Keep your phone system, replace the lines
If your on-site phone system still does the job, you don’t have to replace it. SIP trunks connect it to the phone network over your internet connection instead of old phone lines.

Is this for you?
SIP trunking is for offices that want to keep the phone system they have.
- You have an on-site phone system (PBX) that still works well
- Your calls run over PRI or older copper lines
- You need more lines at busy times, or pay for more than you use
- You want more capacity without new wiring
- You plan to move to a cloud system later, but not yet
What you get
Your numbers, kept
We move your existing numbers onto the new trunks.
Lines that fit your office
Add or remove call capacity as the office changes, without new wiring.
Backup routing
If your site goes offline, calls can go to another number or location.
Works with most systems
Most modern on-site phone systems connect over SIP. We check yours first.
Network and voice together
We look at your internet and your phone lines as one setup, so call quality holds up.
One number to call
When something isn’t right, you call us, and we deal with the carrier.

What changes for your staff
Nothing they’ll notice. Phones, extensions and voicemail stay as they are. The change happens behind the phone system, where the old lines used to plug in.
We test calls in and out before the switch, schedule the cutover for after hours, and check everything the next morning.
Common questions
Something we haven’t covered? Call us on 714-594-6000 and ask.
Will our phone system work with SIP trunking?
Most do. We check the make, model and software version during the free assessment.
Can we keep our numbers?
Yes. Your existing numbers move onto the new trunks.
Do we need a new internet connection?
Sometimes. Calls need a steady connection. We look at your current internet and tell you whether it’s enough.
Can we move to a cloud system later?
Yes. Your numbers can move again when you’re ready, and we can plan that step with you.
Keep the system you have. Replace the lines behind it.
A free phone assessment, with no obligation. Have a recent phone bill handy and it goes faster.
