<div dir="ltr">Hi,<br><br>I'm planning to deploy SIP hardphones in a serverless location.<br>Phones would be connected to 2 different Asterisk servers, one backing up the other.<br><br>I would like to offer resilience and I'm wondering about the best way to do it.<br>
<br>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.<br><br>I'm wondering if should use DNS, phone multi-registration feature, or a combination of DNS and phone multi-registration feature, to implement resilience.<br>
Your opinion ?<br><br>Cheers<br></div>
