Hi,
this is not a technical question regarding OpenSER, but more of req for
information.
I'm using Cisco phones and gateways and have implemented DNS SRV
redundancy.
However, I have never seen a SIP phone that really works with DNS SRV
redundancy, except from Cisco. (which actually works as a charm)
Does anyone know other phones that can use dns srv for redundancy?
At least Cisco tries the next DNS SRV entry if it receives a port
unreachable from the highest priority proxy...

Hi Helge!
According to my tests, also SNOM can do SRV based failover.
I've published my test results at:
http://www.voip-info.org/wiki/view/SRV+implementations
Please add your test results to this.

Hi,
I've started to add some more information to voip-info.
I'm still waiting for response from Grandstream and others on their
support (or future support) for DNS SRV.

Hi,
I posted on [serusers] regarding DNS SRV,t_replicate,backup server and
GS phones.
My test resut of BT101(1.0.7.11-newest) and GXP2000(1.0.1.9) was
no good.
My question is eventhough we set up DNS SRV on server side, if sip
clients does not suppot DNS SRV, do we have a risk of (5+5)minutes
out of service time when we set up 5 minutes REGISTER intervals?
If UA have multiple REGISTERs outgoing lines such as GXP2000,
we could set up Line1 for sip1&sip2(DNS SRV) Line2 for sip3 server.
In this case if line1 does not work, the user can use Line2.
Xlite can register 3 sip servers, but only default sip proxy can
use as outgoing line, so the Xlite users have (5+5)minutes out of
service risk.
Does Cisco 7960 work perfectly on DNS SRV?

Zen

Hello,
there are different SIP stack implementations. Some clients do SRV
lookup only at first registration time, or only when they register.
Ideally, they should do it for each request sent out. As you figured
out, the best option is to test it before providing such device to your
customers. The idea with wiki is good, so people doing such tests can
share the results.
I do not get the question regarding the out of service interval when the
client does not support srv. How you computed the 5+5 interval?
Cheers,
Daniel

Hello Zen,
We sell GS in the Netherlands on our website www.voipwereld.nl and
therefore we tested DNS SRV on a number of different GS models. DNS SRV
works with Grandstream HT 488/496 boxes perfectly. These boxes
automatically detect if one SIP server is down and move over to the next
one.
DNS SRV is also implemented in GXP-2000 but appears to do a DNS query
once at start up instead of before every call.
This is not perfect and should be done before every call or REGISTER
without need for a reset. This will be fixed next firmware release of
the GXP-2000 according to GS.
Best regards
Paul van Schagen

Does anyone know other phones that can use dns srv for redundancy?
At least Cisco tries the next DNS SRV entry if it receives a port
unreachable from the highest priority proxy...
