What is a Hybrid SIP Trunk?
First of its kind - the Swiss Army Knife of SIP trunks. Hybrid has thrown out the rule book: one trunk that works both ways, with the office features standard SIP leaves behind.
Run as a Cloud PBX
No PBX? Use Hybrid as a fully functional cloud phone system - hold, transfer, parks, queues, softphones and desk phones, without a separate platform.

How billing works
Every Hybrid SIP trunk attracts a $5.00 monthly Hybrid fee, no matter which SIP Trunk plan you use. Call minutes and other plan charges still follow your assigned SIP Trunk plan rate card.
| Scenario | What you pay |
|---|---|
| 1 Hybrid trunk (any plan) | $5.00 Hybrid + plan rates |
| 3 Hybrid trunks | $15.00 Hybrid + plan rates |
| Unhinged + Hybrid trunk | $25.00/month ($20 Unhinged + $5 Hybrid) |
| Standard SIP trunk (compare) | 50¢ connection + plan rates |
| Delete Hybrid trunk mid-cycle | No refund - no pro-rata credit |
Plan rates are separate. Review capacity and call rates on Manage Plans.
Recording & AI
Call recording itself is free. Storage starts when a recorded call is saved. AI features are optional and only bill when enabled and used. Recording storage remains $1.00 per GB per month and is billed separately from AI.
- Storage charged pro-rata by day while files remain
- Retention: keep forever, or auto-delete after N days
- Transcription bills per minute of audio transcribed
- Call Insights bill input + output tokens for enabled features
- Turning a feature off stops new usage; existing files stay until deleted
Tip: Check storage and AI estimates anytime in Recording Management and AI & Transcription.

Common questions
Quick answers about Hybrid fees, recording storage and AI billing.
Is the $5 fee the same on every plan?
Yes. Every Hybrid SIP trunk is $5.00 per month, whether you are on Basic, Business, Unhinged, or another SIP Trunk plan. Plan call rates still apply on top.
What if I am on Unhinged?
Creating a Hybrid trunk while on Unhinged adds $25.00/month for that channel: $20.00 Unhinged plus $5.00 Hybrid. Each component can have a separate charge and renewal date.
Do I pay to record calls?
No per-minute recording fee. You pay $1.00 per GB per month for stored audio, billed pro-rata. Enabling or disabling recording has no fee.
When does AI billing start?
Only after you enable a feature and it runs successfully. Transcription bills per transcribed minute; Call Insights bill tokens for enabled features. Call Recording must be on.
What happens if I delete a Hybrid trunk?
Future Hybrid billing stops. There is no pro-rata credit for the remainder of the current billing period.
Are prices including GST?
Yes. All retail amounts on this page are AUD including GST.
