Can you tell me more ?

Hello,
Ok SRV records point to proxy sip server but if

one is down before or during connection !!!
During a connection doesn't matter in my environment. I am running SER in a stateless mode. Once the call is setup media flows between endpoints and the proxy is out of the connection. I am not using NAT either.

How [?] can it provide H-A (heartbeat soft) between ser boxes.
Neither the SRV or VRRP can provide a heartbeat between SER boxes. You'd need an application running on the SER boxes to do that. I rely upon t_replicate to update the backup during registration, I use NAGIOS to monitor SER to know when a server of applications on that server have failed and I use an SRV record defined in each phone to identify the proxy. This way the phone will failover on it's own during call setup. Of course this doesn't help during a call but as I said I am running SER in a stateless mode so the proxy "steps out" once the call is setup.
If one of these sip proxy failed during a call can
we
redirect the call to the other proxy ?
I'm not sure how you would accomplish this.

Sorry. I don't do diagrams :-) Which piece of this explanation is unclear?

VRRP for layer 3. H-A woud depend upon your availability requirements. In our case we use an SRV record to identify multiple proxy servers each with their own priority and weight. Phones
register
using the SRV name as the proxy address. Each proxy uses
t_replicate
to
replicate registration data. So far this works for us.

Ok so vrrp for layer 2/3 but which solution for
H-A
?
