Bandwidth.com - redundancy / backup IP

[Joe Morrison]

Bandwidith.com SIP gives us two IP's for failover/redundancy.

Anyone have success in setting up a 2nd SIP trunk?

I tried setting up a 2nd exactly the same as the first except with the IP
When implemented, inbound calls stop coming in. Once the 2nd Trunk is removed everything works normally again.

Hello @Joe Morrison

Are you using the 3CX provided template to setup your trunks? IF so check if the Call source identification is enabled under the Inbound parameters of the trunk. If you are using the same DID's in both trunks you may need to enable the "Use both "Call Source Identification" rules and "Caller Number/Name -> CalledNum" field mappings (Note: Disables catch all routing capability)" option.
