Everything seems Ok, but here begins the problems.
The contact is malformed -- this bug has already been fixed by Bogdan.
If I go to the command line and type:
# serctl ul show gstream1
I get:
404 Username gstream1(a)ipcontact.com.uy in table location not found
But if I type:
# serctl ul show
Among many other lines I get:
.....
...Record(0x402f46e0)...

aor : 'gstream1(a)200.59.203.76'

It seems to my like ser is not matching the domain part properly.
Yes, unstable branch is work in progress, 200.59.203.76 means a
different domain to ser than ipcontact.com.uy. This is not correct and
causes troubles sometimes. A quick solution is to use hostname in
the domain part.
On the other side, the record in the mysql location
table is:
username | domain | contact | expires
| q | ....
gstream1(a)200.59.203.76 | | sip:gstream1@200.59.203.75:61503 | 2004-05-04
17:20:32 | -1082130.38|...
As you see 'domain' field is empty. Could be this the problem?
That's because use_domain parameters are set to 0, set it to 1.
Anyway If I register from Kphone (user luis) running
in the same machine as
SER, 'domain' is empty again
luis(a)ipcontact.com.uy |
|sip:luis@200.59.203.76:5062;transport=udp|2004-05-04
16:57:46|1148846.12|...
and
# serctl url show luis
fails too, however I'am able to call this user "luis(a)ipcontact.com.uy" but
not "gstream1(a)ipcontact.com.uy"m.uy".
The problem here seems to be gstream1 is registered using the ser server's
IP number and not the domain "ipcontact.com.uy", but shouldn't be this
handled automagicaly by SER.
Yes, it should, it's work in progress.
