Oliver,
We use DNS SRV records combined with short TTLs
How short ?
to provide failover.
Thankfully, we have only used it when moving phones from one server to
another in preparation for upgrades, but it worked like a champ then.
I was first inclined to use DNS instead of phone feature for several
reasons.
But I'm curious to compare those reasons with others.
Your experience proves using DNS makes sense :
it gives capability to fall back to main or backup proxy at will,
it doesn't hide strange phones behaviours,
...

Hi,
I'm planning to deploy SIP hardphones in a serverless location.
Phones would be connected to 2 different Asterisk servers, one backing
up the other.
I would like to offer resilience and I'm wondering about the best way
to do it.
Phones themselves can register to a backup SIP proxy if first proxy
fails but, AFAIK, can't fall back to main server from backup server
when main server recovers.
I'm wondering if should use DNS, phone multi-registration feature, or
a combination of DNS and phone multi-registration feature, to
implement resilience.
Your opinion ?
Cheers
