All partners and customers using IP-based SIP carriers can now use Hosted by 3CX, our fully managed hosted solution. We’ve enabled over 100 IP-based providers, available with their templates inside Hosted by 3CX. This makes the transition to our hosting service even easier than before!
Why registration-based is the preferred option
Registration-based trunks with no IP fixation remain the preferred option in a hosted environment. This is because in certain cases the Public IP of your Hosted by 3CX can change unexpectedly. Although this is not a regular occurrence, if this happens, you will temporarily lose the ability to make and receive calls via your IP-based trunks.
If this happens:
- You will need to contact your provider to inform them that your public IP has changed.
- We will send a warning email to the subscription owner and registered admin to follow up with the change.
What we recommend
- If you have an IP-based SIP trunk, consider having a second registration-based SIP trunk as a backup. This will provide an alternative route for calls to be made while you wait for your IP-based carrier to update the endpoint with your new 3CX public IP.
- You could also consider porting your number to a registration-based service to avoid those downtimes for good.
SIP trunk providers that require on-premise hardware such as session border controllers, customer premises equipment or internet access via a specific ISP remain incompatible.
