Hi!
Looks like the SNOM phone has problems with the DNS resolving. If you
compare the log of the phone, 5 minutes after the initial REGISTER. In
case of sip.de.domain.cc everything is fine. In case of
siptest1.domain.cc, the phone does DNS lookups, but does not reREGISTER.
Thus, I guess there is a problem with snom/DNS or with your DNS
configuration. Try to swap the domains for ser and openser.
btw: are these the real domains (sip.de.domain.cc) or did you changed
the logfiles? I can't find any SRV records for those domains.

Hello Klaus!
Thanks for your reply, you have triggered some new ideas. of course i
should have thought about checking back if any packets are received by the
openser host after the line is dead but i thought if it still works with
ser, it should work with openser too(and i still have no problems with a
second line registered at [EMAIL PROTECTED] while the registration at
[EMAIL PROTECTED] is lost).
ok, the result of the ngrep was that no packets appear on the openser-host
when i try to call from the (dead) line. i've made some tracing both on
the snom and the ser/openser-host as you suggested.
To my surprise, the snom seems to be the device that doesn't behave as
expected - it doesn't re-register on the openser-configuration!
I have made the attached traces in this way:
First i've set the account-details on the snom with
[EMAIL PROTECTED],then rebooted the phone and started the trace on
the siprouter-host on port 5060(ser), then changed the configuration to
[EMAIL PROTECTED], rebooted the phone and made the second trace on
port 5061(openser). In both cases i didn't touch the phone or make any
calls after the reboot to get a pure registration-trace.
When i use the account [EMAIL PROTECTED], the snom registers once
and doesn't try to re-register anymore.
With the account [EMAIL PROTECTED], the snom re-registers every 5
minutes, not the expected 10 minutes, but at least it does re-register.
When switching the account-details, i didn't do anything but changing the
login-details(username, password, registrar-url), the rest of the
configuration has not been touched.
The phone-firmware is 3.60w.
There doesn't seem to be a difference between the siplogs, at least i
can't see it. i'm really puzzled right now... 8-|
I've attached the siptrace from the ser/openser-host:
SER_host_siptrace.txt/OPENSER_host_siptrace.txt
the syslog from snom190:
SER_snom190_log.txt/OPENSER_snom190_log.txt
and the siptrace from snom190:
SER_snom_siptrace.txt/OPENSER_snom190_siptrace.txt
I have tried this several times now, changing the configuration and
rebooting, same results everytime. on SER it's reregistering exactly every
5 minutes, on OPENSER it isn't.
I hope all this information is not too much and you have the time to sniff
through.
thanks!
christian
p.s.:i've also thought about a error in the srv-records on my nameservers,
but they look exactly the same for all sub-domains, the only difference is
the port change from 5060 to 5061...

Hi Christian!
The more interesting part would be the SIP signaling between the SNOM
and the proxy. If registration is lost, that means that:
- SNOM stops sending REGISTER or
- SNOM still sends REGISTER but they are not accepted by openser Please
set exires back to 10min and watch the SIP signaling:
- using "ngrep -t -W byline port 5060" on the proxy
- using the logging feature of the snom phone
Please post this logs.

Hello!
I've been running my experimental(production in the near future)
environment with ser and a mysql-db for some months now but want to switch
to postgres and openser soon. i'm using a very simple routing as i
didn't
have the time to dig deeper into the ser-routing-language.
i've already adapted my current config-file to openser and the routing
works as expected. still, there is one major problem i could not cope with
yet: Expiry.
i'm using a snom 190 and had the "proposed expiry"
set to 10min with ser, without any registration-problems or
registration-loss.
with openser with the same settings on the snom i loose my
registration
within a few minutes after phone-reboot, when setting "proposed
expiry" to
1min on the snom it works without problems endlessly - but setting
this
generally to 1min on all the phones that will register at openser
doesn't
seem to be a good idea and i guess there are other ways.
I've tried to force it with the modparams min_expire 100, max_expire
1800
and default_expire 600
but the result is still the same, calls are possible after rebooting
the
phone, but after some minutes(below 10min), i loose registration. I
had
similar problems due to a firewall closing the connection, but that
occured when i had set a 60min expiry on the snom(with ser), the 10min
timeout works fine with the same snom 190 and ser.
I've searched a lot for
expiry-problems but only found the modparams above that could be
responsible for this.
Sorry if my explanations sound simple and untechnical,
but i'm pretty unexperienced with ser/openser yet so i try to explain
it
the way i understand it, simple ;-)
i've attached my config-files, both ser and openser:
21X.XXX.XXX.100 is the host running ser(port 5060) and openser(port
5061)
21X.XXX.XXX.101 is asterisk1
21X.XXX.XXX.102 is asterisk2(asterisk2.de.domain.cc)
i'm registering my phones at openser with the domain
siptest1.domain.cc, the
second domain sip2.de.domain.cc is a test for a multidomain setup but
doesn't work yet(i can't
use the domain-column provided by the db since i need two different
origination domains in asterisk's sip.conf to seperate the calls - maybe
not the best approach...)
p.s.:
a second question regarding the multidomain - i can't register with
sip2.de.domain.cc - i guess there's something wrong with my regexp
"if (uri=~"^sip:(.+@)?((sip2\.)?(de\.)?domain\.cc)([:;\?].*)?$") {"
someone having mercy and tell me what is wrong with my syntax(or maybe
a
link to a descriptive documentation - ser admin guide was not enough
for
me)?
