Many SIP Providers send calls from another IP when sending inbound calls. Please vote to add multiple IP addresses as a source accepted. Currently 3CX only accepts calls from one IP. This results in additional SIP trunks having to be created and duplicating DID rules for each sip trunk. I work with a provider that sends calls from 5 IP's. It would be nice for outages to get calls from all 5 of their endpoints.
