[Asterisk-Users] DNS SRV supported phones

[Anish Basu]

According to our tests, the Polycom 301 and 501 both failover instantly
using DNS SRV records.  The grandstream BT101 and GXP-2000 also failover
using DNS SRV, but only upon re-registration.  This requires that you set
the registration interval to a very small value.  Has anyone gotten the
sipura phones to use DNS SRV?  They are supposed to support it, but I could
not find documentation about it anywhere.

Have you found any information yet about this?  I am looking for good and
affordable phones that can use DNS myself, but not for failover, simply for
ease of use by some non-computer savvy family members.  So far, I am afraid
I'm going to be limited to USB/software phones.  I would greatly appreciate
any advice you can share.  Thanks!

Hi,

I am looking to use DNS SRV records for load balancing and failover across
multiple Asterisk servers.  The Asterisk servers share the exact same 
configuration via mySQL replication.  I would like to know which particular
SIP phones support DNS SRV and would like to hear of any success stories.
Many SIP phones claim to support DNS SRV, yet there is usually very little 
documentation on how to configure it to do so.  Any input is appreciated.
Thanx in advance.
