Replace Your Trunk Provider

Overview

Traditional trunk providers bundle minutes, charge per-channel fees, and lock you into 12-24 month contracts. DIDfarm replaces all of that with flat per-number pricing: you pay for your numbers, inbound calls are free, and there are no channel limits or bundled minute packs.

The migration typically takes under an hour for the SIP trunk setup, plus 5-15 business days for number porting (if you're keeping your existing numbers).

Migration Checklist

1. Audit current setup — list all numbers, trunk settings, inbound routes, and outbound rules
2. Create DIDfarm account and top up wallet
3. Create SIP trunk on DIDfarm and configure your PBX
4. Test with new numbers — order temporary DIDfarm numbers to verify calls work
5. Port existing numbers — submit LOA to DIDfarm for number transfer
6. Cutover — once porting completes, switch PBX to DIDfarm trunk
7. Cancel old provider — after 2-week parallel run

Step 1 — Create DIDfarm Trunk

1. Go to My Numbers → SIP Trunks → Create Trunk
2. Name it (e.g., "Office PBX")
3. Copy the SIP credentials: username, password, SIP server (sip.didfarm.com)

Step 2 — Configure Your PBX

Add DIDfarm as a second trunk on your PBX (don't remove the old one yet). See our platform-specific guides:

• 3CX setup guide
• FreePBX setup guide
• Asterisk setup guide

Step 3 — Port Your Numbers

1. Contact DIDfarm support with a list of numbers to port
2. We'll send you a Letter of Authorization (LOA) to sign
3. Submit the LOA along with a recent invoice from your current provider
4. Porting typically takes 5-15 business days depending on the country
5. We'll notify you when the port is scheduled and when it completes

Step 4 — Cutover

1. Once porting completes, your numbers are live on DIDfarm
2. Update your PBX inbound routes to use the DIDfarm trunk
3. Update outbound routes to prefer the DIDfarm trunk
4. Run a 2-week parallel period with the old trunk as failover
5. After 2 weeks with no issues, remove the old trunk and cancel the old provider

Rollback Plan

If anything goes wrong during migration:

• Before porting: Simply remove the DIDfarm trunk from your PBX. Nothing changes for your callers.
• During porting: Contact DIDfarm support to cancel the port. Your numbers stay with the old provider.
• After porting: You can port numbers back to another provider if needed (though this is rare).

FAQ

Will there be downtime during migration?

No. Number porting is designed to be seamless — calls switch to the new carrier within seconds. There's typically less than 30 seconds of unavailability during the actual port, and it's scheduled during off-peak hours.

Can I keep my current numbers?

Yes. We support number porting from most carriers in the EU, US, UK, and other major markets. Contact support to confirm portability for your specific numbers.

What if I have a contract with my current provider?

You may face early termination fees from your current provider. However, DIDfarm's cost savings often pay back the termination fee within 2-3 months. Calculate your ROI before committing.
