Point the phone system you already run at our trunk and pay per second for what you use. No minimum commitment, no channel licences, and no rip-and-replace project.
Everything below is what the platform actually does today, not a roadmap. If something you need is missing, ask — we would rather tell you no than have you find out after signing up.
IP authentication is simplest when your PBX has a static address: tell us the address, and calls from it are trusted. Registration authentication suits a PBX on a dynamic connection — it registers to us like a handset would. Registration also survives an address change without a support ticket, which is usually worth the small extra setup.
A compromised PBX dialling premium international ranges is the single most expensive thing that can happen to a SIP account. We cap concurrent calls, block international destinations until an account has topped up, and rate-limit call attempts per trunk. None of that replaces securing your own PBX, but it bounds the damage while you notice.
Consumer and small-office routers routinely rewrite unencrypted SIP in ways that break call setup, and the symptom is a registration that drops every few minutes for no visible reason. TLS traffic looks like ordinary HTTPS, so intermediate equipment leaves it alone. It also keeps your call metadata private in transit. If registrations are unstable, switching to TLS on 5061 fixes it more often than anything else.
Anything that speaks standard SIP: Asterisk, FreePBX, FusionPBX, 3CX, Yeastar, Grandstream UCM, Issabel, and most hardware gateways. We do not require a vendor-specific module.
No. You pay for the minutes you use. Concurrent-call limits exist as a fraud control, not as a licensing product, and we raise them on request.
Yes, for any number on your account. Presenting a number you do not control is refused — that is caller ID spoofing and it is illegal in most jurisdictions.
Calls in progress continue. New calls fail over to the next available point of presence. If your PBX is unreachable, inbound calls follow the failover destination you set on the number.
Every plan carries the full feature set. What differs is capacity.
Create an account and your SIP credentials are issued immediately. No card required.
