192.168.0.111
200 user (location, pperez(a)192.168.0.111) deleted
[root@maui sip]# serctl ul show pperez
<sip:pperez@192.168.0.111:5060;transport=udp>;q=0.00;expires=2322
[root@maui sip]#
I think this would be better than modifying the registrar and affect all
other SER users.
Thanks,
Ricardo

Hello Ricardo,
enclosed find a patch that modifies the registrar so it will be possible
to use just one contact. You will have to use
modparam("registrar", "append_branches", 0) in your script and after
that only the most recently updated/created contact will be used (even if
there are many of them).
Note: if you don't use the modparam, the registrar will still use all
registered contacts.
This should do exactly what you are asking for.
Put the patch in parent directory of ser-0.8.10 and apply it using
patch -p0 < reg-ordering.patch

However, from an ISP point of view I want to charge customers

someone has two POP email clients reading the same POP

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?

Hello Greg,
thanks for the clarification.
Anyway, if these restrictions cannot be made it
doesn't matter to
me too much. However, if it was possible for me to restrict the

to just one SIP phone connection I would definitely do so. I think it
Is a good idea...but that is just my opinion :-)
Just apply the patch and set the parameter as described in the email

serctl ul rm <username> ................... delete user's UsrLoc entries
to delete the oldest duplicate contact, it would be great since I could
write a Perl script for it. But the "serctl ul rm" command does not do
anything if we append the ipaddress to the username.
[root@maui sip]# serctl ul show pperez
<sip:pperez@192.168.0.111:5060;transport=udp>;q=0.00;expires=2335
[root@maui sip]# serctl ul rm pperez(a)192.168.0.111
200 user (location, pperez(a)192.168.0.111) deleted
[root@maui sip]# serctl ul show pperez
<sip:pperez@192.168.0.111:5060;transport=udp>;q=0.00;expires=2322
[root@maui sip]#
I think this would be better than modifying the registrar and affect all
other SER users.
Thanks,
Ricardo

ul rm removes all contacts for an aor.
[jiri@fox jiri]$ sc ul show jiri
<sip:130.129.141.109:8390>;q=0.00;expires=722
[jiri@fox jiri]$ sc ul rm jiri
200 user (location, jiri) deleted
[jiri@fox jiri]$ sc ul show jiri
404 No registered contacts found
[jiri@fox jiri]$
Through a mistake in usrloc'c fifo, non-existent aors are okayed.
[jiri@fox user_interface]$ sc ul rm jiri(a)bla.com
200 user (location, jiri(a)bla.com) deleted
You wish to use ul_rm_contact to remove a particular contact.
It takes table name, user name and the contact as parameter.

registrar and affect all
