Before You Book
We can only provide ad hoc support where the underlying installation follows supported 3CX deployment practices. All assistance is remote.
Support does not include
- Unsupported SIP trunk providers
- Unsupported SIP phones or endpoints
- Installations that do not follow 3CX recommended deployment / best practices
- Troubleshooting third-party equipment or services outside the 3CX environment
- On-site engineering
- Replacement or supply of faulty hardware
Hosted 3CX & phones at your premises
Where your PBX is hosted remotely or in the cloud, your premises-based SIP phones must connect using a supported architecture. This must normally be either:
- A 3CX SBC (Session Border Controller), or
- A site-to-site VPN between your network and the hosted 3CX environment.
We may advise that changes are required before troubleshooting can continue.
Engineering time is chargeable: this includes time spent identifying an unsupported or incorrectly configured deployment. Purchasing support does not guarantee every fault can be resolved within the time purchased.
