[Serusers] DNS SRV,t_replicate,backup server and GS phones

[Zen Kato]

Hi,

http://www.voip-info.org/wiki/view/SRV+implementations says
bad clients:

- Grandstream GXP-2000, 1.0.1.12
uses first SRV, no failover, ignores ICMP

- Grandstream BR-102, 1.0.6.7
uses first SRV, no failover, ignores ICMP

GXP2000(1.0.1.9) and BT101(1.0.7.11) still use first SRV,no failover.

So workaround is(if UAs are set 5min REGISTER intervals):

stop ser1                stop ser2
    |                       |
    V                       V
....|<-- 5 min-->|<--sip2-->|<-- 5min -->|<--sip1--.....->
    |service stop|service   |service stop|service 
           A     |continue  |     B      |continue

During service stop time A and B, users can not make calls.

Is there another way to reduce service time time?

Regards,
