New subject: [Serusers] Aliasing problem

15 Jul 2004

Ok this must be where I am confused... the only alias I have created is
"1000" and is mapped to sip:admin@sip.dev.inmarsat.com

If I do a "serctl show alias admin" I get what I pasted below... I would
have expected to see the newly created "1000" alias... However, doing a
"serctl show alias 1000" does list admin.. as below

[root@sip log]# serctl alias show 1000
<sip:admin@sip.dev.inmarsat.com>;q=1.00;expires=31532649
<sip:test1@161.30.211.131:5060>;q=0.00;expires=399

But it's also showing test1?!?!? WHY! Lol! I have never created any
aliases with test1.  Similarly:

[root@sip dave]# serctl alias show test1
<sip:admin@<ip1>:5060>;q=0.00;expires=2621

Now as far as I know, that last command should have returned nothing, as
I have never created any aliases for test1.  

Also, I know that serweb creates aliases automatically - but it is set
to create numerical aliases.  Besides, I am not using serweb to create
users, so that's just something else.

Are all the registering UAs messing up the aliases somehow?  This is
becoming very frustrating!

SER does not create aliases automatically (only serweb does so when
creating a new user account). Only the content of location table gets
updated automatically from REGISTER messages.

If the aliases are not correct then you can remove them using serctl and
create new ones.

  Hey Jan,

 I guessed this! Which is why I am confused.  I have not created these
 aliases... all I have done is registered three different UAs with three
...
  different usernames (admin, test1, test2).  This is
why I don't
 understand why there are all showing up. I think this may be why the
 extensions have stopped ringing correctly, but I don't know why it has
 happened.

 Any suggestions? Tests?  Anything to do with net configuration? SER
 believing it is the same user agent registering each time?  

 Once any, many thanks for all the support being shown here.

 Dave

 aliases are not recursive, in other words you cannot do something like
 this: alias1->alias2->alias3, SER would only translate alias1 into
 alias2 and then forward the request there.

 If you create several aliases for a single user (alias1->user1,
 alias1->user2, alias1->user3) then all of them should ring because SER
 will fork the INVITE.

time ago, see:
