IPO SE redundant with Sip Trunk

[forcetranquille]

Hello,

Quick question, we have an IPO Server Edition Primary Server on a Data Center A and a Secondary Server on a Data Center B.
There is one SIP trunk on each of the Data Center. There are 100 SIP Trunks licences with no SBC.

Is it possible to make it redundant with the following architecture ? SIP Trunk A registered on Primary server and SIP Trunk B registered on Secondary server. If SIP Trunk A or Primary server failed, incoming calls are routed on SIP Trunk B with Secondary server.

Thank you
BR

Are the SIP trunks with the same provider ?
Our provider does this for us.

Site A goes down.
Phones fallback to site B.
provider switches inbound traffic to Site B.

Yeah... I like that.

You need overflow ARS that routes calls to the other server of one trunk goes down.

Inbound should be easy.
