BYOC is a way to keep your existing phone provider while receiving your inbound calls in Close.
It's great alternative to porting your numbers. It also allows you to use Close in countries where we currently don't offer phone numbers (e.g. China or Russia).
BYOC is only works with VoIP phone numbers. You'll need to ask your VoIP provider if it's supported.
BYOC is easier to set up (and revert) than porting. If your provider supports it, it's a great way to test things out before fully porting the number.
Porting requires more paperwork and time. It can take a few days or more, depending on the telephony provider (sometimes they request extra information to verify the requestor identity). You also have to go through the process of porting the number out if you decide to leave Close.
Incoming vs. outgoing calls
BYOC does not impact outgoing calls. All outgoing calls are made through Close's telephony network (however, your caller ID will match your BYOC'd number).
Incoming calls are first routed through your existing carrier, then over to Close (where the call will ring). There's no wait or ring time for the routing change; it all happens seamlessly.
You will still be able to make outgoing calls with your softphone. However, the incoming calls will always be routed to Close. It's not possible to have both your softphone and your Close app ring at the same time.
- Contact your existing carrier to find out if and how to forward your calls to another carrier via SIP.
- Ask your carrier for a list of IP addresses used to forward the calls. We will need them for an IP whitelist to be able to accept incoming calls.
- Send an email to [email protected] and include the the following:
- Name of existing carrier.
- Phone number(s) you wish to forward and their corresponding user account in Close.
- IP addresses from your existing carrier to be added to our whitelist.
- Once you've received confirmation from the Close support team, have your carrier set up forwarding for each of the numbers you wish to use in Close. Have them select a forwarding location based on their geographic location. (This helps minimize latency.):
- Set up a SIP forward rule with your existing carrier. It should have this format: <number>@<hostname from step 4>.
- For example: [email protected]
