How to Connect

Create PJSIP objects

Add auth, AOR, and endpoint objects to your pjsip.conf (or pjsip_custom.conf) using the credentials below.

Add dialplan context

Create a [from-didfarm] context in extensions.conf to handle inbound calls from DIDfarm numbers.

Reload and validate

Run "pjsip reload" from the Asterisk CLI. Check registration with "pjsip show registrations".

Run test traffic

Call your DIDfarm number and verify it hits the correct dialplan context. Check SIP traces if needed.

Asterisk + Cliqtel: Use Cases

Replace your current SIP provider

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

Add international numbers to Asterisk

Expand your Asterisk 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 Asterisk to fail over when your primary carrier has an outage. Keep your customers reachable 24/7.

Asterisk Integration — FAQ

How do I connect Cliqtel to Asterisk?

Create a SIP trunk in your Cliqtel portal, copy the credentials, and paste them into Asterisk's SIP provider settings. A full step-by-step guide is in the setup steps above.

Does Cliqtel work with my version of Asterisk?

Cliqtel supports all current and recent versions of Asterisk. 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 Asterisk?

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 Asterisk 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.
