Frequently Asked Questions
How many channels do I need for my trunk?
You choose the number of channels based on your expected concurrent call volume — 5 channels is the minimum, and you can scale up to as many as you need. You’re only billed based on your selection.
Do I need to register my SIP device, or can I connect without registration?
Both are supported. If you have a static public IP, you can use IP Whitelisting (Direct-IP) to send calls without SIP registration credentials. See our IP Whitelisting setup guide for the steps.
How do I point an incoming number to my trunk?
From Inbound → Local Numbers, use the Call Forward option on the number, select Direct-IP as the destination, and enter your trunk’s WAN IP. See our step-by-step guide.
Can multiple accounts share the same IP address?
Yes — if multiple customers send calls from the same IP, a Prefix or X-Header must be added to each whitelist entry so PBXme can identify which account each call belongs to.
Can I test compatibility before committing?
Yes. Use our free Test Service to confirm your IPBX is compatible before signing up.
