Managed 3CX Support by Houston Engineers
Houston TechSys provides ongoing managed support for 3CX systems across the Houston metro. Updates, moves/adds/changes, monitoring, and emergency response — handled by the engineers who installed your system.
Why Your 3CX System Needs Active Management
3CX releases multiple updates per year. Each update includes security patches, bug fixes, and new features — but applying updates to a live phone system is not a simple task. A misconfigured update can break SIP trunk registrations, corrupt dial plan rules, or disable CRM integration. Without managed update support, most Houston businesses run outdated 3CX versions for months or years.
Staff changes are the other constant driver of support costs. Every new employee needs an extension created, a phone provisioned, voicemail configured, and their name added to the directory. Every departure needs an extension disabled and voicemail redirected. Businesses without a support plan make these changes themselves — often incorrectly — or let them pile up.
A managed support plan from Houston TechSys ensures your system stays current, your staff changes are handled same-day, and your emergency calls get answered by someone who already knows your system.

What Counts as a MAC Request
A Move/Add/Change (MAC) is any modification to your running system that does not require a new deployment. Common MAC requests for Houston clients include:
Add a new employee extension and provision their phone
Remove or disable a departed employee extension
Update IVR menu options or recorded prompts
Add or change a ring group or call queue
Set up time-based routing for holidays
Configure call forwarding for a specific extension
Add a new DID number to the system
Update voicemail greetings for extensions or ring groups
Add a new location or remote worker
Frequently Asked Questions
Do I have to have purchased a system from you to get a support plan?
No. We take on existing 3CX systems for managed support after a system assessment. We'll review your current configuration, document any issues, and onboard you to the appropriate plan.
What is your emergency response time?
On the Professional plan, outage response SLA is 2 hours during extended business hours. On Enterprise, emergency response is 24/7 with a 1-hour SLA. Emergency means total loss of inbound or outbound call capability.
Are 3CX license renewals included?
3CX annual license renewals are a separate cost billed directly by 3CX or passed through at cost. Your support plan covers labor for applying updates and managing the system — not the license fee itself.
Can we cancel the support plan?
Plans are month-to-month after the initial 3-month term. No long-term contracts required.
Do you support 3CX hosted on our own server?
Yes. We support self-hosted, cloud-hosted (Azure, AWS, Google Cloud), and 3CX-hosted instances. The support scope is the same regardless of platform.
