FreePBX + Cliqtel: Use Cases

Replace your current SIP provider

Migrate your FreePBX system from an expensive SIP provider to Cliqtel without changing your PBX configuration — same SIP protocol, transparent per-number pricing.

Add international numbers to FreePBX

Expand your FreePBX deployment with local, toll-free, and mobile numbers in 70+ countries. Assign them to extensions or queues exactly as you do today.

Failover and redundancy

Add Cliqtel as a secondary SIP trunk for FreePBX to fail over when your primary carrier has an outage. Keep your customers reachable 24/7.

Frequently asked

FreePBX Integration — FAQ

How do I connect Cliqtel to FreePBX?
Create a SIP trunk in your Cliqtel portal, copy the credentials, and paste them into FreePBX's SIP provider settings. A full step-by-step guide is in the setup steps above.
Does Cliqtel work with my version of FreePBX?
Cliqtel supports all current and recent versions of FreePBX. Check the supported versions list above or contact support if you're running an older release.
How much does it cost to use Cliqtel with FreePBX?
Cliqtel has no setup fees, no monthly platform fees, and no channel limits. You pay only for the DID numbers you rent (from EUR 1.49/mo) and the minutes you use. See our pricing page for details.
Can I use my existing phone numbers?
Yes. Cliqtel supports porting for most countries. Contact support with your existing numbers and we'll check portability and timelines (typically 5-10 business days).
Does FreePBX need any special firewall configuration?
Open UDP 5060 (SIP) and UDP 10000-20000 (RTP) outbound to sip.cliqtel.com. Most PBX systems handle this automatically if you're not behind a strict NAT.
